Class DefaultThreadFactory

  • All Implemented Interfaces:
    java.util.concurrent.ThreadFactory, ThreadFactory
    Direct Known Subclasses:
    LazyThreadFactory
    public class DefaultThreadFactory
extends java.lang.Object
implements ThreadFactory
    Thread factory mainly responsible for naming of threads. Can be replaced by user. If use_numbering is set, a thread THREAD will be called THREAD-1, THREAD-2, and so on.

    If a pattern has been set (through setPattern()), then the cluster name and local address will also be added, e.g. THREAD-5,MyCluster,192.168.1.5:63754 or THREAD,MyCluster,192.168.1.5:63754

    If includeClusterName and includeLocalAddress are both false, and clusterName is set, then we assume we have a shared transport, and therefore print shared=clusterName.

                         java.lang.String cluster_name)
        Names a thread according to base_name, cluster name and local address. If includeClusterName and includeLocalAddress are null, but cluster_name is set, then we assume we have a shared transport and name the thread shared=clusterName. In the latter case, clusterName points to the singleton_name of TP.
        Parameters:
        base_name -
        thread -
        addr -
        cluster_name -
