Code example:

# insert elements
hash := Collection.Hash->New()<IntRef, String>;
hash->Insert(415, "San Francisco");
hash->Insert(510, "Oakland");
hash->Insert(925, "East Bay");

# get size
hash->Size()->PrintLine();

# get value by key
hash->Find(510)->PrintLine();

# get key/values
key_values := hash->GetKeyValues()<Pair<IntRef, String>>;
each(key_value := key_values) {
   key_value->GetFirst()->PrintLine();
};

# get values
values := hash->GetValues()<String>;
each(value := values) {
   value->PrintLine();
};

# check for key
hash->Has(408)->PrintLine();
