textDeltaChunk
public java.io.OutputStream textDeltaChunk(java.lang.String path, SVNDiffWindow diffWindow) throws SVNException Description copied from interface:ISVNDeltaConsumer
Collects a next delta chunk. The return type is nomore relevant and is left only for backward compatibility. So, the return value may be just null. Otherwise if it's not null, the stream will be immediately closed.If there are more than one windows for the file, this method is called several times.
- Specified by:
textDeltaChunk
in interfaceISVNDeltaConsumer
- Parameters:
path
- a file path relative to the edit root directorydiffWindow
- a next diff window- Returns:
- an output stream
- Throws:
SVNException
-
textDeltaEnd
Description copied from interface:ISVNDeltaConsumer
Finalizes collecting text delta(s).- Specified by:
textDeltaEnd
in interfaceISVNDeltaConsumer
- Parameters:
path
- a file path relative to the edit root directory- Throws:
SVNException
-
applyTextDelta
public void applyTextDelta(java.lang.String path, java.lang.String baseChecksum) throws SVNException Description copied from interface:ISVNDeltaConsumer
Starts applying text delta(s) to an opened file.- Specified by:
applyTextDelta
in interfaceISVNDeltaConsumer
- Parameters:
path
- a file path relative to the edit root directorybaseChecksum
- an MD5 checksum for the base file contents (before the file is changed)- Throws:
SVNException
- if the calculated base file checksum didn't match the expectedbaseChecksum
