public class LogicalOperationEvaluator
extends RegexBasedEvaluator

PropertyHelper.PropertyEvaluator that processes combinations of !, & (+ is also accepted for XML ease-of-use), ^ (XOR), and |, in descending priority. Probably only useful when used with NestedPropertyExpander which, when taken in conjunction with ConditionTypeEvaluator, will resolve nested conditions to true or false, allowing them to be processed by this little fellow. Grouping can be accomplished by means of nested property expressions.
