decide

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

This concrete implementation simply polls all configured AccessDecisionVoters and grants access if any AccessDecisionVoter voted affirmatively. Denies access only if there was a deny vote AND no affirmative votes.

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

config - the configuration attributes associated with the method being invoked

Throws:

AccessDeniedException - if access is denied
