Field Summary

LinkedBuffer	head The main/root/head buffer of this write session.
int	nextBufferSize The next buffer size used when growing the buffer.
java.io.OutputStream	out The sink of this buffer.
WriteSink	sink The sink of this write session.
protected int	size The actual number of bytes written to the buffer.
protected LinkedBuffer	tail The last buffer of this write session (This points to head if growing not needed).

Constructor Summary

WriteSession(LinkedBuffer head)

WriteSession(LinkedBuffer head, int nextBufferSize)

WriteSession(LinkedBuffer head, java.io.OutputStream out)

Method Summary

WriteSession	clear() The buffer will be cleared (tail will point to the head) and the size will be reset to zero.
int	getSize() Returns the amount of bytes written in this session.
byte[]	toByteArray() Returns a single byte array containg all the contents written to the buffer(s).
