java.lang.Objectorg.tmatesoft.svn.core.io.diff.SVNDeltaGenerator
The SVNDeltaGenerator is intended for generating diff windows of fixed size having a target version of a file against a source one. File contents are provided as two streams - source and target ones, or just target if delta is generated against empty contents.
The generator uses the V-Delta algorithm for generating full contents delta (vs. empty) and the X-Delta algorithm for generating delta as a difference between target and non-empty source streams.
Constructor Summary | |
SVNDeltaGenerator()
Creates a generator that will produce diff windows of 100Kbytes contents length. |
|
SVNDeltaGenerator(int maximumDiffWindowSize)
Creates a generator that will produce diff windows of a specified contents length. |

sendDelta(String path,

Generates a series of diff windows of fixed size comparing target bytes (from target stream) against an
empty file and sends produced windows to the provided
consumer. |

Generates a series of diff windows of fixed size comparing target bytes (read from target stream) against source
bytes (read from source stream), and sends produced windows to the provided
consumer. |

ignored (if it's null) or immediately closed

the return value will be a strig containing a hex representation
of the MD5 digest computed for the target contents.
