    • estimateIndexedFunction

      public long estimateIndexedFunction(OFromClause target, OCommandContext context, OBinaryCompareOperator operator, Object right)

    • executeIndexedFunction

      public Iterable<OIdentifiable> executeIndexedFunction(OFromClause target, OCommandContext context, OBinaryCompareOperator operator, Object right)

    • canExecuteIndexedFunctionWithoutIndex

      public boolean canExecuteIndexedFunctionWithoutIndex(OFromClause target, OCommandContext context, OBinaryCompareOperator operator, Object right)
      tests if current expression is an indexed function AND that function can also be executed without using the index
      Parameters:
      target - the query target
      context - the execution context
      operator -
      right -
      Returns:
      true if current expression is an indexed function AND that function can also be executed without using the index, false otherwise

    • allowsIndexedFunctionExecutionOnTarget

      public boolean allowsIndexedFunctionExecutionOnTarget(OFromClause target, OCommandContext context, OBinaryCompareOperator operator, Object right)
      tests if current expression is an indexed function AND that function can be used on this target
      Parameters:
      target - the query target
      context - the execution context
      operator -
      right -
      Returns:
      true if current expression involves an indexed function AND that function can be used on this target, false otherwise

    • executeIndexedFunctionAfterIndexSearch

      public boolean executeIndexedFunctionAfterIndexSearch(OFromClause target, OCommandContext context, OBinaryCompareOperator operator, Object right)
      tests if current expression is an indexed function AND the function has also to be executed after the index search. In some cases, the index search is accurate, so this condition can be excluded from further evaluation. In other cases the result from the index is a superset of the expected result, so the function has to be executed anyway for further filtering
      Parameters:
      target - the query target
      context - the execution context
      Returns:
      true if current expression is an indexed function AND the function has also to be executed after the index search.
