JdkZlibDecoder

public JdkZlibDecoder()

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

JdkZlibDecoder

public JdkZlibDecoder(int maxAllocation)

Creates a new instance with the default wrapper (ZlibWrapper.ZLIB) and the specified maximum buffer allocation.

参数:

maxAllocation - Maximum size of the decompression buffer. Must be >= 0. If zero, maximum size is decided by the ByteBufAllocator.

JdkZlibDecoder

public JdkZlibDecoder(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.

JdkZlibDecoder

public JdkZlibDecoder(byte[] dictionary,
                      int maxAllocation)

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

参数:

maxAllocation - Maximum size of the decompression buffer. Must be >= 0. If zero, maximum size is decided by the ByteBufAllocator.

JdkZlibDecoder

public JdkZlibDecoder(ZlibWrapper wrapper)

Creates a new instance with the specified wrapper. Be aware that only ZlibWrapper.GZIP, ZlibWrapper.ZLIB and ZlibWrapper.NONE are supported atm.

JdkZlibDecoder

public JdkZlibDecoder(ZlibWrapper wrapper,
                      int maxAllocation)

Creates a new instance with the specified wrapper and maximum buffer allocation. Be aware that only ZlibWrapper.GZIP, ZlibWrapper.ZLIB and ZlibWrapper.NONE are supported atm.

参数:

maxAllocation - Maximum size of the decompression buffer. Must be >= 0. If zero, maximum size is decided by the ByteBufAllocator.

JdkZlibDecoder

public JdkZlibDecoder(ZlibWrapper wrapper,
                      boolean decompressConcatenated)

JdkZlibDecoder

public JdkZlibDecoder(ZlibWrapper wrapper,
                      boolean decompressConcatenated,
                      int maxAllocation)

                      int maxAllocation)

方法详细资料

isClosed

public boolean isClosed()

从类复制的说明: ZlibDecoder

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

指定者:

isClosed 在类中 ZlibDecoder

decode

protected void decode(ChannelHandlerContext ctx,
                      ByteBuf in,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

从类复制的说明: ByteToMessageDecoder

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

指定者:

decode 在类中 ByteToMessageDecoder

参数:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

抛出:

java.lang.Exception - is thrown if an error occurs

decompressionBufferExhausted

protected void decompressionBufferExhausted(ByteBuf buffer)

从类复制的说明: ZlibDecoder

Called when the decompression buffer cannot be expanded further. Default implementation is a no-op, but subclasses can override in case they want to do something before the DecompressionException is thrown, such as log the data that was decompressed so far.

覆盖:

decompressionBufferExhausted 在类中 ZlibDecoder

handlerRemoved0

protected void handlerRemoved0(ChannelHandlerContext ctx)
                        throws java.lang.Exception

从类复制的说明: ByteToMessageDecoder

Gets called after the ByteToMessageDecoder was removed from the actual context and it doesn't handle events anymore.

覆盖:

handlerRemoved0 在类中 ByteToMessageDecoder

抛出:

java.lang.Exception
