All Implemented Interfaces:

IThreadInfo, IVerboseToString

public class ThreadInfo
extends java.lang.Object
implements IThreadInfo

Information about a thread. Essentially captures the information that a ThreadReference contains, but this class allows the information to be stored so that the monitored VM can be resumed.
