Constructor Details

GZipContentEncoding

public GZipContentEncoding()

Construct GZipContentEncoding using default buffer sizes.

GZipContentEncoding

public GZipContentEncoding(int inBufferSize,
 int outBufferSize)

Construct GZipContentEncoding using specific buffer sizes.

Parameters:

inBufferSize - input buffer size

outBufferSize - output buffer size

GZipContentEncoding

public GZipContentEncoding(int inBufferSize,
 int outBufferSize,
 EncodingFilter encoderFilter)

Construct GZipContentEncoding using specific buffer sizes, with default compression level and strategy.

Parameters:

inBufferSize - input buffer size

outBufferSize - output buffer size

encoderFilter - EncodingFilter, which will decide if GZipContentEncoding should be applied to encode specific HttpHeader packet.

GZipContentEncoding

public GZipContentEncoding(int inBufferSize,
 int outBufferSize,
 int compressionLevel,
 int compressionStrategy,
 EncodingFilter encoderFilter)
