Access cell factory instance

Question

I have a tableview with a single column. I associated a cellfactory to it as given in the below code. I am trying to loop through all the cells values of a table column on click of a button. I am not sure how to get hold of cell's inner class instance i.e.EditingCell class as said in the given example. Please help me with the same code for this.
2. Also, I have a requiremet where in I want to change the alignment or for example change the value of that cell on click of a button, by looping through all the rows of a single column. I know how to change in the underlying datastructure, but this is not what I want. I want to loop thru by getting value using cellfactory or cell value factory. any help will be of great use.
Callback<TableColumn<Person,String>, TableCell<Person,String>> cellFactory =
    new Callback<TableColumn<Person,String>, TableCell<Person,String>>() {
        public TableCell<Person,String> call(TableColumn<Person,String> p) {
            return new EditingCell();
firstNameCol.setCellFactory(cellFactory);Thanks.

Answer 1

I think that's much too mighty for a general development user ;)But it'll teach 'them general development users' on how things work, while they're developing, using a representative dataset(!).
I would let them select anything they're interested in regarding resources, stats, execution plans etc, on the appropriate environment. To learn and understand. It's only a SELECT.
It's only giving answers on how CBO will behave or, in other words, how CBO will respond to a solution to a requirement.
Developers who want to avoid trouble after developing should be aware of this, be able to understand it and use it.
On a development environment a developer needs to be able to check how his/her queries/program works out like predicted/modeled. Access to V$ views is will help.
If he/she doesn't do anything with it/insn't allowed to use it...OK, that's fine, we'll re-evaluate when we're in production...when all goes wrong...then the developer is the fan that has spread some s**t...and we'll have to pump in another bunch of $.
I think that the fact the majority of developers who aren't allowed (by grants or privileges) to measure and test their solutions, is the same majority looking for/in search of/believing in/been told of *'Silver Bullets'*, which don't exist.
Through time a lot of people have come to the conclusion: it depends.
You need to test and measure, on your development schema.
But anyway:
v$instance is a bit of 'a strange duck in the pond' in that context ;)
