public interface ISearchOperation
Represents 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 aNullPointerException
will be thrown during the calculation of the string.- Since:
- 2.0
