  • Method Details

    • _p_getIdentity

      public IdentityIF _p_getIdentity()
      Description copied from interface: PersistentIF
      INTERNAL: Returns the identity of the object.
      Specified by:
      _p_getIdentity in interface PersistentIF

    • _p_getType

      public Class<?> _p_getType()
      Description copied from interface: PersistentIF
      INTERNAL: Returns the object.type. This information is used by the transaction to handle the persistent mapping for the object.
      Specified by:
      _p_getType in interface PersistentIF

    • _p_setIdentity

      public void _p_setIdentity(IdentityIF identity)
      Description copied from interface: PersistentIF
      INTERNAL: Sets the identity of the object.
      Specified by:
      _p_setIdentity in interface PersistentIF

    • _p_getTransaction

      public TransactionIF _p_getTransaction()
      Description copied from interface: PersistentIF
      INTERNAL: Returns the transaction that is responible for managing the object.
      Specified by:
      _p_getTransaction in interface PersistentIF

    • _p_setTransaction

      public void _p_setTransaction(TransactionIF txn)
      Description copied from interface: PersistentIF
      INTERNAL: Sets the transaction that is responible for managing the object.
      Specified by:
      _p_setTransaction in interface PersistentIF

    • syncAfterMerge

      public abstract void syncAfterMerge(IdentityIF source, IdentityIF target)

    • syncFieldsAfterMerge

      protected void syncFieldsAfterMerge(IdentityIF source, IdentityIF target, int... fields)

    • loadField

      protected <F> F loadField(int field)
      INTERNAL: Called when the instance requests the initialization of the specified field value. This call will lead to the value being retrieved from the data repository if the instance is managed by a transaction, otherwise a default value will be set.
      Returns:
      FIXME: only loaded values will be returned. if the default value is being set, the return value is null.

    • valueChanged

      protected void valueChanged(int field, Object value, boolean dchange)
