DETAIL: FIELD | CONSTR | METHOD

org.jboss.ejb.plugins
Class EntityMultiInstanceInterceptor

java.lang.Object
  org.jboss.ejb.plugins.AbstractInterceptor
      org.jboss.ejb.plugins.EntityMultiInstanceInterceptor

All Implemented Interfaces:: AllowedOperationsFlags, ContainerPlugin, Interceptor, org.jboss.system.Service

Deprecated. this interceptor was used with Instance Per Transaction containers which do not use a global cache but cache instances per transaction and always passivate instances at commit time (commit option C). This interceptor used org.jboss.ejb.TxEntityMap to compensate the absence of a real per transaction cache implementation. Now, the differences between IPT and standard container are:

org.jboss.ejb.plugins.PerTxEntityInstanceCache as the cache implementation;

NoLock as the locking policy;

empty container-cache-conf element.

(alex@jboss.org) The instance interceptors role is to acquire a context representing the target object from the cache.
