Examples with EventRequest com.sun.jdi.request.EventRequest used on opensource projects

Example 1 with EventRequest

use of com.sun.jdi.request.EventRequest in project che by eclipse.

the class JavaDebugger method addBreakpoint.

@Override
public void addBreakpoint(Breakpoint breakpoint) throws DebuggerException {
    final String className = findFQN(breakpoint);
    final int lineNumber = breakpoint.getLocation().getLineNumber();
    List<ReferenceType> classes = vm.classesByName(className);
    // it may mean that class doesn't loaded by a target JVM yet
    if (classes.isEmpty()) {
        deferBreakpoint(breakpoint);
        throw new DebuggerException("Class not loaded");
    }
    ReferenceType clazz = classes.get(0);
    List<com.sun.jdi.Location> locations;
    try {
        locations = clazz.locationsOfLine(lineNumber);
    } catch (AbsentInformationException | ClassNotPreparedException e) {
        throw new DebuggerException(e.getMessage(), e);
    }
    if (locations.isEmpty()) {
        throw new DebuggerException("Line " + lineNumber + " not found in class " + className);
    }
    com.sun.jdi.Location location = locations.get(0);
    if (location.method() == null) {
        // Line is out of method.
        throw new DebuggerException("Invalid line " + lineNumber + " in class " + className);
    }
    // Ignore new breakpoint if already have breakpoint at the same location.
    EventRequestManager requestManager = getEventManager();
    for (BreakpointRequest breakpointRequest : requestManager.breakpointRequests()) {
        if (location.equals(breakpointRequest.location())) {
            LOG.debug("Breakpoint at {} already set", location);
            return;
        }
    }
    try {
        EventRequest breakPointRequest = requestManager.createBreakpointRequest(location);
        breakPointRequest.setSuspendPolicy(EventRequest.SUSPEND_ALL);
        String expression = breakpoint.getCondition();
        if (!(expression == null || expression.isEmpty())) {
            ExpressionParser parser = ExpressionParser.newInstance(expression);
            breakPointRequest.putProperty("org.eclipse.che.ide.java.debug.condition.expression.parser", parser);
        }
        breakPointRequest.setEnabled(true);
    } catch (NativeMethodException | IllegalThreadStateException | InvalidRequestStateException e) {
        throw new DebuggerException(e.getMessage(), e);
    }
    debuggerCallback.onEvent(new BreakpointActivatedEventImpl(new BreakpointImpl(breakpoint.getLocation(), true, breakpoint.getCondition())));
    LOG.debug("Add breakpoint: {}", location);
}

        eventRequestSpecs.add(spec);
        EventRequest eventRequest = spec.resolveEagerly();
