所有已实现的接口:

ChannelHandler, ChannelInboundHandler

public class CompatibleMarshallingDecoder
extends ReplayingDecoder<java.lang.Void>

ReplayingDecoder which use an Unmarshaller to read the Object out of the ByteBuf. If you can you should use MarshallingDecoder.

构造器详细资料

CompatibleMarshallingDecoder

public CompatibleMarshallingDecoder(UnmarshallerProvider provider,
                            int maxObjectSize)

Create a new instance of CompatibleMarshallingDecoder.

参数:

provider - the UnmarshallerProvider which is used to obtain the Unmarshaller for the Channel

maxObjectSize - the maximal size (in bytes) of the Object to unmarshal. Once the size is exceeded the Channel will get closed. Use a a maxObjectSize of Integer.MAX_VALUE to disable this. You should only do this if you are sure that the received Objects will never be big and the sending side are trusted, as this opens the possibility for a DOS-Attack due an OutOfMemoryError.

方法详细资料

decode

protected void decode(ChannelHandlerContext ctx,
          ByteBuf buffer,
          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

buffer - 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

decodeLast

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

从类复制的说明: ByteToMessageDecoder

Is called one last time when the ChannelHandlerContext goes in-active. Which means the ByteToMessageDecoder.channelInactive(ChannelHandlerContext) was triggered. By default this will just call ByteToMessageDecoder.decode(ChannelHandlerContext, ByteBuf, List) but sub-classes may override this for some special cleanup operation.

覆盖:

decodeLast 在类中 ByteToMessageDecoder

抛出:

java.lang.Exception

exceptionCaught

public void exceptionCaught(ChannelHandlerContext ctx,
                   java.lang.Throwable cause)
                     throws java.lang.Exception

从类复制的说明: ChannelInboundHandlerAdapter

Calls ChannelHandlerContext.fireExceptionCaught(Throwable) to forward to the next ChannelHandler in the ChannelPipeline. Sub-classes may override this method to change behavior.

指定者:

exceptionCaught 在接口中 ChannelHandler

指定者:

exceptionCaught 在接口中 ChannelInboundHandler

覆盖:

exceptionCaught 在类中 ChannelInboundHandlerAdapter

抛出:

java.lang.Exception
