Specified by:

equals in interface Key

Overrides:

equals in class Object

Parameters:

o - object to compare to.

Returns:

true if o is the same or equivalent key, false otherwise.

hashCode

public int hashCode()

Description copied from interface: Key

Return the hashCode for the key.

Specified by:

hashCode in interface Key

Overrides:

hashCode in class Object

Returns:

the key's hashCode.
