Examples of org.apache.sling.api.adapter.Adaptable

org.apache.sling.api.adapter.Adaptable
The Adaptable interface identifies objects which can be adapted to other types or representations of the same object. For example a JCR Node based {@link org.apache.sling.api.resource.Resource} can adapt to theunderlying JCR Node or a file based resource could adapt to the underlying java.io.File.


  @Test
  public void testAdaptTo() throws ClassNotFoundException {
    log.info("testAdaptTo");


    Adaptable adaptable = SlingFunctions.getResource(resolver, TEST_PATH);
    Object adapted = SlingFunctions.adaptTo(adaptable,
        ValueMap.class.getCanonicalName());
    assertNotNull(adapted);
    assertTrue(adapted instanceof ValueMap);
