Class GenericThread

java.lang.Object

com.ibm.dtfj.corereaders.GenericThread

public class GenericThread
extends Object

This class represents a single "generic" thread within the dump and is basically a data holding class (together with a toString() that allows a nice view of the class ..... - what attributes does a "generic thread" have as against extenders representing a specific type of thread (viz a J9 thread) J9Thread extends this Generic thread. System threads are generic threads and do not necessarily have same detail as java threads
