Class GrantedAuthorityEffectiveAclsResolver

java.lang.Object
  org.acegisecurity.acl.basic.GrantedAuthorityEffectiveAclsResolver

All Implemented Interfaces:: EffectiveAclsResolver

public class GrantedAuthorityEffectiveAclsResolver
extends java.lang.Object
implements EffectiveAclsResolver

Simple implementation of EffectiveAclsResolver.

This implementation does not need to understand the "recipient" types presented in a BasicAclEntry because it merely delegates to the detected Authentication.getPrincipal()>Authentication.getPrincipal() 55 or Authentication.getAuthorities()>Authentication.getAuthorities() 55 . The principal object or granted authorities object has its Object.equals(recipient) method called to make the decision as to whether the recipient in the BasicAclEntry is the same as the principal or granted authority.

This class should prove an adequate ACLs resolver if you're using standard Acegi Security classes. This is because the typical Authentication token is UsernamePasswordAuthenticationToken, which for its principal is usually a String. The GrantedAuthorityImpl is typically used for granted authorities, which tests for equality based on a String. This means BasicAclDaos simply need to return a String to represent the recipient. If you use non-String objects, you will probably require an alternative EffectiveAclsResolver.
