Constructor Detail

PerMessageDeflateDecoder

public PerMessageDeflateDecoder(boolean noContext,
                                int minInflateBound)

Constructs a per-message deflate decoder with specified context takeover control and minimum upper bound on the decompressed size.

Parameters:

noContext - true to prevent from using the context takeover

minInflateBound - determines the minimum upper bound on the decompressed size. Setting this parameter to proper value may speed up the decompression of highly compressed data.

PerMessageDeflateDecoder

public PerMessageDeflateDecoder(boolean noContext)

Constructs a per-message deflate decoder with specified context takeover control.

Parameters:

noContext - true to prevent from using the context takeover
