Class SVNDeltaProcessor

public void applyTextDelta(File baseFile,
                           File targetFile,
                           boolean computeCheksum)
            throws SVNException

Starts processing deltas given a base file and a one to write resultant target bytes to.

If a target full text is a newly added file (text deltas would be vs. empty), then source bytes are not needed and baseFile may be passed as null.

If a file represented by targetFile does not exist yet, first tries to create an empty file.

If computeChecksum is true, then an MD5 checksum will be calculated for target bytes. The calculated checksum is returned by textDeltaEnd().

Parameters:

baseFile - a base file to read base file contents from

targetFile - a destination file where resultant target bytes will be written

computeCheksum - true to calculate checksum

Throws:

SVNException -

public void applyTextDelta(InputStream base,
                           OutputStream target,
                           boolean computeCheksum)

Starts processing deltas given a base file stream and an output stream to write resultant target bytes to.

If a target full text is a newly added file (text deltas would be vs. empty), then source bytes are not needed and base may be passed as null.

If computeChecksum is true, then an MD5 checksum will be calculated for target bytes. The calculated checksum is returned by textDeltaEnd().

Parameters:

base - an input stream to take base file contents from

target - an output stream to write the resultant target contents to

computeCheksum - true to calculate checksum

public OutputStream textDeltaChunk(SVNDiffWindow window)
            throws SVNException

Receives a next diff window to be applied. The return value is a dummy stream (left for backward compatibility) since new data should come within a diff window.

Parameters:

window - a diff window

Returns:

a dummy output stream

Throws:

SVNException -
