Constructor Detail

JZlibDecoder

public JZlibDecoder()

Creates a new instance with the default wrapper (ZlibWrapper.ZLIB).

Throws:

CompressionException - if failed to initialize zlib

JZlibDecoder

public JZlibDecoder(ZlibWrapper wrapper)

Creates a new instance with the specified wrapper.

Throws:

CompressionException - if failed to initialize zlib

JZlibDecoder

public JZlibDecoder(byte[] dictionary)

Creates a new instance with the specified preset dictionary. The wrapper is always ZlibWrapper.ZLIB because it is the only format that supports the preset dictionary.

Throws:

CompressionException - if failed to initialize zlib

Method Detail

isClosed

public boolean isClosed()

Returns true if and only if the end of the compressed stream has been reached.

Specified by:

isClosed in class ZlibDecoder

decode

protected void decode(io.netty.channel.ChannelHandlerContext ctx,
          io.netty.buffer.ByteBuf in,
          io.netty.buffer.ByteBuf out)
               throws Exception

Description copied from class: ByteToByteDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read anymore or till nothing was read from the input ByteBuf.

Specified by:

decode in class ByteToByteDecoder

Parameters:

ctx - the ChannelHandlerContext which this ByteToByteDecoder belongs to

in - the ByteBuf from which to read data

out - the ByteBuf to which the decoded data will be written

Throws:

Exception - is thrown if an error accour
