public abstract class BaseCadenaAdapter
extends java.lang.Object
implements CadenaAdapter

Implementation base for Cadena adapters. Provides methods for iterating across all CadenaAdapter's adapting a particular model node, and collecting referrers who would be affected by a structural change.

Method Detail

addAffectedReferrers

public final void addAffectedReferrers(Notification notification,
                                       EObject notifyingObject,
                                       EStructuralFeature notifyingObjectFeature,
                                       java.util.Set<Triple<CadenaAdapter,EObject,EStructuralFeature>> referrers)

Description copied from interface: CadenaAdapter

Calculate the set of model objects whose well-formedness could be affected by a structural change to element.

In order to prevent infinite, circular call sequences, the protocol for adding a referrer should be as follows:

      Triple<CadenaAdapter, EObject, Integer> client = ...;
        
      if (!referrers.contains(client))
      {
          referrers.add(client);
         
          List<Adapter> adapters = client.second.eAdapters();
              
          for (Adapter a : adapters)
          {
              if (a instanceof CadenaAdapter)
              {
                  ((CadenaAdapter)a).addAffectedReferrers(
                      client.second,
                      a,
                      client.third);
              }
          }
      }
 

Specified by:

addAffectedReferrers in interface CadenaAdapter

checkNode

public void checkNode(EObject node)

Description copied from interface: CadenaAdapter

Called when a complete check of the model is performed. All checks that the adapter provides should be checked by this call.

Specified by:

checkNode in interface CadenaAdapter

Parameters:

node - The current node being checked.

notifyChanged

public void notifyChanged(Notification notification)

forwardReferenceChanged

public abstract void forwardReferenceChanged(Notification notification,
                                             EObject notifyingObject,
                                             EStructuralFeature notifyingObjectFeature)

Specified by:

forwardReferenceChanged in interface CadenaAdapter

setTarget

public void setTarget(Notifier newTarget)

getTarget

public Notifier getTarget()

isAdapterForType

public boolean isAdapterForType(java.lang.Object type)

getAffectedValues

public java.util.Set<? extends EObject> getAffectedValues(Notification notification)

addNotificationValues

public void addNotificationValues(Notification notification,
                                  java.util.Set<Pair<EObject,EStructuralFeature>> returnVal)

Adds a notification's old and new values (if they are instances of EObject) to an affected set.

setMarkers

public static void setMarkers(java.lang.Object markedObject,
                              java.lang.String markerType,
                              java.lang.String... messages)
