  • Method Details

    • clearDeferredChanges

      void clearDeferredChanges()
      INTERNAL: clear any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

    • hasDeferredChanges

      boolean hasDeferredChanges()
      INTERNAL: Return if the collection has any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

    • getAddedElements

      Collection<E> getAddedElements()
      INTERNAL: Return if the collection has any elements added that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

    • getRemovedElements

      Collection<E> getRemovedElements()
      INTERNAL: Return if the collection has any elements removed that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.

    • getDelegateObject

      C getDelegateObject()
      INTERNAL: Return the real collection object. This will force instantiation.

    • setUseLazyInstantiation

      void setUseLazyInstantiation(boolean useLazyInstantiation)
      INTERNAL Set whether this collection should attempt do deal with adds and removes without retrieving the collection from the dB
