Constructor Detail

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,
