Examples of org.eclipse.persistence.mappings.querykeys.QueryKey

org.eclipse.persistence.mappings.querykeys.QueryKey
Purpose: Define a Java appropriate alias to a database field or function.
Responsibilities:
- Define the name of the alias.
- Define the descriptor of the alias.

        // No mapping is defined for the single path, check for a query key
        else {

          if (queryKey != null) {
            // Make sure we keep track of its type
            if (type != null) {
              type[0] = queryContext.calculateQueryKeyType(queryKey);
            }


            // This will tell us how to create the Expression
            collectionMapping = queryKey.isCollectionQueryKey();


            // Retrieve the reference descriptor so we can continue traversing the path
            if (!last && queryKey.isForeignReferenceQueryKey()) {
              ForeignReferenceQueryKey referenceQueryKey = (ForeignReferenceQueryKey) queryKey;
              descriptor = queryContext.getDescriptor(referenceQueryKey.getReferenceClass());
