    • setInternalID

      void setInternalID(long id, ValueStoreRevision revision)
      Sets the ID that is used for this value in a specific revision of the value store.

    • getInternalID

      long getInternalID()
      Gets the ID that is used in the lmdb store for this Value.
      Returns:
      The value's ID, or UNKNOWN_ID if not yet set.

    • init

      void init()
      Initializes this value if it was a lazy value (ID-only value) before.

    • getValueStoreRevision

      ValueStoreRevision getValueStoreRevision()
      Gets the revision of the value store that created this value. The value's internal ID is only valid when it's value store revision is equal to the value store's current revision.
      Returns:
      The revision of the value store that created this value at the time it last set the value's internal ID.

    • setFromInitializedValue

      @InternalUseOnly void setFromInitializedValue(LmdbValue initializedValue)
      Sets this value's data from an initialized value.

      This must be only called within a synchronized block in the init() method of the uninitialized value.

      Parameters:
      initializedValue - the initialized value to copy data from
