hashList function
Combine the Object.hashCode values of an arbitrary number of objects from an Iterable into one value. This function will return the same value if given null as if given an empty list.
Implementation
int hashList(Iterable<Object> arguments) {
int result = 0;
if (arguments != null) {
for (Object argument in arguments)
result = _Jenkins.combine(result, argument);
}
return _Jenkins.finish(result);
}
