    • Field Detail

      • SEARCH_COST_REVERT

        static final int SEARCH_COST_REVERT
        Elementary search cost using a revert index.
        See Also:
        Constant Field Values

      • SEARCH_COST_REVERT_MULTIPLE

        static final int SEARCH_COST_REVERT_MULTIPLE
        Elementary search cost using multiple time the same revert index.
        See Also:
        Constant Field Values

      • ALL_PARTITION_MATCH_COST

        static final int ALL_PARTITION_MATCH_COST
        Elementary cost of return all rows of a partition.

        This is a very expensive operation since it matches all rows of a partition so it creates a large result and should always be performed after a regular scan.

        Constant Field Values

      • SEARCH_COST_SCAN_PRIMITIVE

        static final int SEARCH_COST_SCAN_PRIMITIVE
        Elementary search cost for full-scan of primitive data.
        See Also:
        Constant Field Values

      • SEARCH_COST_SCAN_OBJECT

        static final int SEARCH_COST_SCAN_OBJECT
        Elementary search cost for full-scan of object data.
        See Also:
        Constant Field Values

      • SEARCH_COST_SCAN_CONDITION

        static final int SEARCH_COST_SCAN_CONDITION
        Elementary search cost for full-scan of object data with a condition.
        See Also:
        Constant Field Values

      • SEARCH_COST_CHECK_CONDITION

        static final int SEARCH_COST_CHECK_CONDITION
        Elementary search cost for full-scan of object data.

        Constant Field Values

      • SEARCH_COST_SCAN_SWAPPED_PRIMITIVE

        static final int SEARCH_COST_SCAN_SWAPPED_PRIMITIVE
        Elementary search cost for full-scan of swapped object data.
        See Also:
        Constant Field Values

      • SEARCH_COST_SCAN_SWAPPED_OBJECT

        static final int SEARCH_COST_SCAN_SWAPPED_OBJECT
        Elementary search cost for full-scan of swapped object data.
        See Also:
        Constant Field Values

      • SEARCH_EFFICIENCY_DEFAULT

        static final int SEARCH_EFFICIENCY_DEFAULT
        Default search efficiency, also applied when efficiency cannot be predicted.
