PackBitmapIndexWriterV1

public PackBitmapIndexWriterV1(java.io.OutputStream dst)

Creates the version 1 pack bitmap index files.

Parameters:

dst - the output stream to which the index will be written.

Method Detail

write

public void write(PackBitmapIndexBuilder bitmaps,
                  byte[] packDataChecksum)
           throws java.io.IOException

Write all object entries to the index stream.

After writing the stream passed to the factory is flushed but remains open. Callers are always responsible for closing the output stream.

Parameters:

bitmaps - the index data for the bitmaps

packDataChecksum - checksum signature of the entire pack data content. This is traditionally the last 20 bytes of the pack file's own stream.

Throws:

java.io.IOException - an error occurred while writing to the output stream, or this index format cannot store the object data supplied.

writeHeader

private void writeHeader(int options,
                         int bitmapCount,
                         byte[] packDataChecksum)
                  throws java.io.IOException

Throws:

java.io.IOException

writeBody

private void writeBody(PackBitmapIndexBuilder bitmaps)
                throws java.io.IOException

Throws:
