Method Detail

addObjectToPropertyWithKey

void addObjectToPropertyWithKey(java.lang.Object anObject,
                                java.lang.String aKey)

Adds the specified object to the relationship on this object specified by the key. For to-one relationships, this operation is the same as valueForKey.

removeObjectFromPropertyWithKey

void removeObjectFromPropertyWithKey(java.lang.Object anObject,
                                     java.lang.String aKey)

Removes the specified object from the relationship on this object specified by the key. For to-one relationships, this operation is the same as takeValueForKey with a null value.

addObjectToBothSidesOfRelationshipWithKey

void addObjectToBothSidesOfRelationshipWithKey(EORelationshipManipulation anObject,
                                               java.lang.String aKey)

As addObjectToProperty with key, but also performs the reciprocal operation on the other side of the relationship.

removeObjectFromBothSidesOfRelationshipWithKey

void removeObjectFromBothSidesOfRelationshipWithKey(EORelationshipManipulation anObject,
                                                    java.lang.String aKey)
