Class TransferQueueBundler

  • All Implemented Interfaces:
    java.lang.Runnable, Bundler
    Direct Known Subclasses:
    AlternatingBundler, SimplifiedTransferQueueBundler

    public class TransferQueueBundler
    extends BaseBundler
    implements java.lang.Runnable
    This bundler adds all (unicast or multicast) messages to a queue until max size has been exceeded, but does send messages immediately when no other messages are available. https://issues.jboss.org/browse/JGRP-1540

      • getStats

        public java.util.Map<java.lang.String,​java.lang.Object> getStats()
        Description copied from interface: Bundler
        Returns stats about the bundler itself.
        Specified by:
        getStats in interface Bundler
        Returns:
        Stats, may be null
      • resetStats

        public void resetStats()
        Specified by:
        resetStats in interface Bundler
      • init

        public void init​(TP tp)
        Description copied from interface: Bundler
        Called after creation of the bundler
        Specified by:
        init in interface Bundler
        Overrides:
        init in class BaseBundler
        Parameters:
        tp - the transport, for further reference
      • size

        public int size()
        Description copied from class: BaseBundler
        Returns the total number of messages in the hashmap
        Specified by:
        size in interface Bundler
        Overrides:
        size in class BaseBundler
      • getQueueSize

        public int getQueueSize()
        Description copied from interface: Bundler
        If the bundler has a queue and it should be managed by a queuing discipline (like Random Early Detection), then return the number of elements in the queue, else -1. In the latter case, the queue won't be managed.
        This method needs to be fast as it might get called on every message to be sent.
        Specified by:
        getQueueSize in interface Bundler
