Example 1 with ComponentMapper

use of com.artemis.ComponentMapper in project commons-gdx by gemserk.

the class GetComponentPerformanceTest method testTimeWithGetComponentFromMapper.

public long testTimeWithGetComponentFromMapper(int iterations) {
    World world = new World();
    Entity e = world.createEntity();
    e.addComponent(new MyTestComponent());
    e.refresh();
    ComponentMapper<MyTestComponent> myTestComponentMapper = new ComponentMapper<MyTestComponent>(MyTestComponent.class, world.getEntityManager());
    long startNanoTime = System.nanoTime();
    for (int i = 0; i < iterations; i++) {
        myTestComponentMapper.get(e);
    // MyTestComponent myTestComponent = myTestComponentMapper.get(e);
    }
    return System.nanoTime() - startNanoTime;
}
