org.wso2.carbon.registry.core.Collection
The Collection Interface. Collection is specific type of resource that can contain other resources (including other collections). We call the resource contained in a collection as the children of the collection and the collection is called the parent of its children. The path of the child = The path of the parent + RegistryConstant.SEPERATOR + The resource name of the child. The ROOT collection is a specific instance of the Collection interface which doesn't have a parent.
