When to use BufferedInputStream/OutputStream/Reader/Writer

I'd be very grateful if someone could explain when to use BufferedInputStream, etc., and what the dis/advantages are.
TIA
Shaun

data channels such as files sockets, etc, tend to be
a) slow
b) block oriented
BufferedOutputStream attempts to mitigate this by presenting data in block format. Rather than a bunch of little segments of bytes.

  • I use LabVIEW 7.1 but I have some problem when, I use LabVEW to read the data from serial communication

    I use LabVIEW 7.1 but I have some problem when, I use LabVEW to read the data from serial communication.
    I use LabVIEW to read the data from serial communication then, i open the example (.vi) from Serial Communication - Advanced Serial Write and Read  from LabVIEW Example. BUT it have some error message that : Error - 1073807202 occured  at property node in visa configure serial port (instr).vi -> advance serial write and read .vi
    this error code is undefined. no one has provide a description for this code, or you might have wired a number that is not an error code to the error code input.
    I don't know why? please help me. thank you.

    When I copy that code into "Explain Error" I get: "VISA:  (Hex 0xBFFF009E) A code library required by VISA could not be located or loaded."
    You may have a bad install of VISA or the wrong version of VISA loaded. Try re-installing VISA. You can get the latest version from the NI support site: http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C0E91?opendocument&node=1....
    Also ensure that you are not pointing the example towards a serial port that does not exist.
    Please let us know what you find and what gets this working for you.

  • InputStream - OutputStream: Reader - Writer

    What was not possible by InputStream & OutputStream that JAVA had to provide Reader and Writer. I have found out that if I use InputStream to read a Chinese HTML page, it reads it. I can create a copy of the same HTML page by using OutputStream, the data remaining un-affected. Then, why do I go for Reader and Writer?
    What happens if InputStream encounters some unicode charchters to be read? How does InputStream and OutputStream function internally?

    Well, you can go look at the source of InputStream/OutputStream.
    The reason we have Reader/Writer as well is because the streams don't deal with character encoding (or at least, they tried to and did it very badly). So you would normally use streams for dealing with binary data and reader/writer for dealing with character data. If you're using streams to copy a file and this file happens be be HTML with Chinese characters, this will work fine because you're just duplicating bytes. But if you try and use a stream to read this file into memory, you will have problems because it won't understand the Unicode characters in the file. In this case, you need to use a Reader and tell it what the character encoding of the file is.

  • Can't update photos using iPhoto 6 - read/write permissions

    Help!
    Before you think this is the standard "iPhoto 6 permissions problem", please read on.
    Upon installing iPhoto 6 and attempting to update my iPhoto Library, I get the dreaded "There is a problem accessing...files in your iPhoto Library folder...Make sure you have read and write permissions for the folder...all enclosed items." This is the problem noted in:
    http://docs.info.apple.com/article.html?artnum=303135
    However, it doesn't tell me what file(s) have the problem, even though the app note says it would for OS 10.3.9. No matter. I simply first did a get info on the iPhoto Library folder verified that it was not locked and that I had read/write permissions. I also applied that to everything inside the folder. Ran iPhoto again...same error.
    Although I didn't get the "repair permissions" error, I did that too. Ditto for the locked files issue reported at:
    http://docs.info.apple.com/article.html?artnum=303232
    After attempting the update at least a dozen times, I even tried the UNIX chmod command (774) on everything in the iPhoto Library folder just in case the "get info" method didn't take. Still get the same error when updating iPhoto 6. What gives!
    I willing to try any suggestions ya'll might have!
    FYI - I do have my older version of iPhoto available and I have a complete backup of my iPhoto Library.
    Thanks!

    Hi David,
    It's up to you, unless someone else comes along with some more things to try.
    I am assuming you still have a version 5 of the iPhoto Library folder in the Finder.
    Rename it to iPhoto Library_old and drag it to the desktop.
    Do a search in the library for Thumbs. this will find all the Thumb folders which you do not want to import into the new Library. Delete those Thumb folders.
    Now you have to decide if you want to import both the Original and Modified versions of a photo, or just the Originals. The problem is, if you import both, they will no longer be linked but will show up as separate photos in the library.
    Actually it is going to be a big pain unless you have just the photos backed up to reimport.
    If you want, you can check out a page I made showing the manual way to import the photos (#3)

  • FPGA Read/Write Control Issues

    Hello all!  Rather new to using FPGA, but I have an interesting issue that's popping up.
    Currently pulling in RAW voltage data from a set of sensors (Pressure Transducers, Load Cells, etc) through a cRIO DAQ.  Have the FPGA file setup to pull in that data already and have the main VI and all the sub-VIs working just fine.
    What I'm trying to do is save the raw voltage data (TDMS files) on the lower level and the convert and display on the upper level so that I don't have to convert and save (speed up saving data).  So that leaves 3 distinct levels/sections:
    On FPGA that pulls in the raw data
    On FPGA that saves the raw data
    Main VI that does all the controls/conversions/displays etc.
    Number two is where I'm having an issue.  I want to save all the data in parallel so I'm creating a save FPGA for each I/O device (8 Relays to command solenoid valves, 3 Pressure Transducers, 1 Load Cell, 4 Thermocouples).  To do this I want to create a separate VI for each device (not sure if that's a smart thing to do).
    The issue I'm having is when I use the FPGA Read/Write control to read in from the Target and save to the TDMS.  When I only use a single FPGA target reference the lines are broken, but as soon as I switch to two targets, it now works.
    Any reason why it might be doing this?  Any ideas/suggestions at all on how to go about setting this up in general?
    Thanks!

    You might check the documentation for "data" terminal of "TDMS Write" (http://zone.ni.com/reference/en-XX/help/371361H-01/glang/tdms_file_write/). One DBL element is not accepted, but 1D DBL array is accepted.
    data is the data to write to the.tdmsfile. This input accepts the following data types:
    Analog waveform or a 1D array of analog waveforms
    Digital waveform
    Digital table
    Dynamic data
    1D or 2D array of:
    Signed or unsigned integers
    Floating-point numbers
    Timestamps

  • Incorrect data type when writing to FPGA Read/Write Control

    I have run in to a problem this morning that is causing me substantial headache.  I am programming a CompactRIO chassis running in FPGA mode (not using the scan engine) with LabVIEW 2012.  I am using the FPGA Read/Write Control function to pass data from the RT Host to the FPGA Target.  The data the RT host is sending comes from a Windows host machine (acting as the UI) and is received by the RT Host through a network published variable.
    The network published shared variable (shared between the RT and Windows system) is a Type Def cluster containing several elements, one of which is a Type Def cluster of fixed point numerics.  The RT system reads this shared variable and breaks out the individual elements to pass along to various controls on the FPGA code's front panel.  The FPGA's front panel contains a type def cluster (the same type def cluster, actually) of fixed point numerics.
    The problem comes in the RT code.  After I read the shared variable I unbundle the cluster by name, exposing the sub-cluster of fixed point numerics.  I then drop an FPGA Read/Write Control on the RT block diagram and wire up the FPGA reference.  I left click on the FPGA Read/Write Control and select the cluster of fixed point numerics.  I wire these together and get a coercion dot.  Being a coercion dot hater, I hover over it the dot and see that the wire data type is correct (type def cluster of fixed point numerics), but the terminal data type is listed as a cluster containing a Boolean, code integer and source string, also known as an error cluster.  I delete the wire and check the terminal data type on the Read/Write Control, which is now correctly listed as a type def cluster of fixed point numerics.  Rewiring it causes the terminal to revert back to the error cluster.  I delete the wire again and right click on the terminal to add a control.  Sure enough, a type def cluster of fixed point numerics appears.  Right clicking and adding an indicator to the unbundle attached to the network shared variable produces the proper result.  So, until they are attached to each other, everything works fine.  When I wire these two nodes together, one spontaneously changes to a error cluster.
    Any thoughts would be appreciated.

    My apologies I never got back to responding on this.  I regret that now because I got it to work but never posted how.  I ran in to the exact same problem today and returned to this post to read the fix.  It wasn't there, so I had to go through it all over again.
    The manifestation of the problem this time was that I was now reading from the Read/Write FPGA front panel control and writing to a network published shared variable.  Both of these (the published shared variable and the front panel control) were based on a strict type defined cluster, just like in the original post.  In this instance, it was a completely different cluster in a completely different project, so it was not a one-off thing.
    In addition to getting the coercion dot (one instance becoming an error cluster, recall), LabVIEW would completely explode this time around.  If I saved the VI after changing type definition (I was adding to the cluster) I would get the following error:
    Compile error.  Report this problem to N.I. Tech Support.  Copy cvt,csrc=0xFF
    LabVIEW would then crash hard and shutdown without completing the save.  FYI, I'm running LabVIEW 12.0f3 32-bit.
    If I would then reopen the RT code, the same crash would occur immediately, ad nauseam.  The only way to get the RT code to open was to change the type defined cluster back to the way it was (prior to adding the new element).
    I didn't realize it last time around (what originally prompted this post), but I believe I was adding to a type def cluster when this occurred the first time.
    So, how did I fix it this time around? By this point I tried many, many different things, so it is possible that something else fixed it.  However, I believe that all I had to do was to build the FPGA code that the RT code was referencing.  I didn't even have to deploy it or run it... I just had to build it.  My guess is that the problem was the FPGA Reference vi (needed to communicate with the FPGA) is configured (in my case) to reference a bit file.  When the development FPGA Main.vi ceases to match the bit file, I think that bad things happen.  LabVIEW seems to get confused because the FPGA Main.vi development code is up and shows the new changes (and hence has the updated type def), but when you ask the RT code to do something substantial (Open, Save, etc), it refers to the old bit file that has not yet been updated.  That is probably why the error getting thrown was a compile error.
    I'm going to have to do an additional round of changes, so I will test this theory.  Hopefully I will remember to update this post with either a confirmation or a retraction.

  • G710 hard drive read/write speed

    Hello,
    I have a brand new Ideapad G710  with 1TB Serial ATA 2, 5400rpm with advertised speed of 3 Gb/s (= 384MB/s).
    I am running Windows 7 ultimate x64 with SP1.
    When I test hard drive read/write speed (I used CrystalDiskMark) I get results of about 100MB/s, which is 3-4 times slower than it should be.
    I am not running any resource heavy applications (Resource monitor reports Disk I/O to be 0 most of the time in idle state). I have 3 partitions, each with 16-32GB paging file size and all are >90% empty. All partitions have been defragmented before testing.
    Is this normal? Are there any lenovo drivers or utilities than I might be missing or that can slow/speed this?
    Solved!
    Go to Solution.

    hi Daew,
    Welcome to the Lenovo Forums.
    The results that you got while running CrystalDiskMark is normal. The SATA 2 (3Gb/s) that you mentioned is actually the SATA interface support, not the actual read/write performance.
    If you have a Seagate HDD (eg. ST10000LM024), check these specs
    From the above specs, the unit has a cache that has a read/write max speed of 145 MB/s but there are environmental factors and power requirements to get this speed (eg. read/write speed on AC power is differente from battery power).
    AFAIK, if this is the specs that is design for this drive, there's no way to speed it up.
    If you're planning to upgrade in the future though, you can get an SSD for faster read/write.

  • Online vs Read Write

    I have a confusion in following commands about tablespace.
    When should we use Online and Read Write.
    SQL> ALTER TABLESPACE imp_dat ONLINE ;
    SQL> ALTER TABLESPACE imp_dat READ WRITE ;
    If ONLINE tablespace allow READ/WRITE both, then why is Read Write for?
    Need more clarifications plz.

    do you want to know the difference between ONLINE/OFFLINE and READ ONLY/WIRTE.
    if the tablespace is READ ONLY it is available to select the data from.
    if the tablespace is OFFLINE then you can not even select from it.
    hope this is the answer of you question.

  • NFC tags read/write operations on low level

    Hi,
    I know this is little bit offtopic question - but since you are experts in the area I will try to ask you probably a pretty simple question:
    1/ I would like to know which protocol is used for the read/write operations to the NFC tags are used. According to my understanding after the tag is placed on the NFC reader (NFC phone, USB reader), it is powered and set to the ready state. Then the application protocol for read/write operation is used. As I think the exact format and the content of commands used for read/write is not specified in ISO 14443 and it is dependent on a tag hardware/manufacturer and will be different for FeliCa/Mifare/Innovision/etc. tags, so there is no way how to handle NFC tags read/write operations with the single implementation. Is that assumption correct?
    2/ Are there any tags, which supports the APDU 7816-4 commands for read/write operations?
    Thank you for reply
    Kind regards,
    STeN

    hello,
    you have to read the NFC forum specs. all of this will be better explained than by me.
    more than one protocol are used according the the contactless front end configuration and abilities. It includes ISO14443-A, ISO14443-B and Felica. Sometimes other protocols are also available, for example Innovatron (not Innovision lol)
    Mifare is not a protocol, it is a line of NXP products. These products use the lower layers of the ISO14443-A protocol specification.
    There are 4 types of tags
    1) using the lower layers of ISO14443-A
    2) using the lower layers of ISO14443-B
    3) something related to felica?
    not sure exactly about these 3, you have to read the specs. Everything is clearly understandable, not like ETSI.
    4) something using ISO7816-4 commands on top of ISO14443 A or B or others. You have SELECT, READ BINARY, UPDATE BINARY. You can implement that using javacard, I did it and it works. You need two binary files, that can be hardcoded.
    Regards

  • To have great read/write performance, do you have to save all programs onto the SSD or can you save programs onto the HDD?

    if I want to use the fast read/write speeds of my SSD, do I have to save the programs (Final Cut Pro X, Adobe After Effects, Microsoft Powerpoint, Steam, Counter-Strike, etc)  onto the SSD? Or can I save all programs onto a 2nd drive which would be a HDD  and still have fast speeds WITHOUT storing those programs onto the SSD? My 2012 mid Macbook Pro has a SSD as its main bootup drive and will be getting a 2tb HDD to replace the optical drive.
    Any advice or comments is greatly appreciated,
    Thank you!

  • Read/Write Adobe Reader Capability for iPad

    In my work, I need to be able to write, (make changes) to a PDF file. I use Adobe Reader for this. Does the iPad support use of a read/write version of Adobe Reader? Thank you.

    The capability you are referring to is a function of Adobe Acrobat, not Adobe Reader. On a laptop/desktop Acrobat to convert any file in any native application on that machine (Web, Word, Excel, etc.) into PDF format by "printing" to the Adobe PDF "printer".
    There is no such on the iPad. Previously created PDF documents may be transferred from your laptop to the iPad and viewed on it, and you can also annotate that transferred PDF document (using an app called iAnnotate), but in general you cannot CREATE a PDF document the way you did on your laptop. The only exceptions I can think of are the Apple apps (Pages, Numbers, and Keynote) which allow you to export their files in PDF format. But, as an example, if you want to view a web page and "print" it to a PDF file, no can do.

  • Question on SNMP Read-Write String ...

    Hi,
    My question is that if I am using an SNMP read-write community string on the device, would Prime LMS still require
    the logging credentials of the device via ie) telnet/ssh ?
    The reason how I undertand this as long as the SNMP manager (Prime LMS) and the agent (end device) have the same read-write community,
    couldn't the Prime LMS just write to the device without the standard logging credentials ? or is the logging credential of the device is a must for it
    to push configuration to the device ?
    Pls advise.
    Many thanks.
    Cheers,
    - sn -

    Even though the SNMP communication is there between device and LMS, it is not possible to configure any device using SNMP, except for the RW variable and OIDs, which are limited in their scope.
    It is not possible to configure, but to copy configuration to or from device using SNMP. See the following document to check further:
    http://www.cisco.com/en/US/tech/tk648/tk362/technologies_configuration_example09186a0080094aa6.shtml
    Many people use this manual process to copy configuration from device using SNMP, edit it and copy back to device to make configuration changes, but ideally no NMS server does it and LMS is no exception.
    It uses transport Layer protocols like telnet/ssh to communicate with device like a normal user to configure commands, which in this case is done by Netconfig job.
