Imports

java.io.OutputStream

Output stream writing bytes into an underlying blocked byte array.

Field Summary

Modifier and Type	Field and Description
private long	pos The current position of the stream.
private BlockedByteArray	src The underlying destination.

Constructor Summary

Access	Constructor and Description
public	BlockedByteArrayOutputStream(BlockedByteArray the underlying blocked byte array src, long the initial position of stream pos) Creates a new stream writing data into the specified blocked byte array.

Method Summary

Modifier and Type	Method and Description
public void	close() Overrides java.io.OutputStream.close. Implements java.io.Closeable.close. Closes the stream.
pack-priv long	Returns: The current byte position. getPosition() Returns the current position.
pack-priv void	setPosition(long the new byte position newPos) Sets the position.
public void	write(int the byte to write b) Implements abstract java.io.OutputStream.write. Writes the single byte into the underlying blocked byte array.
public void	write(byte[] source byte array buf, int index of the first byte to write offset, int the number of bytes to write len) Overrides java.io.OutputStream.write. Writes the specified bytes into the underlying blocked byte array.

Inherited from java.io.OutputStream:: flush nullOutputStream write
