NoopCompressor

public NoopCompressor()

Method Detail

algorithm

public String algorithm()

Description copied from interface: Compressor

The name of the algorithm used.

It's the string that will be used in the STARTUP message. Null or empty means no compression.

Specified by:

algorithm in interface Compressor<B>

compress

public B compress(B uncompressed)

Description copied from interface: Compressor

Compresses a payload using the "legacy" format of protocol v4- frame bodies.

The resulting payload encodes the uncompressed length, and is therefore self-sufficient for decompression.

Specified by:

compress in interface Compressor<B>

decompress

public B decompress(B compressed)

Description copied from interface: Compressor

Decompresses a payload that was compressed with Compressor.compress(Object).

Specified by:

decompress in interface Compressor<B>

compressWithoutLength

public B compressWithoutLength(B uncompressed)

Description copied from interface: Compressor

Compresses a payload using the "modern" format of protocol v5+ segments.

The resulting payload does not encode the uncompressed length. It must be stored separately, and provided to the decompression method.

Specified by:

compressWithoutLength in interface Compressor<B>

decompressWithoutLength

public B decompressWithoutLength(B compressed,
                                 int uncompressedLength)

Description copied from interface: Compressor

Decompresses a payload that was compressed with Compressor.compressWithoutLength(Object).

Specified by:

decompressWithoutLength in interface Compressor<B>
