Method Detail

decide

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

This concrete implementation polls all configured AccessDecisionVoters for each ConfigAttribute and grants access if only grant (or abstain) votes were received.

Other voting implementations usually pass the entire list of ConfigAttributes to the AccessDecisionVoter. This implementation differs in that each AccessDecisionVoter knows only about a single ConfigAttribute at a time.

If every AccessDecisionVoter abstained from voting, the decision will be based on the AbstractAccessDecisionManager.isAllowIfAllAbstainDecisions() property (defaults to false).

Parameters:

authentication - the caller invoking the method

object - the secured object

attributes - the configuration attributes associated with the method being invoked

Throws:

AccessDeniedException - if access is denied
