Example 1 with MethodFilter

use of cn.taketoday.util.ReflectionUtils.MethodFilter in project today-framework by TAKETODAY.

the class ReflectionUtilsTest method doWithMethodsUsingUserDeclaredMethodsComposedFilter.

@Test

    MethodFilter isSetterMethodOrNameContainsQ = m -> m.getName().startsWith("set") || m.getName().contains("q");
    MethodFilter methodFilter = ReflectionUtils.USER_DECLARED_METHODS.and(isSetterMethodOrNameContainsQ);
    ReflectionUtils.doWithMethods(TestObject.class, mc, methodFilter);
    assertThat(mc.getMethodNames()).containsExactlyInAnyOrder("setName", "setAge", "setSpouse", "absquatulate");
