Class ByteArrayOutputBuffer

java.lang.Object
  java.io.OutputStream
      com.github.libxjava.io.ByteArrayOutputBuffer

All Implemented Interfaces:

Closeable, Flushable

public final class ByteArrayOutputBuffer
extends OutputStream

This implementation is like the ByteArrayOutputStream but not synchronised and it lets the user optimise byte array allocation. Furthermore this type of OutputStream is not closable, so it can be reused.

Version:

libxjava-jse5 - 0.2

Method Detail

getByteArrayReference

public byte[] getByteArrayReference()

Returns the reference to this buffer's byte array.

Remember that calling reset() only resets the internal counter. If you do not want any changes in the byte array obtained by this method, you need to call resetNew() or resetNew(int)!

toByteArray

public byte[] toByteArray()

reset

public void reset()

resetNew

public void resetNew()

Replaces the internal buffer with a new byte array of size 16. Call of this method equals resetNew(16)

resetNew

public void resetNew(int size)

Replaces the internal buffer with a new byte array of size size.

Parameters:

size -

setOutput

public void setOutput(byte[] buffer,
                      int off)

Resets the internal buffer with the specified byte array and initialises the internal write pointer to off.

Parameters:

buffer -

off -

size

public int size()

close

public void close()

This type of outputstream is not closable.

Specified by:

close in interface Closeable

Overrides:

write

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

Overrides:

write in class OutputStream

write

public void write(int b)

Specified by:
