Example 10 with CtBinaryOperator

use of spoon.reflect.code.CtBinaryOperator in project spoon by INRIA.

the class TypeTest method testTypeAccessOnPrimitive.

@Test
public void testTypeAccessOnPrimitive() throws Exception {
    Factory factory = createFactory();
    CtClass<?> clazz = // 
    factory.Code().createCodeSnippetStatement(// 
    "class X {" + // 
    "public void foo() {" + // 
    " Class klass=null;" + // 
    "  boolean x= (klass == short.class);" + "}};").compile();
    CtMethod<?> foo = (CtMethod<?>) clazz.getMethods().toArray()[0];
    CtBlock<?> body = foo.getBody();
    CtLocalVariable<?> ass = body.getStatement(1);
    CtBinaryOperator<?> op = (CtBinaryOperator<?>) ass.getDefaultExpression();
    assertEquals("Class", op.getLeftHandOperand().getType().getSimpleName());
    assertFalse(op.getLeftHandOperand().getType().isPrimitive());
    assertEquals("Class", op.getRightHandOperand().getType().getSimpleName());
    assertTrue(op.getRightHandOperand() instanceof CtFieldRead);
    assertFalse(op.getRightHandOperand().getType().isPrimitive());
