Examples of com.sun.xacml.cond.EvaluationResult

com.sun.xacml.cond.EvaluationResult
This is used in cases where a normal result is some AttributeValue, but if an attribute couldn't be resolved (or some other problem occurred), then a Status object needs to be returned instead. This is used instead of throwing an exception for performance, but mainly because failure to resolve an attribute is not an error case for the code, merely for the evaluation, and represents normal operation. Separate exception types will be added later to represent errors in pdp operation. @since 1.0 @author Seth Proctor
