Class LockableAspectInterceptor

java.lang.Object

org.alfresco.repo.lock.mem.LockableAspectInterceptor

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class LockableAspectInterceptor
extends java.lang.Object
implements org.aopalliance.intercept.MethodInterceptor

NodeService interceptor to spoof the cm:lockable aspect when reading a node that has an ephemeral lock on it. LockService policies such as beforeDeleteNode that protect locked nodes, would not fire for nodes with ephemeral locks on them unless they are reported to have the cm:lockable aspect on them. As ephemeral locks are only held in memory the nodes have not been marked with this aspect, so the aspect must be spoofed.

There is no need for this interceptor to worry about setProperty, removeProperty, setProperties, addProperties since if a service other than the lock service attempts to set cm:lockable properties when it is already locked, the beforeUpdateNode node service policy will disallow the update anyway.

Specified by:

invoke in interface org.aopalliance.intercept.MethodInterceptor

Throws:

java.lang.Throwable

enableForThread

public void enableForThread()

Enables the interceptor for the current thread. This would normally be used in a finally block to re-enable the interceptor for a previously disabled thread.

disableForThread

public void disableForThread()

Disables the interceptor for the current thread. Follow with a try/finally block as described for LockableAspectInterceptor.enableForThread().

setLockStore

public void setLockStore(LockStore lockStore)

setAuthenticationService

public void setAuthenticationService(AuthenticationService authenticationService)

setNodeService

public void setNodeService(org.alfresco.service.cmr.repository.NodeService nodeService)
