Method Detail

doCompress

protected abstract byte[] doCompress(byte[] payload)
                              throws IOException

Implement this method to do the actual work of compressing the payload

Parameters:

payload - the bytes to compress

Returns:

the compressed bytes

Throws:

IOException - if the compression causes an IOException

compress

public final byte[] compress(byte[] payload)

Asserts that payload is not null and calls doCompress

Specified by:

compress in interface CompressionCodec

Parameters:

payload - bytes to compress

Returns:

compressed bytes

Throws:

CompressionException - if doCompress throws an IOException

decompress

public final byte[] decompress(byte[] compressed)

Asserts the compressed bytes is not null and calls doDecompress

Specified by:

decompress in interface CompressionCodec

Parameters:

compressed - compressed bytes

Returns:

decompressed bytes

Throws:

CompressionException - if doDecompress throws an IOException

doDecompress

protected abstract byte[] doDecompress(byte[] compressed)
                                throws IOException

Implement this method to do the actual work of decompressing the compressed bytes.

Parameters:

compressed - compressed bytes

Returns:

decompressed bytes

Throws:

IOException - if the decompression runs into an IO problem
