Examples of org.apache.sling.api.resource.ResourceProvider.listChildren()

org.apache.sling.api.resource.ResourceProvider.listChildren()

Returns an Iterator of {@link Resource} objects loaded fromthe children of the given Resource. The returned {@link Resource} instancesare attached to the same {@link ResourceResolver} as the given parent resource.

This method may be called for resource providers whose root path list contains a path such that the resource path is a prefix of the list entry. This allows for the enumeration of deeply nested provided resources for which no actual parent hierarchy exists.

The returned iterator may in turn contain resources which do not actually exist but are required to traverse the resource tree. Such resources SHOULD be {@link SyntheticResource} objects whose resource type MUST be set to{@link #RESOURCE_TYPE_SYNTHETIC}. As with {@link #getResource(ResourceResolver,String)} the returned Resource objects mustnot be cached objects. @param parent The {@link Resource Resource} whose children are requested. @return An Iterator of {@link Resource} objects or null if the resourceprovider has no children for the given resource. @throws NullPointerException If parent is null. @throws SlingException If any error occurs acquiring the child resource iterator.
