类 ObjectEncoder

java.lang.Object

org.jboss.netty.handler.codec.oneone.OneToOneEncoder

org.jboss.netty.handler.codec.serialization.ObjectEncoder

所有已实现的接口:

ChannelDownstreamHandler, ChannelHandler

@ChannelHandler.Sharable
public class ObjectEncoder
extends OneToOneEncoder

An encoder which serializes a Java object into a ChannelBuffer.

Please note that the serialized form this encoder produces is not compatible with the standard ObjectInputStream. Please use ObjectDecoder or ObjectDecoderInputStream to ensure the interoperability with this encoder.

构造器详细资料

ObjectEncoder

public ObjectEncoder()

Creates a new encoder with the estimated length of 512 bytes.

ObjectEncoder

public ObjectEncoder(int estimatedLength)

Creates a new encoder.

参数:

estimatedLength - the estimated byte length of the serialized form of an object. If the length of the serialized form exceeds this value, the internal buffer will be expanded automatically at the cost of memory bandwidth. If this value is too big, it will also waste memory bandwidth. To avoid unnecessary memory copy or allocation cost, please specify the properly estimated value.

encode

protected java.lang.Object encode(ChannelHandlerContext ctx,
                      Channel channel,
                      java.lang.Object msg)
                           throws java.lang.Exception

从类复制的说明: OneToOneEncoder

Transforms the specified message into another message and return the transformed message. Note that you can not return null, unlike you can in OneToOneDecoder.decode(ChannelHandlerContext, Channel, Object); you must return something, at least ChannelBuffers.EMPTY_BUFFER.

指定者:

encode 在类中 OneToOneEncoder

抛出:

java.lang.Exception
