Class PolicyPredicateParser


  • public class PolicyPredicateParser
    extends java.lang.Object
    Default implementation of predicate parser. Limitations: 1. Currently parentheses are not suported. 2. Only , , , , and operators are supported. 3. The only boolean operators supported are AND and OR. AND takes precedence over OR. Example: a AND b OR e OR c AND d is treated as (a AND b) OR e OR (c AND d) 4. If this is n't adequate, roll your own.
