public class SessionOutputBufferImpl extends Object implements SessionOutputBuffer, BufferInfo
OutputStream. This class buffers small chunks of
output data in an internal byte array for optimal output performance.
writeLine(CharArrayBuffer) and writeLine(String) methods
of this class use CR-LF as a line delimiter.

metrics - HTTP transport metrics.bufferSize - buffer size. Must be a positive number.fragementSizeHint - fragment size hint defining a minimal size of a fragment
that should be written out directly to the socket bypassing the session buffer.
Value 0 disables fragment buffering.charEncoder - charEncoder to be used for encoding HTTP protocol elements.
If null simple type cast will be used for char to byte conversion.public SessionOutputBufferImpl(HttpTransportMetricsImpl metrics, int bufferSize)

SessionOutputBufferflush is
that calling it is an indication that, if any bytes previously
written have been buffered by the implementation of the output
stream, such bytes should immediately be written to their
intended destination.flush in interface SessionOutputBufferIOException - if an I/O error occurs.public void write(byte[] b,

throws IOException
SessionOutputBufferlen bytes from the specified byte array
starting at offset off to this session buffer.
If off is negative, or len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is thrown.
