    • allQueries

      Class allQueries
      This AllQueries Query Redirector will be applied to any executing object query that does not have a more precise redirector (like the ReadObjectQuery Redirector) or a redirector set directly on the query. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing.
      Default:
      void.class

    • readAll

      Class readAll
      A Default ReadAll Query Redirector will be applied to any executing ReadAllQuery that does not have a redirector set directly on the query. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing. For users executing a JPA Query through the getResultList() API this is the redirector that will be invoked
      Default:
      void.class

    • readObject

      Class readObject
      A Default ReadObject Query Redirector will be applied to any executing ReadObjectQuery that does not have a redirector set directly on the query. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing. For users executing a JPA Query through the getSingleResult() API or EntityManager.find() this is the redirector that will be invoked
      Default:
      void.class

    • report

      Class report
      A Default ReportQuery Redirector will be applied to any executing ReportQuery that does not have a redirector set directly on the query. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing. For users executing a JPA Query that contains agregate functions or selects multiple entities this is the redirector that will be invoked
      Default:
      void.class

    • update

      Class update
      A Default Update Query Redirector will be applied to any executing UpdateObjectQuery or UpdateAllQuery that does not have a redirector set directly on the query. In EclipseLink an UpdateObjectQuery is executed whenever flushing changes to the datasource. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing.
      Default:
      void.class

    • insert

      Class insert
      A Default Insert Query Redirector will be applied to any executing InsertObjectQuery that does not have a redirector set directly on the query. In EclipseLink an InsertObjectQuery is executed when persisting an object to the datasource. Query redirectors allow the user to intercept query execution preventing it or alternately performing some side effect like auditing.
      Default:
      void.class

    • delete

      Class delete
      A Default Delete Object Query Redirector will be applied to any executing DeleteObjectQuery or DeleteAllQuery that does not have a redirector set directly on the query.
