Hi,

I wanted to know how we can implement the functionaity of
Compressing/decompressing(Chunking)the java code physically like how it is
done in Eclipse.

In Eclipse we have a small button to the left and when we click on that,
the code compresses/decompresses.I wanted to implement such a
functionality in my application wherein i am able to do the same for my
files.

Thanks in advance
Nita

The help describes it as 'collapse/expand' rather than 'compress/decompress' but anyway...

This is handled in Eclipse with something called a ProjectionViewer. Have a butchers at http://help.eclipse.org/help30/topic/org.eclipse.platform.do c.isv/reference/api/org/eclipse/jface/text/source/projection /ProjectionViewer.html

It's a subtype of SourceViewer, which is a subtype of TextViewer, which is what you might be using at the moment. This is currently subtyped by JavaSourceViewer in the org.eclipse.jdt.internal.ui.javaeditor package if you want to see how it is used. (plugin org.eclipse.jdt.ui)

Do you mean tree functionality? If you do, take a look at the Tree and
TreeViewer classes.
Because I don't think Java code is compressed/decompressed by Eclipse
(physically or any other way).
