org.acegisecurity
Interface AfterInvocationManager

public interface AfterInvocationManager

Reviews the Object returned from a secure object invocation, being able to modify the Object or throw an AccessDeniedException.

Typically used to ensure the principal is permitted to access the domain object instance returned by a service layer bean. Can also be used to mutate the domain object instance so the principal is only able to access authorised bean properties or Collection elements. Often used in conjunction with an org.acegisecurity.acl.AclManager to obtain the access control list applicable for the domain object instance.

Special consideration should be given to using an AfterInvocationManager on bean methods that modify a database. Typically an AfterInvocationManager is used with read-only methods, such as public DomainObject getById(id). If used with methods that modify a database, a transaction manager should be used to ensure any AccessDeniedException will cause a rollback of the changes made by the transaction.

supports

public boolean supports(ConfigAttribute attribute)
