Defines common contract for clients interested in folding processing.

Method Summary

Modifier and Type	Method and Description
default void	beforeFoldRegionRemoved(FoldRegion region) Informs that the given fold region is about to be removed.

default void	onFoldRegionStateChange(FoldRegion region) Informs that 'collapsed' state of given fold region is just changed, or that the given fold region has just been created.

Method Detail

onFoldRegionStateChange

default void onFoldRegionStateChange(FoldRegion region)

Informs that 'collapsed' state of given fold region is just changed, or that the given fold region has just been created.

Note: listener should delay fold region state processing until onFoldProcessingEnd() is called. I.e. folding model may return inconsistent data between current moment and onFoldProcessingEnd().

Parameters:

region - fold region that is just collapsed or expanded

beforeFoldRegionRemoved

default void beforeFoldRegionRemoved(FoldRegion region)

Informs that the given fold region is about to be removed.

onFoldProcessingEnd

default void onFoldProcessingEnd()

Informs that fold processing is done.
