Class JavaStackWalker

java.lang.Object

com.oracle.svm.core.stack.JavaStackWalker

public final class JavaStackWalker
extends Object

Applies a StackFrameVisitor to each of the Java frames in a thread stack. It skips native frames, i.e., it only visits frames where Java frame information is available.

The stack walking code is allocation free (so that it can be used during garbage collection) and stateless (so that multiple threads can walk their stacks concurrently).
