public class HashTable<K,V>

Example: Get the value for a key:

public static int main (string[] args) {
HashTable<string, string> table = new HashTable<string, string> (str_hash, str_equal);
table.insert ("1", "first string");
table.insert ("2", "second string");
table.insert ("3", "third string");

// Output: ``first string``
unowned string val = table.get ("1");
print ("%s\n", val);

// Output: ``second string``
val = table.get ("2");
print ("%s\n", val);

// Output: ``third string``
val = table.get ("3");
print ("%s\n", val);

// Output: ``(null)``
val = table.get ("4");
print ("%s\n", val);



HashTable<string, int> table2 = new HashTable<string, int> (str_hash, str_equal);
table2.insert ("1", 1);

// Output: ``1``
int val2 = table2.get ("1");
print ("%d\n", val2);

// Output: ``0``
val2 = table2.get ("2");
print ("%d\n", val2);


HashTable<string, int?> table3 = new HashTable<string, int?> (str_hash, str_equal);
table3.insert ("1", 1);

// Output: ``1``
int? val3 = table3.get ("1");
print ("%d\n", val3);

// Output: ``(null)``
val3 = table3.get ("2");
if (val3 == null) {
print ("(null)\n");
} else {
print ("%d\n", val3);
}

return 0;
}
