    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.

    • 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

      Implements the interface specification. Do not override.
      Specified by:
      isActive in interface IResolutionTargetDecider
