Method Summary

abstract void	compress(java.nio.ByteBuffer inputBuffer, java.lang.Object object, java.nio.ByteBuffer outputBuffer) The compressor should read the input buffer from the current position to the limit, compress the data, and put the result in the output buffer.
abstract void	decompress(java.nio.ByteBuffer inputBuffer, java.lang.Class type, java.nio.ByteBuffer outputBuffer) The compressor should read the input buffer from the current position to the limit, decompress the data, and put the result in the output buffer.
<T> T	readObjectData(java.nio.ByteBuffer buffer, java.lang.Class<T> type) Reads an object from the buffer.
void	setCompress(boolean compress) Sets whether the compressor will compress data after serialization.
void	setDecompress(boolean decompress) Sets whether the compressor will decompress data before serialization.
void	writeObjectData(java.nio.ByteBuffer buffer, java.lang.Object object) Writes the object to the buffer.

Constructor Detail

Compressor

public Compressor(Serializer serializer)

Creates a compressor with compress and decompress set to true and bufferSize set to 2048.

Parameters:

serializer -

Compressor

public Compressor(Serializer serializer,
                  int bufferSize)

Parameters:

bufferSize - The maximum size in bytes of an object that can be read or written.

Method Detail

setCompress

public void setCompress(boolean compress)

Sets whether the compressor will compress data after serialization.

setDecompress

public void setDecompress(boolean decompress)

Sets whether the compressor will decompress data before serialization.

writeObjectData

public void writeObjectData(java.nio.ByteBuffer buffer,
                            java.lang.Object object)

Description copied from class: Serializer

Writes the object to the buffer.

Specified by:

writeObjectData in class Serializer

object - Cannot be null.

readObjectData

public <T> T readObjectData(java.nio.ByteBuffer buffer,
                            java.lang.Class<T> type)

Description copied from class: Serializer

Reads an object from the buffer.

Specified by:

readObjectData in class Serializer

Returns:

The deserialized object, never null.

compress

public abstract void compress(java.nio.ByteBuffer inputBuffer,
                              java.lang.Object object,
                              java.nio.ByteBuffer outputBuffer)

The compressor should read the input buffer from the current position to the limit, compress the data, and put the result in the output buffer.

Parameters:

outputBuffer - A non-direct buffer.

decompress

public abstract void decompress(java.nio.ByteBuffer inputBuffer,
                                java.lang.Class type,
                                java.nio.ByteBuffer outputBuffer)

The compressor should read the input buffer from the current position to the limit, decompress the data, and put the result in the output buffer.

Parameters:

outputBuffer - A non-direct buffer.
