getEnforceStrength | public int getEnforceStrength()(Code) | | |
getMustExistRestriction | public MustExistRestriction getMustExistRestriction()(Code) | | |
mustExist | public boolean mustExist()(Code) | | Whether the Node of the value must exist
XXX MM: How can you have a non-existing node? I don't really get it. AFAIK all nodes exist.
especially since a node field is essentially a foreign key.
