isFlushed

public final boolean isFlushed()

flush

public final int flush(byte[] output,
 int offset,
 int length)

Flushes the pending buffer into the given output array. If the output array is to small, only a partial flush is done.

Parameters:

output - the output array;

offset - the offset into output array;

length - the maximum number of bytes to store;

Throws:

IndexOutOfBoundsException - if offset or length are invalid.

toByteArray

public final byte[] toByteArray()

Flushes the pending buffer and returns that data in a new array

Parameters:

output - the output stream
