 org.apache.mina.filter.compression.Zlib
| Zlib | | class Zlib (Code) | | A helper class for interfacing with the JZlib library. This class acts both
as a compressor and decompressor, but only as one at a time. The only
flush method supported is Z_SYNC_FLUSH also known as Z_PARTIAL_FLUSH

| Constructor Summary | |
| public | Zlib(int compressionLevel, int mode)
Parameters:
compressionLevel - the level of compression that should be used
Parameters:
mode - the mode in which the instance will operate. |
| COMPRESSION_DEFAULT | | final public static int COMPRESSION_DEFAULT(Code) | | |
| COMPRESSION_MAX | | final public static int COMPRESSION_MAX(Code) | | |

| Zlib | | public Zlib(int compressionLevel, int mode)(Code) | |
Parameters:
compressionLevel - the level of compression that should be used
Parameters:
mode - the mode in which the instance will operate. Can be eitherof MODE_DEFLATER or MODE_INFLATER |
| cleanUp | | public void cleanUp()(Code) | | Cleans up the resources used by the compression library.
|
| deflate | | public IoBuffer deflate(IoBuffer inBuffer) throws IOException(Code) | |
Parameters:
inBuffer - the buffer to be compressed. The contents are transferredinto a local byte array and the buffer is flipped and returned intact. the buffer with the compressed data
throws:
IOException - if the compression of teh buffer failed for some reason |
| inflate | | public IoBuffer inflate(IoBuffer inBuffer) throws IOException(Code) | |
Parameters:
inBuffer - the IoBuffer to be decompressed. The contentsof the buffer are transferred into a local byte array and the buffer isflipped and returned intact. the decompressed data
throws:
IOException - if the decompression of the data failed for some reason. |
