All Implemented Interfaces:

IIteratingSearchOperation, ISearchOperation

public class IterateOverEDatatypeInstances
extends ExtendOperation<java.lang.Object>
implements IIteratingSearchOperation

Iterates over all EDataType instances using an VIATRA Base indexer. It is assumed that the indexer is initialized for the selected EDataType.

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.

Specified by:

onInitialize in interface ISearchOperation

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getVariablePositions

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

Specified by:

getVariablePositions in interface ISearchOperation

Returns:

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

getIteratedInputKey

public IInputKey getIteratedInputKey()

Description copied from interface: IIteratingSearchOperation

Get the IInputKey which instances this operation iterates upon.

Specified by:

getIteratedInputKey in interface IIteratingSearchOperation
