Method Detail

decide

void decide(Authentication authentication,
            Object object,
            ConfigAttributeDefinition config)
            throws AccessDeniedException,
                   InsufficientAuthenticationException

Resolves an access control decision for the passed parameters.

Parameters:

authentication - the caller invoking the method

object - the secured object being called

config - 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
