http://issues.apache.org/bugzilla/show_bug.cgi?id=37979 Summary: [collections] PredicateUtils.allPredicate() should not throw if 1 or 0 predicates Product: Commons Version: 3.2 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Collections AssignedTo: commons-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] PredicateUtils.allPredicate() throws IllegalArgumentException if array with one or zero predicates is given. This is bad, because when I make my list of predicates (for example, parsing some string) I have to explicitly check number of predicates in list. Current behaviour limits usages of method without reason. PredicateUtils.allPredicate() should return first element of array in case of array with one element, and PredicateUtils.allPredicate() should return truePredicate() in case of empty array. Similary, PredicateUtils.anyPredicate() should return first predicate of array in case of array with one element, and PredicateUtils.anyPredicate() should return falsePredicate() in case of empty array. PredicateUtils.onePredicate() ... PredicateUtils.nonePredicate() ... This is almost backward compatible change, because nobody either passes arrays with zero or one predicates to this method or checks for IllegalArgumentException. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
