Method Detail

### findCacheInterceptor

    public static org.jboss.aop.advice.Interceptor findCacheInterceptor(org.jboss.aop.InstanceAdvisor advisor,
                                                                        org.jboss.cache.Fqn fqn)

  Find cache interceptor with exact fqn.

  Parameters:
    `advisor` -
    `fqn` -
  Returns:
    Interceptor

### findCacheInterceptor

    public static CacheFieldInterceptor findCacheInterceptor(org.jboss.aop.InstanceAdvisor advisor)

  Find existing cache interceptor. Since there is supposedly only one cache interceptor per pojo, this call should suffice. In addition, in cases of cross or circular reference, fqn can be different anyway.

  Parameters:
    `advisor` -
  Returns:
    Interceptor

### findCollectionInterceptor

    public static org.jboss.aop.advice.Interceptor findCollectionInterceptor(org.jboss.aop.InstanceAdvisor advisor)

  Find existing Collection interceptor. Since there is supposedly only one Collection interceptor per instance, this call should suffice. In addition, in cases of cross or circular reference, fqn can be different anyway.

  Parameters:
    `advisor` -
  Returns:
    Interceptor

### checkObjectType

    public static void checkObjectType(Object obj)

  Check whether the object type is valid. An object type is valid if it is either: aspectized, Serializable, or primitive type. Otherwise a runtime exception is thrown.

  Parameters:
    `obj` -

### constructFqn

    public static org.jboss.cache.Fqn constructFqn(org.jboss.cache.Fqn baseFqn,
                                                   Object relative)

### createInternalFqn

    public static org.jboss.cache.Fqn createInternalFqn(org.jboss.cache.Fqn fqn,
                                                        org.jboss.cache.Cache cache)

  Internal fqn is now structured as: a) If no region -- /__JBossInternal__/trueId/__ID__/xxxx b) If there is region -- /region/__JBossInternal__/xxx
