java - Validation of Apache Commons Configuration Values -

-

i'm using apache's commons-configuration (v 1.10) library provide configuration values program. use compositeconfiguration of systemconfiguration , propertiesconfiguration in order allow users override properties file java's -d command-line argument.

the problem i'm running validation of values in configuration (ensure value of x positive, example). near can tell, commons-configuration library (neither 1.10 nor 2.0-beta) not provide means of validating configuration values. yes, can validate xml document that's used xmlconfiguration (and that's hear if try google answer question). doesn't me values come systemconfiguration part of configuration class.

so, missing something? library provide way validate values i'm missing, or there java library that's built on commons-configuration provides validation capabilities? or need build derivative of compositeconfiguration?

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
