Examples with Data com.oracle.truffle.api.test.polyglot.ValueHostInteropTest.Data used on opensource projects

Example 1 with Data

use of com.oracle.truffle.api.test.polyglot.ValueHostInteropTest.Data in project graal by oracle.

the class LanguageSPIHostInteropTest method invokeJavaLangObjectFields.

@Test
public void invokeJavaLangObjectFields() throws InteropException {
    Data data = new Data();
    TruffleObject obj = (TruffleObject) env.asGuestValue(data);
    Object string = ForeignAccess.sendInvoke(Message.createInvoke(0).createNode(), obj, "toString");
    assertTrue(string instanceof String && ((String) string).startsWith(Data.class.getName() + "@"));
    Object clazz = ForeignAccess.sendInvoke(Message.createInvoke(0).createNode(), obj, "getClass");
    assertTrue(clazz instanceof TruffleObject && env.asHostObject(clazz) == Data.class);
    assertEquals(true, ForeignAccess.sendInvoke(Message.createInvoke(1).createNode(), obj, "equals", obj));
    assertTrue(ForeignAccess.sendInvoke(Message.createInvoke(0).createNode(), obj, "hashCode") instanceof Integer);
    for (String m : new String[] { "notify", "notifyAll", "wait" }) {
        assertThrowsExceptionWithCause(() -> ForeignAccess.sendInvoke(Message.createInvoke(0).createNode(), obj, m), IllegalMonitorStateException.class);
    }
}

Example 2 with Data

use of com.oracle.truffle.api.test.polyglot.ValueHostInteropTest.Data in project graal by oracle.

the class LanguageSPIHostInteropTest method assertKeysAndProperties.

@SuppressWarnings("unchecked")
@Test
public void assertKeysAndProperties() {
    Data dataObj = new Data();
    TruffleObject data = (TruffleObject) env.asGuestValue(dataObj);
    TruffleObject keys = sendKeys(data);
    List<Object> list = context.asValue(keys).as(List.class);
    assertThat(list, CoreMatchers.hasItems("x", "y", "arr", "value", "map", "dataMap", "data", "plus"));
    Method[] objectMethods = Object.class.getMethods();
    for (Method objectMethod : objectMethods) {
        assertThat("No java.lang.Object methods", list, CoreMatchers.not(CoreMatchers.hasItem(objectMethod.getName())));
    }
    keys = sendKeys(data, true);
    list = context.asValue(keys).as(List.class);
    for (Method objectMethod : objectMethods) {
        assertThat("java.lang.Object methods", list, CoreMatchers.hasItem(objectMethod.getName()));
    }
}

Example 3 with Data

use of com.oracle.truffle.api.test.polyglot.ValueHostInteropTest.Data in project graal by oracle.

the class LanguageSPIHostInteropTest method testAsGuestValue.

@Test
public void testAsGuestValue() {
    Object object = new Object();
    // Test that asTruffleValue() returns the same as asTruffleObject() for non-primitive types:
    assertEquals(env.asGuestValue(object), env.asGuestValue(object));
    Data data = new Data();
    Object obj = env.asGuestValue(data);
    assertEquals(obj, env.asGuestValue(data));
    // Test that asTruffleValue() returns non-wraped primitives:
    object = 42;
    assertTrue(env.asGuestValue(object) == object);
    object = (byte) 42;
    assertTrue(env.asGuestValue(object) == object);
    object = (short) 42;
    assertTrue(env.asGuestValue(object) == object);
    object = 424242424242L;
    assertTrue(env.asGuestValue(object) == object);
    object = 42.42;
    assertTrue(env.asGuestValue(object) == object);
    object = true;
    assertTrue(env.asGuestValue(object) == object);
    object = "42";
    assertTrue(env.asGuestValue(object) == object);
    object = '4';
