org.hawkular.inventory.base.RelationshipRules

public final class RelationshipRules
extends Object

Some well-known relationships have certain semantic rules that need to be checked for when creating/deleting them.

This class concentrates those checks so that they can be called easily from the various places in the codebase that work with relationships.
