Class StepFilter

Implemented Interfaces:
IEventFilter
public class StepFilter
extends Object
implements IEventFilter
"An event filter which restricts reported step events to those which satisfy depth and size constraints. This modifier can only be used with step event kinds." This "filter" is not really a filter. It is simply a way to communicate stepping information in a convenient way between the JDWP backend and the virtual machine. Consequently, this "filter" always matches.

Constructor Summary

StepFilter(ThreadId tid, int size, int depth)
Constructs a new StepFilter

Method Summary

int
getDepth()
Returns the relative call stack limit (into, over, out)
int
getSize()
Returns the size of each step (insn, line)
ThreadId
getThread()
Returns the thread in which to step
boolean
matches(Event event)
Does the given event match the filter?
