Example 1 with FrameInstanceVisitor

use of com.oracle.truffle.api.frame.FrameInstanceVisitor in project graal by oracle.

the class StackTraceTest method testFrameAccess.

@Test
public void testFrameAccess() {
    CallTarget callTarget = createCallTarget(new TestCallWithCallTargetNode(null));
    CallTarget indirect = createCallTarget(new TestCallWithIndirectTargetNode(callTarget));
    CallTarget direct = createCallTarget(new TestCallWithDirectTargetNode(indirect));

        @Override
        Object execute(VirtualFrame frame) {
            Truffle.getRuntime().iterateFrames(new FrameInstanceVisitor<Object>() {

                    Assert.assertNull(frameInstance.getFrame(FrameAccess.NONE));
                    Frame readOnlyFrame = frameInstance.getFrame(FrameAccess.READ_ONLY);
                    FrameSlot slot = readOnlyFrame.getFrameDescriptor().findFrameSlot("demo");
                    Assert.assertEquals(42, readOnlyFrame.getValue(slot));
                    Frame readWriteFrame = frameInstance.getFrame(FrameAccess.READ_WRITE);
                    Assert.assertEquals(42, readWriteFrame.getValue(slot));
                    readWriteFrame.setObject(slot, 43);
                    Frame materializedFrame = frameInstance.getFrame(FrameAccess.MATERIALIZE);
                    Assert.assertEquals(43, materializedFrame.getValue(slot));
                    materializedFrame.setObject(slot, 44);
                    Assert.assertEquals(44, readOnlyFrame.getValue(slot));
                    Assert.assertEquals(44, readWriteFrame.getValue(slot));
                    return null;
