BinaryDelta |
buildBinaryDelta(byte[] byOld,
byte[] byNew)
Builds a delta file (BinaryDelta) representing the difference
between the two byte arrays such that byNew can be reconstructed
using just the BinaryDelta constructed here and byOld. |

throws InvalidSourceException,

- Builds a delta file (BinaryDelta) representing the difference
between the two byte arrays such that byNew can be reconstructed
using just the BinaryDelta constructed here and byOld.
- Parameters:
byOld
- -- an array of all the bytes in the "old" file version.byNew
- -- an array of all the bytes in the new file version.
- Returns:
- a BinaryDelta object, that encapsulates the differences between
the two versions.
- Throws:
InvalidSourceException
- -- if there is a problem with one of the
two source byte arrays.
EndOfSourceException
- -- if the end of one of the source files is
hit unexpectedly. Actually, I don't think this should ever be thrown.
matchCurrentChunks
private BuildDelta.MatchChunksResult matchCurrentChunks(ByteArrayChunkCompare oNewChunk,
ByteArrayChunkCompare oOldChunk,
BuildDelta.SearchRange oNewRange,
BuildDelta.SearchRange oOldRange)
throws EndOfSourceException
- Note that the purpose of oTemp01 and oTemp02 is to avoid unnecessary
object instantiation. oTemp01 and oChunk01 should point to the same byte
array and so should oTemp02 adn oChunk02. Basically, this method
searches all oTemp01 for a match of current chunk in oChunk02 and vice versa.
