Class StackFrameStream

java.lang.Object

sun.jvm.hotspot.runtime.StackFrameStream

public class StackFrameStream
extends java.lang.Object

StackFrameStream iterates through the frames of a thread starting from top most frame. It automatically takes care of updating the location of all (callee-saved) registers. Notice: If a thread is stopped at a safepoint, all registers are saved, not only the callee-saved ones.

Use:

    for(StackFrameStream fst = new StackFrameStream(thread); !fst.isDone(); fst.next()) {
      ...
    }
