Class OpenBufferOutputStream

java.lang.Object

java.io.OutputStream

java.io.ByteArrayOutputStream

com.sun.jbi.messaging.util.OpenBufferOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class OpenBufferOutputStream
extends ByteArrayOutputStream

Special version of ByteArrayOutputStream which allows direct access to the underlying byte buffer. If left on it's own, BAOS will copy the entire buffer every time you access it. Basically, we lose a bit a safety in order to gain a ton of performance. So be careful!

Constructor Detail

OpenBufferOutputStream

public OpenBufferOutputStream()

Initializes a new buffer stream.

OpenBufferOutputStream

public OpenBufferOutputStream(int size)

Initializes a new buffer stream, with the specified buffer size.

Parameters:

size - initial size of the buffer.

Method Detail

getBuffer

public byte[] getBuffer()

Retrieves the raw byte buffer underneath the covers.

Returns:

raw bytes underlying the buffer.

getCount

public int getCount()

Returns the valid number of bytes written to the buffer.

Returns:

number of valid bytes in the buffer.

asInputStream

public InputStream asInputStream()

Utility method used to create an appropriately sized stream based off of the underlying buffer. The stream is clipped to size, so it will not contain any garbage bytes from the end of the buffer.

Returns:

input stream pointing to bytes in the buffer
