      public BitSet(DNStateManager sm, AbstractMemberMetaData mmd)
      Creates a BitSet object. Assigns owning object and field name.
      Parameters:
      sm - StateManager for the owning object
      mmd - Metadata for the member

  • Method Details

    • initialise

      public void initialise()
      Description copied from interface: SCO
      Method to initialise the SCO for use, and allowing the SCO to be loaded from the datastore (when we have a backing store). This can be utilised to perform any eager loading of information from the datastore.
      Specified by:
      initialise in interface SCO<BitSet>

    • initialise

      public void initialise(BitSet newValue, Object oldValue)
      Description copied from interface: SCO
      Method to initialise the SCO for use, where replacing an old value with a new value such as when calling a setter field passing in a new value. Note that oldValue is marked as Object since for cases where the member type is Collection the newValue could be, for example, ArrayList, and the oldValue of type Collection (representing null).
      Specified by:
      initialise in interface SCO<BitSet>
      Parameters:
      newValue - New value (to wrap)
      oldValue - Old value (to use in deciding what needs deleting etc)

    • initialise

      public void initialise(BitSet set)
      Description copied from interface: SCO
      Method to initialise the SCO for use with the provided initial value. This is used, for example, when retrieving the field from the datastore and setting it in the persistable object.
      Specified by:
      initialise in interface SCO<BitSet>
      Parameters:
      set - the object from which to copy the value.

    • getValue

      public BitSet getValue()
      Accessor for the unwrapped value that we are wrapping.
      Specified by:
      getValue in interface SCO<BitSet>
      Returns:
      The unwrapped value

    • unsetOwner

      public void unsetOwner()
      Utility to unset the owner.
      Specified by:
      unsetOwner in interface SCO<BitSet>

    • getOwner

      public Object getOwner()
      Accessor for the owner.
      Specified by:
      getOwner in interface SCO<BitSet>
      Returns:
      The owner

    • getFieldName

      public String getFieldName()
      Accessor for the field name
      Specified by:
      getFieldName in interface SCO<BitSet>
      Returns:
      The field name

    • makeDirty

      public void makeDirty()
      Utility to mark the object as dirty

    • detachCopy

      public BitSet detachCopy(FetchPlanState state)
      Method to detach a copy.
      Specified by:
      detachCopy in interface SCO<BitSet>
      Parameters:
      state - State for detachment process
      Returns:
      A copy of the object

    • attachCopy

      public void attachCopy(BitSet value)
      Method to attached the passed value.
      Specified by:
      attachCopy in interface SCO<BitSet>
      Parameters:
      value - The new value

    • clone

      public Object clone()
      Creates and returns a copy of this object.

      Mutable second-class Objects are required to provide a public clone method in order to allow for copying persistable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException.

      Specified by:
      clone in interface SCO<BitSet>
      Overrides:
      clone in class BitSet
      Returns:
      A clone of the object

    • writeReplace

      protected Object writeReplace() throws ObjectStreamException
      The writeReplace method is called when ObjectOutputStream is preparing to write the object to the stream. The ObjectOutputStream checks whether the class defines the writeReplace method. If the method is defined, the writeReplace method is called to allow the object to designate its replacement in the stream. The object returned should be either of the same type as the object passed in or an object that when read and resolved will result in an object of a type that is compatible with all references to the object.
      Returns:
      the replaced object
      Throws:
      ObjectStreamException - if an error occurs
