Method Summary

Modifier and Type	Method	Description
void	activate()	Implements the interface specification.
boolean	continueAfterReference()	Defines, if the scoping for this decider allows to look behind the point where the reference, for which the target is searched, was defined.
void	deactivate()	Implements the interface specification.
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	isActive()	Implements the interface specification.
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.
boolean	walkInto(EObject element)	Determines if references given element, which is a child of the elements visited by default in the tree traversing, should also be considered.

public AbstractDecider()

Method Detail

continueAfterReference

public boolean continueAfterReference()

Description copied from interface: IResolutionTargetDecider

Defines, if the scoping for this decider allows to look behind the point where the reference, for which the target is searched, was defined.

Specified by:

continueAfterReference in interface IResolutionTargetDecider

Returns:

true by default

walkInto

public boolean walkInto(EObject element)

Description copied from interface: IResolutionTargetDecider

Determines if references given element, which is a child of the elements visited by default in the tree traversing, should also be considered.

Specified by:

walkInto in interface IResolutionTargetDecider

Parameters:

element -

Returns:

false by default

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

Parameters:

identifier -

container -

Returns:

null (corresponds to empty list) by default

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

Returns:

true by default

activate

public void activate()

Implements the interface specification. Do not override.

Specified by:

activate in interface IResolutionTargetDecider

deactivate

public void deactivate()

Implements the interface specification. Do not override.

Specified by:

deactivate in interface IResolutionTargetDecider

isActive

public boolean isActive()

Implements the interface specification. Do not override.

Specified by:

isActive in interface IResolutionTargetDecider

Returns:

true if the decider is active. false otherwise.

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
