      org.apache.activemq.transport.nio.NIOOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, TimeStampStream

public class NIOOutputStream
extends java.io.OutputStream
implements TimeStampStream

An optimized buffered outputstream for Tcp

Constructor Summary

NIOOutputStream(java.nio.channels.WritableByteChannel out)
Constructor

NIOOutputStream(java.nio.channels.WritableByteChannel out, int size)
Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Method Summary

protected void	checkClosed() Checks that the stream has not been closed
void	close() close this stream
void	flush() flush the data to the output stream This doesn't call flush on the underlying outputstream, because Tcp is particularly efficent at doing this itself ....
long	getWriteTimestamp()
boolean	isWriting()
void	setEngine(javax.net.ssl.SSLEngine engine)
void	write(byte[] b, int off, int len) write a byte array to the stream
protected void	write(java.nio.ByteBuffer data)
void	write(int b) write a byte on to the stream

NIOOutputStream

public NIOOutputStream(java.nio.channels.WritableByteChannel out,
                       int size)

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Parameters:

out - the underlying output stream.

size - the buffer size.

Throws:

java.lang.IllegalArgumentException - if size <= 0.

Method Detail

write

public void write(int b)
           throws java.io.IOException

write a byte on to the stream

Specified by:

write in class java.io.OutputStream

Parameters:

b - - byte to write

Throws:

java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

write a byte array to the stream

Overrides:

write in class java.io.OutputStream

Parameters:

b - the byte buffer

off - the offset into the buffer

len - the length of data to write

Throws:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

flush the data to the output stream This doesn't call flush on the underlying outputstream, because Tcp is particularly efficent at doing this itself ....

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException

close

public void close()

java.io.IOException

checkClosed

protected void checkClosed()
                    throws java.io.IOException

Checks that the stream has not been closed

Throws:

java.io.IOException
