Examples of com.sun.jdi.StackFrame.location()

com.sun.jdi.StackFrame.location()
Returns the {@link Location} of the current instruction in the frame.The method for which this frame was created can also be accessed through the returned location. For the top frame in the stack, this location identifies the next instruction to be executed. For all other frames, this location identifies the instruction that caused the next frame's method to be invoked. If the frame represents a native method invocation, the returned location indicates the class and method, but the code index will not be valid (-1). @return the {@link Location} of the current instruction. @throws InvalidStackFrameException if this stack frame has becomeinvalid. Once the frame's thread is resumed, the stack frame is no longer valid.
