Method Detail

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 interface ISVNDeltaConsumer

Parameters:

path - a file path relative to the edit root directory

baseChecksum - 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 expected baseChecksum

applyText

public void applyText(java.lang.String path)
               throws SVNException

Throws:

SVNException

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 interface ISVNDeltaConsumer

Parameters:

path - a file path relative to the edit root directory

diffWindow - a next diff window

Returns:

an output stream

Throws:

SVNException

textDeltaEnd

public void textDeltaEnd(java.lang.String path)
                  throws SVNException

Description copied from interface: ISVNDeltaConsumer

Finalizes collecting text delta(s).

Specified by:

textDeltaEnd in interface ISVNDeltaConsumer

Parameters:

path - a file path relative to the edit root directory

Throws:

SVNException

close

public void close()
           throws SVNException

Throws:
