visitFrame

public final boolean visitFrame(org.graalvm.word.Pointer sp,
                                org.graalvm.nativeimage.c.function.CodePointer ip,
                                CodeInfo codeInfo,
                                DeoptimizedFrame deoptimizedFrame)

Description copied from class: StackFrameVisitor

Called for each frame that is visited. Note that unless this method is annotated with Uninterruptible or executing within a safepoint, the frame on the stack could be deoptimized at any safepoint check. Nevertheless, the passed codeInfo remains valid for accessing information about the code at the (possibly outdated) instruction pointer (this is ensured by the caller).

Specified by:

visitFrame in class StackFrameVisitor

Parameters:

sp - The stack pointer of the frame being visited.

ip - The instruction pointer of the frame being visited.

codeInfo - Information on the code at the IP, for use with CodeInfoAccess.

deoptimizedFrame - The information about a deoptimized frame, or null if the frame is not deoptimized.

Returns:

true if visiting should continue, false otherwise.
