Method Detail

getDataType

public org.eclipse.emf.ecore.EDataType getDataType()

onInitialize

public void onInitialize(MatchingFrame frame,
                         ISearchContext context)

Description copied from interface: ISearchOperation

During the execution of the corresponding plan, the onInitialize callback is evaluated before the execution of the operation may begin. Operations may use this method to initialize its internal data structures.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getVariablePositions

public java.util.List<java.lang.Integer> getVariablePositions()

Returns:

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