Interface JPAEdmAssociationView

All Superinterfaces:
JPAEdmBaseView
public interface JPAEdmAssociationView extends JPAEdmBaseView

A View on Java Persistence Entity Relationship and Entity Data Model Association.

The implementation of the view provides access to EDM Association created from Java Persistence Entity Relationships. The implementation acts as a container for list of association that are consistent. An Association is said to be consistent only

  1. If both the Ends of Association are consistent
  2. If referential constraint exists for the Association then it should be consistent

      void addJPAEdmAssociationView(JPAEdmAssociationView associationView, JPAEdmAssociationEndView associationEndView)
      The method adds JPAEdmAssociationView to its container
      Parameters:
      associationView - of type JPAEdmAssociationView
      associationEndView - JPAEdmAssociationEndView

    • searchAssociation

      Association searchAssociation(JPAEdmAssociationEndView view)
      The method searches for an Association in its container against the search parameter view of type JPAEdmAssociationView . The Association in the container view is searched against the consistent list of Association stored in this container.

      view - of type JPAEdmAssociationView
      Returns:
      Association if found in the container

    • addJPAEdmRefConstraintView

      void addJPAEdmRefConstraintView(JPAEdmReferentialConstraintView refView)
      The method adds the referential constraint view to its container.

      Note: The referential constraint view is added only if it exists.

      Parameters:
      refView - of type JPAEdmReferentialConstraintView

    • getJPAEdmReferentialConstraintView

      JPAEdmReferentialConstraintView getJPAEdmReferentialConstraintView()
      The method returns the referential constraint view that is currently being processed.
      Returns:
      an instance of type JPAEdmReferentialConstraintView

    • getNumberOfAssociationsWithSimilarEndPoints

      int getNumberOfAssociationsWithSimilarEndPoints(JPAEdmAssociationEndView view)
      The method searches for the number of associations with similar endpoints in its container against the search parameter view of type JPAEdmAssociationView . The Association in the container view is searched against the consistent list of Association stored in this container.
      Parameters:
      view - of type JPAEdmAssociationView
      Returns:
      Association if found in the container
