Uses of ChannelDuplexHandler in io.netty.handler.traffic

Subclasses of ChannelDuplexHandler in io.netty.handler.traffic

Modifier and Type	Class	Description
class	AbstractTrafficShapingHandler	AbstractTrafficShapingHandler allows to limit the global bandwidth (see GlobalTrafficShapingHandler) or per session bandwidth (see ChannelTrafficShapingHandler), as traffic shaping.
class	ChannelTrafficShapingHandler	This implementation of the AbstractTrafficShapingHandler is for channel traffic shaping, that is to say a per channel limitation of the bandwidth.
class	GlobalChannelTrafficShapingHandler	This implementation of the AbstractTrafficShapingHandler is for global and per channel traffic shaping, that is to say a global limitation of the bandwidth, whatever the number of opened channels and a per channel limitation of the bandwidth. This version shall not be in the same pipeline than other TrafficShapingHandler. The general use should be as follow: Create your unique GlobalChannelTrafficShapingHandler like: GlobalChannelTrafficShapingHandler myHandler = new GlobalChannelTrafficShapingHandler(executor); The executor could be the underlying IO worker pool pipeline.addLast(myHandler); Note that this handler has a Pipeline Coverage of "all" which means only one such handler must be created and shared among all channels as the counter must be shared among all channels. Other arguments can be passed like write or read limitation (in bytes/s where 0 means no limitation) or the check interval (in millisecond) that represents the delay between two computations of the bandwidth and so the call back of the doAccounting method (0 means no accounting at all). Note that as this is a fusion of both Global and Channel Traffic Shaping, limits are in 2 sets, respectively Global and Channel. A value of 0 means no accounting for checkInterval.
class	GlobalTrafficShapingHandler	This implementation of the AbstractTrafficShapingHandler is for global traffic shaping, that is to say a global limitation of the bandwidth, whatever the number of opened channels.
