public class ChildrenAsPropertyResource
extends org.apache.sling.api.resource.ResourceWrapper

Class to wrapper a real resource to facilitate the persistence of children resources in a property (serialized as JSON). Can be used as follows... To write data: Resource real = resolve.getResource("/content/real"); ChildrenAsPropertyResource wrapper = new ChildrenAsPropertyResource(real); Resource child = wrapper.create("child-1", "nt:unstructured"); ModifiableValueMap mvm = child.adaptTo(ModifiableValueMap.class); mvm.put("prop-1", "some data"); mvm.put("prop-2", Calendar.getInstance()); wrapper.persist(); resolver.commit(); To read data: Resource real = resolve.getResource("/content/real"); ChildrenAsPropertyResource wrapper = new ChildrenAsPropertyResource(real); for(Resource child : wrapper.getChildren()) { child.getValueMap().get("prop-1", String.class); }
