| /** |
| * Keys sets of elements by {@link OperationCallExp} elements and implements the {@link Iterable} interface. The {@link Iterable} |
| * view on this data structure iterates all values in this structure where duplicates are possible because each element of type |
| * <code>E</code> could occur for more than one {@link OperationCallExp}. |
| * <p> |
| * |
| * The <code>null</code> key is special and means that a result was computed without tracing back through an operation's |
| * <code>self</code> or parameter variable. For example, this is the case for an <code>allInstances()</code> call found inside an |
| * operation body. Such results always apply for the immediately-calling {@link OperationCallExp} and need to be added to their |
| * results. The special getter {@link #getCombinedResultsFor(OperationCallExp)} adds the values for key <code>null</code> to the |
| * values for the key specified. The <code>null</code> key can also be used to manage results not obtained within operation |
| * bodies at all. |
