Difference between Boolean.valueOf(true) and Boolean.valueOf("true")?

I don't quite understand the difference between Boolean.valueOf("true") and Boolean.valueOf(true)? This might explain why I don't understand why
Boolean b1 = new Boolean("true");
Boolean b2 = new Boolean("true");
System.out.println(b1 == b2)
returns true if we are comparing references? So is there one reference that always represents true and one that represents false?

I don't believe that! If you create two instances using new, you must get distinct references.
If you use the static method Boolean.valueOf(boolean), the documentation states that you will get one of the built-in constants Boolean.TRUE or Boolean.FALSE. The documentation for Boolean.valueOf(String) makes no such promise, but I suspect it will do so anyway.
The difference is not significant (apparently) when you use literals as here. The difference comes when you have
Boolean.valueOf(s), where s is a string variable, which may contain "true", or "false", or "Uncle Fester", or any other string.

Do we have a way to get the differences between xtext model before and after partial parse?

Do we have a way to get the differences between xtext model before and after partial parse?
As an example i have file contains 4 lines, xtext parsed this file and generated its model, then i made small modification in line number 3, so xtext partially parsed the file and generated another model.
The question is could we get the nodes that has been deleted from the model?
could we get the new nodes added to the model?
could we get the differences between the two models?

Re: DIfference between Schemas, PCRS' FUnctions and Operations

Dear SAPExperts,
Can anybody pls tell me what is difference between Schemas, PCRS' Functions and Operations.
Thanx in advance
Regards
Aniruddha

Hi Aniruddha
When the payroll driver is executed (for ex: PC00_M40_CALC for INDIA is executed) the schema IN00 (standard schema) is executed and it calls certain functions (functions may use Rules. Rules contain Operation) and also subschemas.
Functions could be of four types
1. Performing some payroll computations (E.g. INEPF function calculates the PF amount of an employee during payroll run)
2. Calling rules (E.g. P0045 function calls a rule INLN to compute the loan details of a personnel number).
3. Getting data from Infotypes (E.g. P0581 will get the data from Infotype-581 for payroll processing).
4. For some decisions. (E.g. IF & ENDIF function is used to execute as per the true and false decisions) etc.
When the PY is executed SAP uses lot of Internal Tables to store data and also provides data to other internal tables.
The read and change access to Internal Tables is enabled using functions that are executed in a personnel calculation schema and using operations that are executed in personnel calculation rules.
The following is just an attempt to provide some info on how Functions are processed during the PY Run. For ex: (functionality of subschema XIN0 and INBD)
1. INITIALIZATION OF PAYROLL: When the Payroll is executed first the subschema XIN0 is called,   This subschema comprises the following main steps:
I.     Specify program type (payroll or evaluation)
II.     Set switch for database updates (YES/NO) all database updates are controlled via this switch (otherwise simulation)
III.     Only infotypes from the HR master record which apply to the selected personnel number are read.
IV.     All Time Management infotypes are imported.
V.     Specify check against control record PA03 (test or live).
2. READ BASIC DATA: Once the Initialization of Payroll is successful, the subschema INBD is called. This subschema reads the Basic data of an employee who is there in the Payroll execution. Basic Data includes, determining Employee Name, Reading Work Center/Basic Pay Data, Setting Financial Year Dates and Allowance Grouping Tables, Reading Previous Employment Tax Details, Reading Housing (HRA/CLA/COA), Reading Exemptions, Reading Income from Other Sources, Reading Section 80 Deductions, Reading Investment Details (Sec 88), Reading Provident Fund Contributions, Reading Other Statutory Deductions, Reading Car and Conveyance, Reading Long Term Reimbursements, Read ID Details. Function GON checks whether all the master data has been imported, no further processing of schema will occur unless certain data is present.
The Subschema INBD calls the following functions in order to read the Basic Data:
ENAME :
Function ENAME reads the last valid name of the employee in the payroll period. The formatting used for the country in question is used when displaying this name.
WPBP
If an employee receives a pay increase within a payroll period, the Basic Pay infotype (0008) is changed and delimited as of a specific date. Two data records exist for one payroll period.
During payroll, the system writes the Basic Pay wage type to the results table with two different indicators. These split indicators are a link to the WPBP table that contains the relevant values. The system takes into consideration both data records for the corresponding partial periods when calculating remuneration.
ININI
P0580
P0581
P0582
P0584
P0585
P0586
P0587
P0588
P0583
P0590
P185I
GON :
                Function GON checks whether all the master data has been imported. No further processing of the schema will occur unless certain data is present. Checking procedures vary from country to country. There must always, however, be a work center (P007).
[Def. of Functions, Rules and Operations (copied from Raju's answer)
Schema is a collection of functions
A Rule is a collection of operations.
An operation is a very basic piece of logic that is used, mostly, to manipulate wage types

Difference between center,edge mmcm and edge direct allignments

What is the difference between center, edge mmcm and edge direct allignments.

Both of these terms are used most often used (but not exclusively) when describing source synchronous interfaces.
Edge Aligned vs. Center Aligned
When a device uses source synchronous communication, be it a device that sends data to an FPGA (an input to the FPGA) or a an FPGA sending data to an external device (an output of the FPGA), the device needs to define and describe the timing relationship between the clock and the data that it is forwarding to the other device. The receiving data needs to know this timing relationship in order to devise a mechanism to capture the data.
The timing relationship can really be just about anything, but two types are common:
Edge Aligned:
This is the simplest for the transmitting device. The device simply generates the forwarded clock and data using the same mechanism. If the sending device is an FPGA, then it uses an internal clock to drive an ODDR that drives the forwarded clock, and uses the same clock to send the forwarded data, either using an IOB flip-flop (SDR) or an ODDR flip-flop (DDR).
Using this mechanism, the timing relationship is often (but not always) described as a skew; i.e. the data will change +/-200ps around the edge/edges of the clock.
Of course, this clock/data timing relationship can rarely be used "as is" by the recieving device, so the receiving device will be responsible for adding some delay or other mechanism to use the forwarded clock to capture the forwarded data (i.e. an MMCM shift or an IDELAY).
Center Aligned:
This is supposed to be the simplest mechanism for the receiver. The transmitter uses some internal structure to place the edges of the forwarded clock in the middle of the forwarded data valid window. In an FPGA (as a transmitter), an internal clock would drive an ODDR for the forwarded clock, but the forwarded data would be driven from either an IOB FF using an inverted clock (SDR) or an ODDR using a clock that is 90 degrees out of phase (DDR). (Or it could be vice versa - the data uses the normal clock, and the forwarded clock uses the inverted or 90 degree clock).
Using this mechanism, the clock/data relationship is often (but not always) defined as a provided setup/hold relationship around the forwarded clock; i.e. the data will be valid 1.5ns before the edge of the clock and remain valid for 1.5ns after the edge of the clock.
The idea is that using this timing relationship, the receiver should be able to use the forwarded clock as is to capture the forwarded data. In general, though, this is rarely true, since most devices don't have an equal required setup and hold time; so the receiver still needs to modify the clock/data relationship to center its required window in the provided window.
MMCM vs. Direct Capture
This is a different concept. Regardless of which alignment is used (edge, center or something in between), the receiver (now we are assuming it is the FPGA doing the reception) needs to implement some clocking mechanism to use the forwarded clock to capture the forwarded data. There are really two styles:
Direct Capture:
The forwarded clock is brought in and goes directly to a clock buffer (either BUFG/BUFH or BUFR/BUFIO), which is used to capture the incoming data. Generally (as I said above), the clock/data timing relationship needs to be changed, and when using this capture mechanism, this can only be accomplished using an IDELAY on the clock or data (or both). When done this way, the clock has a propagation delay through the delay element (the IDELAY)
MMCM Capture:
Here, the forwarded clock is brought in on a clock capable I/O, then through an MMCM and from there to a BUFG or BUFH (with feedback to the MMCM). When done this way, the "common" way of modifying the clock/data timing relationship is by adjusting the phase delay of the MMCM output clock.
There is a subtle but extremely important difference in Vivado (and SDC/XDC) between a propagation delay and a phase delay (or phase shift). It has to do with how the tool determines which clock edge will capture data that is generated by a particular clock edge.
When we use a set_input_delay, we describe to Vivado a data window associated with a particular clock edge. By default, that data window will be captured by the next edge of the clock. The definition of the next edge is different when using these two mechanisms.
When a clock edge is propagated through a delay element, the resulting clock is the same edge. Lets take the example of a 10ns clock (rising at 0ns, falling at 5ns) with a 2ns delay (using an IDELAY) capturing an SDR data. The rising edge at time 0ns will generate a data window. By default, it will be captured by the next clock edge, which is at 10ns. After the 2ns of propagation delay, the internal clock at 12ns will be used to capture the window.
When a clock is phase shifted, a new clock is generated. Using the same example using an MMCM, the output clock of the MMCM rises at 2ns and falls at 7ns (and rises again at 12ns). So, the data window defined by the first rising edge of the input clock (at time 0), will be captured by the next rising edge of the phase shifted clock, which is at 2ns (this 2ns rising edge of the phase shifted clock is the "next" edge after the 0ns edge that generated the data window). This is different than the previous example, where the internal edge at 12ns (not 2ns) would capture the first window.
As a result, the constraints you use to describe the timing relationship (the set_input_delay) needs to be different between these two styles. Its also a bit messy, since the constraints that are correct for an MMCM with 2ns (or even 0.01ns) of phase delay are not correct for an MMCM with 0ns of phase delay (which is a bit icky).
I hope that clears things up!

What is the difference between HP 500 series and 110 series?

I'm not Tech savvey so I'm confused about the differences between the HP 500 and 110 series. The thecnical specks look simmilar so which is better?

A true comparison would need the model numbers (not the series) to be specific. Overall, the 110 series is considered the entry-level or value line while the 500 series is the mid-range line.

What is the differences between T=0 protocol and T=1 protocol?..

Hi friends..
Sorry, i want to know what is the differences between T=0 protocol and T=1 protocol?..
Which one is the best, Java Card that support for T=0 protocol and Java Card that support for T=1 protocol?..
Thanks in advance..

Sebastien_Lorquet wrote:
Such protocols have NOTHING TO DO with javacard. They have been existing for YEARS before javacard was invented.
It's just a mean to exchange data with any card. It happens to be a standard, so javacards among others use it to communicate with the host.
the Javacard spec by itself does not know anything about how the APDUs are exchanged . It can be T=0, T=1, T=14, RS-232, GPIB, USB, ISO14443, Felica, Ethernet, Firewire, a satellite link, a deep space link, or anything you want. The comm part is the responsibility of the card operating system, which is out of scope for the javacard machine that lies onto it.
Just because you have a convenience method in the APDU class does not mean this is real. It's up to the card / os manufacturer to define these things, it's reasonable to think they are accurate, but I can create a javacard that claims to be contactless and still will use T=0. That's arbitrary.This is not exactly true. For APDU response chaining to work on some T=0 cards (when using smartcardio that handles response chaining for the developer) we had to use some special tricks. It can also be handy to only allow certain actions on the contact interface (such as admin actions etc) to prevent unauthorised access. The [PLAID Applet|https://www.govdex.gov.au/confluence/display/PLAID/Home;jsessionid=9B9EC664A01EC13B098DDF4EE5760A0A] (developed by the Australian fegral government agency Centerlink) only allows the card to be initiliased through the contact interface.
- T=0 requires a GET RESPONSE additional exchange only for case 4 commands or when the command provides more bytes than requested for an outgoing command. It can also require more than two exchanges if the terminal requests the outgoing data per-block.Don't forget case 2. The GET RESPONSE is at TAPDU layer and is handled internally by smartcardio/PCSC etc and is also handled by the smartcard OS.
Leonardo, if you want to know the differences between the two, I recommend reading ISO7816-3.

Shane

Anyone know what is the difference between AIR-ANT5135D-R and AIR-ANT5135DB-R ?
From the dynamic configuration tools for 1252 and 1242, AIR-ANT2422DB-R is inside one of the antenna option.
However, I can't find it in the "Cisco Aironet Antennas and Accessories Reference Guide"
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html
Inside the document there is only AIR-ANT5135D-R.
likewise for the 2.4 GHz, AIR-ANT2422DB-R is inside the dynamic configuration tools and not inside "Cisco Aironet Antennas and Accessories Reference Guide"
Any help would be appreciated
Thanks,

The difference between Telepresence Content Server and MSE 3500

Good day! Could someone explain me what's the difference between Telepresence Content Server and MSE 3500? Why do I need to obtain two these devices for sorting out my tasks? I want to understand gist of the first and the second devices.

In addition to what Jonathan posted above, here is a Capture Transform Share Solution Guide that goes over a little bit of what the TCS and MXE are and some possible deployment scenarios.
In short, TCS is used to record video conferences or lectures that can be streamed on demand or live using various streaming or distribution methods. One such distribution method is using the MXE 3500 to ingest the recordings from TCS and convert them to different media types and add in-video content such as logos etc. However, from the MXE, you can't send the video back to the TCS for viewing, you'd need to send that off to another viewing portal such as Show and Share.

What is difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?

What's the difference between a web site and a web application?

I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
Or maybe I'm totally wrong here - what differenciates between a web application and a website?

This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
runs remotely, and it depends fundamentally on a processing and a data storage backend.

There is no real "difference". Web site is a more anachronistic term that exists from the early days of
the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
more like an application as a web app.
The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.
