public interface HandleAware
Interface for objects that can be identified by a handle. This interface provides most of the functionality required for making a bean identifiable, other than allocating the handle itself.

Objects that are HandleAware can be added to other HandleAware objects as children to form a graph, or path, to the object which uniquely identifies the object, and forms a key that is used for persistence or identifying an instance symbolically to an endpoint. The user is responsible for connecting HandleAware objects into a meaningful graph for the application.

The handle, while a structured string, is considered opaque and should not be manufactured, parsed, or trimmed.

    • addHandleChild

      default void addHandleChild(String prefix, HandleAware child)
      Adds a child HandleAware bean to this bean. This causes the child to have a path through this bean using the specified prefix. This bean does not maintain a reference to the child, and is only used for logical path construction of handles.
