 org.gjt.sp.jedit.textarea.BufferHandler
| BufferHandler | | class BufferHandler implements BufferListener(Code) | | Note that in this class we take great care to defer complicated
calculations to the end of the current transaction if the buffer
informs us a compound edit is in progress
(isTransactionInProgress()).
This greatly speeds up replace all for example, by only doing certain
things once, particularly in moveCaretPosition().
Try doing a replace all in a large file, for example. It is very slow
in 3.2, faster in 4.0 (where the transaction optimization was
introduced) and faster still in 4.1 (where it was further improved).
There is still work to do; see TODO.txt.
