Class DelegatingSecurityContextCallable<V>

java.lang.Object

org.springframework.security.concurrent.DelegatingSecurityContextCallable<V>

All Implemented Interfaces:

java.util.concurrent.Callable<V>

public final class DelegatingSecurityContextCallable<V>
extends java.lang.Object
implements java.util.concurrent.Callable<V>

Wraps a delegate Callable with logic for setting up a SecurityContext before invoking the delegate Callable and then removing the SecurityContext after the delegate has completed.

If there is a SecurityContext that already exists, it will be restored after the call() method is invoked.
