Method Detail

writeImpl

protected void writeImpl()
                  throws java.io.IOException

Writes the index file to PackIndexWriter.out.

Implementations should go something like:

 writeFanOutTable();
 for (final PackedObjectInfo po : entries)
        writeOneEntry(po);
 writeChecksumFooter();
 

Where the logic for writeOneEntry is specific to the index format in use. Additional headers/footers may be used if necessary and the PackIndexWriter.entries collection may be iterated over more than once if necessary. Implementors therefore have complete control over the data.

Specified by:

writeImpl in class PackIndexWriter

Throws:

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

writeObjectNames

private void writeObjectNames()
                       throws java.io.IOException

Throws:

                throws java.io.IOException
