Class Inheritance

extends Object

java.lang.Object
sun.jvm.hotspot.runtime.StackFrameStream

Imports

sun.jvm.hotspot.utilities.*

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.

Note

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()) {
  ...
}
