public interface ISearchOperationRepresents a search operation executable by the LS engine. It is expected that an operation can be shared among multiple LS matchers, but the created executors are not.

Method Detail
-
createExecutor
ISearchOperation.ISearchOperationExecutor createExecutor()
Initializes a new operation executor for the given operation. Repeated calls must return different executor instances.- Since:
- 2.0
-
getVariablePositions
java.util.List<java.lang.Integer> getVariablePositions()
- Returns:
- the ordered list of the variable numbers that are affected by the search operation
-
toString
java.lang.String toString(java.util.function.Function<java.lang.Integer,java.lang.String> variableMapping)
Creates a string representation of the search operation by replacing the variable numbers according to the parameter function. It is expected that the provided function does return a non-null value for each variable index that is returned bygetVariablePositions(); otherwise aNullPointerExceptionwill be thrown during the calculation of the string.- Since:
- 2.0
