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

|---|---|
int |
available()
Returns available space in the buffer.
|
int |
capacity()
Returns total capacity of the buffer

Return length data stored in the buffer
|
void |
write(byte[] b,
int off,
int len,
OutputStream outputStream)
Writes
len bytes from the specified byte array
starting at offset off to this session buffer. |
void |
write(byte[] b,
OutputStream outputStream)
Writes
b.length bytes from the specified byte array
to this session buffer. |
void |
write(int b,
OutputStream outputStream)
Writes the specified byte to this session buffer.
|
void |
writeLine(CharArrayBuffer charbuffer,
OutputStream outputStream)
Writes characters from the specified char array followed by a line
delimiter to this session buffer.

metrics - HTTP transport metrics.bufferSize - buffer size. Must be a positive number.fragmentSizeHint - 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(int bufferSize)

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.
