use of org.eclipse.elk.core.RecursiveGraphLayoutEngine in project elk by eclipse.

the class Issue680Test method test.

@Test
public void test() {
    Triple<ElkNode, ElkNode, ElkNode> nodes = testGraph();
    new RecursiveGraphLayoutEngine().layout(nodes.getFirst(), new NullElkProgressMonitor());

Example 12 with RecursiveGraphLayoutEngine

use of org.eclipse.elk.core.RecursiveGraphLayoutEngine in project elk by eclipse.

the class Issue682Test method test.

@Test
public void test() {
    Triple<ElkNode, ElkNode, ElkLabel> uut = testGraph();
    new RecursiveGraphLayoutEngine().layout(uut.getFirst(), new NullElkProgressMonitor());
    // Label position
    ElkLabel label = uut.getThird();
    assertThat(label.getX(), closeTo(54.0, EPSILON));
    assertThat(label.getY(), closeTo(21.0, EPSILON));
    // Node dimension
    assertThat(uut.getSecond().getWidth(), closeTo(label.getX() + label.getWidth() + 32, EPSILON));
// TODO the following line fails, it looks like the label's height is applied twice.
// assertThat(uut.getSecond().getHeight(), closeTo(label.getY() + label.getHeight() + 43, EPSILON));

Example 13 with RecursiveGraphLayoutEngine

use of org.eclipse.elk.core.RecursiveGraphLayoutEngine in project elk by eclipse.

the class ExperimentStatement method evaluate.

@Override

    createTestGraph();
    // Create a test controller if we have whitebox tests and the layout algorithm
    TestController testController = null;

        testController = new TestController(algorithm.getAlgorithmData().getId());
        testController.addLayoutExecutionListener(this);
    }
    // Let the recursive graph layout engine run the layout algorithm (if we have a test controller, that will
    // automatically cause white box tests to run)
    RecursiveGraphLayoutEngine layoutEngine = new RecursiveGraphLayoutEngine();
    layoutEngine.layout(testGraph, testController, new BasicProgressMonitor());
    // Stop listening to the test controller
    if (testController != null) {
        testController.removeLayoutExecutionListener(this);
    }
    // Run blackbox tests now that the layout algorithm has finished
    runBlackboxTests();
    // Cleanly handle all whitebox tests that did not execute because their processors didn't run
    simulateWhiteboxTestsForNotifiers();
