    • hasPermission

      boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission)
      Determines whether the user has the given permission for the given domain object.
      Parameters:
      authentication - represents the user in question. Should not be null.
      targetDomainObject - the domain object for which permissions should be checked. May be null in which case implementations should return false, as the null condition can be checked explicitly in the expression.
      permission - a representation of the permission object as supplied by the expression system. Not null.
      Returns:
      true if the permission is granted, false otherwise
