Method Details

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(Function<Integer,String> variableMapping)

Description copied from interface: ISearchOperation

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 by ISearchOperation.getVariablePositions(); otherwise a NullPointerException will be thrown during the calculation of the string.

Specified by:

toString in interface ISearchOperation

createExecutor

public ISearchOperation.ISearchOperationExecutor createExecutor()

Description copied from interface: ISearchOperation

Initializes a new operation executor for the given operation. Repeated calls must return different executor instances.

Specified by:

createExecutor in interface ISearchOperation

getVariablePositions

public List<Integer> getVariablePositions()

Specified by:

getVariablePositions in interface ISearchOperation

Returns:

the ordered list of the variable numbers that are affected by the search operation
