Interface AfterInvocationManager

All Known Implementing Classes:

AfterInvocationProviderManager

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.

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.

Method Summary

Modifier and Type	Method and Description
java.lang.Object	decide(Authentication authentication, java.lang.Object object, java.util.Collection<ConfigAttribute> attributes, java.lang.Object returnedObject) Given the details of a secure object invocation including its returned Object, make an access control decision or optionally modify the returned Object.
boolean	supports(java.lang.Class<?> clazz) Indicates whether the AfterInvocationManager implementation is able to provide access control decisions for the indicated secured object type.
boolean	supports(ConfigAttribute attribute) Indicates whether this AfterInvocationManager is able to process "after invocation" requests presented with the passed ConfigAttribute.

Method Detail

decide

java.lang.Object decide(Authentication authentication,
                        java.lang.Object object,
                        java.util.Collection<ConfigAttribute> attributes,
                        java.lang.Object returnedObject)
                 throws AccessDeniedException

Given the details of a secure object invocation including its returned Object, make an access control decision or optionally modify the returned Object.

Parameters:

authentication - the caller that invoked the method

object - the secured object that was called

attributes - the configuration attributes associated with the secured object that was invoked

returnedObject - the Object that was returned from the secure object invocation

Returns:

the Object that will ultimately be returned to the caller (if an implementation does not wish to modify the object to be returned to the caller, the implementation should simply return the same object it was passed by the returnedObject method argument)

Throws:

AccessDeniedException - if access is denied

supports

boolean supports(ConfigAttribute attribute)

Indicates whether this AfterInvocationManager is able to process "after invocation" requests presented with the passed ConfigAttribute.

This allows the AbstractSecurityInterceptor to check every configuration attribute can be consumed by the configured AccessDecisionManager and/or RunAsManager and/or AfterInvocationManager.

Parameters:

attribute - a configuration attribute that has been configured against the AbstractSecurityInterceptor

Returns:

true if this AfterInvocationManager can support the passed configuration attribute

supports

boolean supports(java.lang.Class<?> clazz)

Indicates whether the AfterInvocationManager implementation is able to provide access control decisions for the indicated secured object type.

Parameters:

clazz - the class that is being queried

Returns:

true if the implementation can process the indicated class
