 Description  « Hide

The List/Map getter methods (e.g. getAttributeNodes()) on EntityGraph, AttributeNode, and Subgraph do not specify whether the List/Map returned is a mutable one or a copy. They should be specified as returning the exact collections so the collections can be mutated. If it is a copy then the ability to mutate an existing named entity graph using createEntityGraph(String) is quite limited. There would be no way to remove an attribute node or a subgraph, or for that matter even add a subgraph for an existing attribute node.

The alternative to returning the actual collections is to add methods to the API to enable the additional mutating operations.
