[Solved] Custom Key for HashMap

Hey, so I’m using my own datatype for a key in a HashMap. Basically the idea is that you can send either an int or String (or both) to find a value. However, I never find values in my HashMap ???

Here’s what I have for the Key class:

public class Key
{
	public final int code;
	public final String name;

	public Key(int in_code, String in_name)
	{
		code = in_code;
		name = in_name;
	}

	public boolean equals(Object o)
	{
		if(o instanceof Key)
		{
			return code == ((Key) o).code && name.equals(((Key) o).name);
		}
		else if(o instanceof Integer)
		{
			return code == ((Integer) o).intValue();
		}
		else if(o instanceof String)
		{
			return name.equals(((String) o));
		}
		return false;
	}

	public int hashcode()
	{
		return (code << 16) + name.length();
	}
}

Here’s the map:

HashMap map = new HashMap<Key, InputOperation>();

and here is how I would like to use it:


m_map.get(97);
m_map.get("Print_Char");
m_map.get(new Key(97, "Print_Char"));

Edit: added new Key to the third get()…
