      • matchingValues

        @Deprecated
        public boolean matchingValues​(Comparison comparison,
                                      Object object1,
                                      Object object2)
        Deprecated.
        Check that the two given values are "equal", considering the specifics of EMF.
        Parameters:
        comparison - Provides us with the Match necessary for EObject comparison.
        object1 - First of the two objects to compare here.
        object2 - Second of the two objects to compare here.
        Returns:
        true if both objects are to be considered equal, false otherwise.

      • matchingEObjects

        protected boolean matchingEObjects​(EObject object1,
                                           EObject object2)
        Compares two values as EObjects, using their Match if it can be found, comparing through their URIs otherwise.
        Parameters:
        object1 - First of the two objects to compare here.
        object2 - Second of the two objects to compare here.
        Returns:
        true if these two EObjects are to be considered equal, false otherwise.
      • getMatch

        protected Match getMatch​(EObject o)
        Returns the match of this EObject if any, null otherwise.
        Parameters:
        o - The object for which we need the associated Match.
        Returns:
        Match of this EObject if any, null otherwise.
      • matchingURIs

        protected boolean matchingURIs​(EObject object1,
                                       EObject object2)
        Compare the URIs (of similar concept) of EObjects.
        Parameters:
        object1 - First of the two objects to compare here.
        object2 - Second of the two objects to compare here.
        Returns:
        true if these two EObjects have the same URIs, false otherwise.
      • getURI

        @Deprecated
        public URI getURI​(EObject object)
        Deprecated.
        The EqualityHelper often needs to get an EObject uri. As such it has an internal cache that clients might leverage through this method.
        Parameters:
        object - any EObject.
        Returns:
        the URI of the given EObject, or null if we somehow could not compute it.
      • getCache

        @Deprecated
        public com.google.common.cache.Cache<EObject,​URI> getCache()
        Deprecated.
        Returns the cache used by this object.
        Returns:
        the cache used by this object.
      • createDefaultCache

        public static com.google.common.cache.LoadingCache<EObject,​URI> createDefaultCache​(com.google.common.cache.CacheBuilder<Object,​Object> cacheBuilder)
        Create a cache as required by EqualityHelper.
        Parameters:
        cacheBuilder - The builder to use to instantiate the cache.
        Returns:
        the new cache.
