public final class FastByteArrayOutputStream
extends ByteArrayOutputStream

An unsynchronized ByteArrayOutputStream implementation. This version also has a constructor that lets you create a stream with initial content.

Field Detail

maxGrowSize

protected int maxGrowSize

Max grow size (unless if writing more than this amount of bytes)

Constructor Detail

FastByteArrayOutputStream

public FastByteArrayOutputStream(int pSize)

Creates a ByteArrayOutputStream with the given initial buffer size.

Parameters:

pSize - initial buffer size

FastByteArrayOutputStream

public FastByteArrayOutputStream(byte[] pBuffer)

Creates a ByteArrayOutputStream with the given initial content.

Note that the buffer is not cloned, for maximum performance.

Parameters:

pBuffer - initial buffer

Method Detail

write

public void write(byte[] pBytes,
                  int pOffset,
                  int pLength)

Overrides:

write in class ByteArrayOutputStream

write

public void write(int pByte)

Overrides:

write in class ByteArrayOutputStream

writeTo

public void writeTo(OutputStream pOut)
             throws IOException

Overrides:

writeTo in class ByteArrayOutputStream

Throws:

IOException

toByteArray

public byte[] toByteArray()

Overrides:

toByteArray in class ByteArrayOutputStream

createInputStream

public ByteArrayInputStream createInputStream()

Creates a ByteArrayInputStream that reads directly from this FastByteArrayOutputStream's byte buffer. The buffer is not cloned, for maximum performance.

Note that care needs to be taken to avoid writes to this output stream after the input stream is created. Failing to do so, may result in unpredictable behaviour.

Returns:

a new ByteArrayInputStream, reading from this stream's buffer.
