getFeature
public org.eclipse.emf.ecore.EStructuralFeature getFeature()
-
createExecutor
public ISearchOperation.ISearchOperationExecutor createExecutor()
Description copied from interface:ISearchOperationInitializes a new operation executor for the given operation. Repeated calls must return different executor instances.- Specified by:
createExecutorin interfaceISearchOperation
-
toString
public java.lang.String toString()
- Overrides:
toStringin classjava.lang.Object
-
toString
public java.lang.String toString(java.util.function.Function<java.lang.Integer,java.lang.String> variableMapping)
Description copied from interface:ISearchOperationCreates 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 byISearchOperation.getVariablePositions(); otherwise aNullPointerExceptionwill be thrown during the calculation of the string.- Specified by:
toStringin interfaceISearchOperation
-
getVariablePositions
public java.util.List<java.lang.Integer> getVariablePositions()
- Specified by:
getVariablePositionsin interfaceISearchOperation- Returns:
- the ordered list of the variable numbers that are affected by the search operation
-
getIteratedInputKey
public IInputKey getIteratedInputKey()
Description copied from interface:IIteratingSearchOperationGet theIInputKeywhich instances this operation iterates upon.- Specified by:
