All Implemented Interfaces:
Serializable, Comparable<ValidationCondition>
public enum ValidationCondition extends Enum<ValidationCondition>
Defines conditions for which validators can be assigned to. These conditions describe a situation where special request handling might be necessary. In these cases we do not override the actual request handling code, but based on certain request properties we might reject a request early, or we might modify the request, or the response received/sent from/to the client.
