Example 1 with InvalidReplaceException

use of spoon.support.visitor.replace.InvalidReplaceException in project spoon by INRIA.

the class ReplaceTest method testReplaceExecutableReferenceByAnotherOne.

@Test
public void testReplaceExecutableReferenceByAnotherOne() throws Exception {
    // contract: replace an executable reference to another one in an invocation.
    final Factory factory = build(Tacos.class);
    final CtType<Tacos> aTacos = factory.Type().get(Tacos.class);
    final CtInvocation inv = aTacos.getMethodsByName("m3").get(0).getElements(new TypeFilter<>(CtInvocation.class)).get(0);
    final CtExecutableReference oldExecutable = inv.getExecutable();
    final CtExecutableReference<Object> newExecutable = factory.Executable().createReference("void java.io.PrintStream#print(java.lang.String)");
    assertSame(oldExecutable, inv.getExecutable());
    oldExecutable.replace(newExecutable);
    assertSame(newExecutable, inv.getExecutable());
    assertEquals("print(java.lang.String)", inv.getExecutable().toString());
    assertEquals("java.io.PrintStream", inv.getExecutable().getDeclaringType().toString());
    // contract: replace of single value by multiple values in single value field must fail
    try {
        newExecutable.replace(Arrays.asList(oldExecutable, null));
        fail();
    } catch (InvalidReplaceException e) {
    // OK
    }
}
