AbstractCompressionCodec

public AbstractCompressionCodec()

方法详细资料

doCompress

protected abstract byte[] doCompress(byte[] payload)
                              throws java.io.IOException

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

参数:

payload - the bytes to compress

返回:

the compressed bytes

抛出:

java.io.IOException - if the compression causes an IOException

compress

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

Asserts that payload is not null and calls doCompress

指定者:

compress 在接口中 CompressionCodec

参数:

payload - bytes to compress

返回:

compressed bytes

抛出:

CompressionException - if doCompress throws an IOException

decompress

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

Asserts the compressed bytes is not null and calls doDecompress

指定者:

decompress 在接口中 CompressionCodec

参数:

compressed - compressed bytes

返回:

decompressed bytes

抛出:

CompressionException - if doDecompress throws an IOException

doDecompress

protected abstract byte[] doDecompress(byte[] compressed)
                                throws java.io.IOException

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

参数:

compressed - compressed bytes

返回:

decompressed bytes

抛出:

java.io.IOException - if the decompression runs into an IO problem
