public boolean onMethodReturn(MethodRef method, Object returnValue) {
    boolean active = false;
    for (MethodHook hook : method.getMethodHooks()) {
        if (hook.onMethodExit(method, returnValue)) {
            // OK, tell the Debug API to suspend the thread now
            debuggerController.prepareMethodBreakpoint(new MethodBreakpointEvent((MethodBreakpointInfo) hook, returnValue));
            debuggerController.suspend(context.asGuestThread(Thread.currentThread()));

            }
        }
    }
    return active;

Example 2 with MethodBreakpointEvent

use of com.oracle.truffle.espresso.jdwp.impl.MethodBreakpointEvent in project graal by oracle.

the class VMEventListenerImpl method onMethodEntry.

@Override
@TruffleBoundary
public boolean onMethodEntry(MethodRef method, Object scope) {
    boolean active = false;
    // collect variable information from scope
    List<MethodVariable> variables = new ArrayList<>(1);

                    Object value = UNCACHED.readMember(scope, identifier);
                    variables.add(new MethodVariable(identifier, value));
                }
            }
        }
    } catch (UnsupportedMessageException | InvalidArrayIndexException | UnknownIdentifierException e) {
    // not able to fetch locals, so leave variables list empty
    }
    for (MethodHook hook : method.getMethodHooks()) {

        if (hook.onMethodEnter(method, variables.toArray(new MethodVariable[variables.size()]))) {
            // OK, tell the Debug API to suspend the thread now
            debuggerController.prepareMethodBreakpoint(new MethodBreakpointEvent((MethodBreakpointInfo) hook, null));
