Method Detail

decide

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

This concrete implementation simply polls all configured AccessDecisionVoters and upon completion determines the consensus of granted against denied responses.

If there were an equal number of grant and deny votes, the decision will be based on the isAllowIfEqualGrantedDeniedDecisions() property (defaults to true).

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

configAttributes - the configuration attributes associated with the method being invoked

Throws:

AccessDeniedException - if access is denied

isAllowIfEqualGrantedDeniedDecisions

public boolean isAllowIfEqualGrantedDeniedDecisions()

setAllowIfEqualGrantedDeniedDecisions

public void setAllowIfEqualGrantedDeniedDecisions(boolean allowIfEqualGrantedDeniedDecisions)
