protected byte[] buffer()
ObjectInserterThis buffer is supplied by the ObjectInserter base class to itself and its subclasses for the purposes of pulling data from a supplied InputStream, passing it through a Deflater, or formatting the canonical format of a small object like a small tree or commit.
This buffer IS NOT for translation such as auto-CRLF or content filtering and must not be used for such purposes.
The returned buffer is small, around a few KiBs, and the size may change between versions of JGit. Callers using this buffer must always check the length of the returned array to ascertain how much space was provided.
There is a single buffer for each ObjectInserter, repeated calls to this method will (usually) always return the same buffer. If the caller needs more than one buffer, or needs a buffer of a larger size, it must manage that buffer on its own.
The buffer is usually on first demand for a buffer.

ObjectInserter
The returned reader allows the calling thread to read back recently
inserted objects without first calling flush() to make them
visible to the repository. The returned reader should only be used from
the same thread as the inserter. Objects written by this inserter may not
be visible to this.newReader().newReader().

ObjectInserterThe flush may take some period of time to make the objects available to other threads.
flush in class ObjectInserterIOException - the flush could not be completed; objects inserted thus far
are in an indeterminate state.public void release()
ObjectInserterAn inserter that has been released can be used again, but may need to be released after the subsequent usage.
