Method Summary

Modifier and Type	Method	Description
boolean	canFindTargetsFor(EObject referenceContainer, EReference containingReference)	Determines if the decider is of any use for the given resolving procedure.
boolean	containsCandidates(EObject container, EReference containingReference)	Determines if the decider needs to look into the given reference.
EList<? extends EObject>	getAdditionalCandidates(String identifier, EObject container)	Allows for the decider to provide additional target candidates that are not directly contained in the traversed model tree.
boolean	isPossibleTarget(String id, EObject element)	Decides if the given element is a (possibly the final) target.
boolean	isSure()	Should return true, if the last time isPossibleTarget() returned true was the final decision (i.e., traversal can be stopped).
void	reset()	Resets the state of the decider before a complete new walk takes place.

canFindTargetsFor

public boolean canFindTargetsFor(EObject referenceContainer,
                                 EReference containingReference)

Description copied from interface: IResolutionTargetDecider

Determines if the decider is of any use for the given resolving procedure.

Returns:

decision

reset

public void reset()

Description copied from interface: IResolutionTargetDecider

Resets the state of the decider before a complete new walk takes place.

Specified by:

reset in interface IResolutionTargetDecider

Overrides:

reset in class AbstractDecider

getAdditionalCandidates

public EList<? extends EObject> getAdditionalCandidates(String identifier,
                                                        EObject container)

Description copied from interface: IResolutionTargetDecider

Allows for the decider to provide additional target candidates that are not directly contained in the traversed model tree. The additional candidates will be inserted into the scope behind the children of the given container.

Specified by:

getAdditionalCandidates in interface IResolutionTargetDecider

Overrides:

getAdditionalCandidates in class AbstractDecider

Returns:

null (corresponds to empty list) by default

isPossibleTarget

public boolean isPossibleTarget(String id,
                                EObject element)

Description copied from interface: IResolutionTargetDecider

Decides if the given element is a (possibly the final) target.

Returns:

decision

isSure

public boolean isSure()

Description copied from interface: IResolutionTargetDecider

Should return true, if the last time isPossibleTarget() returned true was the final decision (i.e., traversal can be stopped).

Specified by:

isSure in interface IResolutionTargetDecider

Overrides:

isSure in class AbstractDecider

Returns:

true by default

containsCandidates

public boolean containsCandidates(EObject container,
                                  EReference containingReference)

Description copied from interface: IResolutionTargetDecider

Determines if the decider needs to look into the given reference.

Returns:

decision
