Method Detail

decide

void decide(Authentication authentication,
            Object object,
            Collection<ConfigAttribute> configAttributes)
            throws AccessDeniedException,
                   InsufficientAuthenticationException
Resolves an access control decision for the passed parameters.

Parameters:
authentication - the caller invoking the method (not null)
object - the secured object being called
configAttributes - the configuration attributes associated with the secured object being invoked
Throws:
AccessDeniedException - if access is denied as the authentication does not hold a required authority or ACL privilege
InsufficientAuthenticationException - if access is denied as the authentication does not provide a sufficient level of trust

supports

boolean supports(ConfigAttribute attribute)
Indicates whether this AccessDecisionManager is able to process authorization 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 AccessDecisionManager can support the passed configuration attribute

supports

boolean supports(Class<?> clazz)
Indicates whether the AccessDecisionManager 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
