Examples with Layout com.oracle.truffle.api.object.Layout used on opensource projects

Example 1 with Layout

use of com.oracle.truffle.api.object.Layout in project graal by oracle.

the class ObjectTypeTest method objectTypeRespondsToIsArray.

@Test
public void objectTypeRespondsToIsArray() {
    final Layout layout = Layout.newLayout().build();
    final Shape rootShape = layout.createShape(OBJECT_TYPE);
    final DynamicObject obj = rootShape.newInstance();
    final boolean is = JavaInteropTest.isArray(obj);
    assertFalse("It is not array", is);
}

Example 2 with Layout

use of com.oracle.truffle.api.object.Layout in project graal by oracle.

the class ImplicitCastTest method testLocationDecoratorEquals.

@Test
public void testLocationDecoratorEquals() {
    Layout defaultLayout = new DefaultLayoutFactory().createLayout(Layout.newLayout());
    Shape defaultRootShape = defaultLayout.createShape(new ObjectType());
    Shape implicitCastRootShape = layout.createShape(new ObjectType());
    DynamicObject object1 = implicitCastRootShape.newInstance();
    object1.define("a", otherVal);
    Location location1 = object1.getShape().getProperty("a").getLocation();
    // Location of "a" should not change if an Integer is set
    object1.set("a", intVal);
    Assert.assertEquals(location1, object1.getShape().getProperty("a").getLocation());
    DynamicObject object2 = defaultRootShape.newInstance();
    object2.define("a", otherVal);
    Location location2 = object2.getShape().getProperty("a").getLocation();
    // This test relies on the assumption that both locations are of the same class
    Assert.assertEquals(location1.getClass(), location2.getClass());
    Assert.assertNotEquals(location1, location2);
