Package org.apache.olingo.odata2.jpa.processor.api.access

Class JPAMethodContext

java.lang.Object

org.apache.olingo.odata2.jpa.processor.api.access.JPAMethodContext

All Implemented Interfaces:

JPAMethodContextView

public abstract class JPAMethodContext
extends Object
implements JPAMethodContextView

The abstract class is a compilation of objects required for building specific instances of JPA Method Context. Extend this class to implement specific implementations of JPQL context types (Create,Update,Function). A JPA method Context is constructed from an OData request. Depending on OData CUD/FunctionImport operation performed on an Entity, a corresponding JPA method context object is built. The object thus built can be used for executing operations on JPA Entity/Custom processor objects.
A default implementation is provided by the library.
