Batch source modifications [message #39134]

I need to make several modifications of source of ICompilationUnit,
but want to be able to Undo them later as one modification.
Currently I use following method:
ICompilationUnit wc = (ICompilationUnit) getCompilationUnit();
IBuffer buffer = wc.getBuffer();
buffer.replace(start, length, sourcePart);
buffer.replace(start2, length2, sourcePart2);
...etc

How to change this code?

Buffers do not support batching, but maybe you could perform all your
changes on a copy of the buffer contents, and set it all at once.

Hello Konstantin,

there are working copies for ICompilationUnit's
(ICompilationUnit.getWorkingCopy()).
Maybe they will fit your needs.

Thanks.
For big files this produces big overhead...
Ok, I think, I can optimize it by finding minimal range...

Maybe you could log a feature request, I know that some buffer
implementation are able to deal with multi-edits, we may want to leverage
this into our API.
