Examples with Filter org.edx.mobile.model.Filter used on opensource projects

Example 1 with Filter

use of org.edx.mobile.model.Filter in project edx-app-android by edx.

the class CourseComponentTest method testFindWithFilter.

@Test
public void testFindWithFilter() throws Exception {
    CourseComponent found = course.find(new Filter<CourseComponent>() {

        @Override
        public boolean apply(CourseComponent component) {
            return false;
        }
    });
    assertTrue("find with filter failed", found == null);
    found = course.find(new Filter<CourseComponent>() {

        @Override
        public boolean apply(CourseComponent component) {
            return component == unit1;
        }
    });
    assertTrue("find with filter failed", found == unit1);
    found = course.find(new Filter<CourseComponent>() {

        @Override
        public boolean apply(CourseComponent component) {
            return component.getType() == BlockType.VIDEO;
