ByteBufferOutputStream

public ByteBufferOutputStream()

Creates a new byte buffer output stream.

Method Detail

getBuffer

public ByteBuffer getBuffer()

Returns a reference to the underlying buffer.

flip

public ByteBuffer flip()

Flips and returns the buffer. The returned buffer will have a position of zero and a limit equal to the number of bytes written. Call reset() to reset the buffer before writing again.

reset

public void reset()

Resets our internal buffer.

write

public void write(int b)

Specified by:

write in class OutputStream

write

public void write(byte[] b,
                  int off,
                  int len)

Overrides:

write in class OutputStream

expand

protected final void expand(int needed)

Expands our buffer to accomodate the specified capacity.
