java.lang.Object
  org.nuxeo.ecm.core.api.ejb.ReentrantCallsShieldInterceptor

public class ReentrantCallsShieldInterceptor
extends java.lang.Object

This interceptor is used to detect reentrant calls to DocumentManagerBean. In case of reentrancy it store the local CoreSession instance in a thread local that is must be used by all the code using CoreSession withing the scope of the current call. Typically, AbstractSession, EventHandlers and DocumentModelImpl may use the CoreSession while current thread is processing a call to DocumentManagerBean. Thanks to the threadlocal Local Session, the call can be nested without raising the ConcurrentAccessException
