Method Details
-
containsKey
Description copied from interface:Function
Returns true if this function contains a mapping for the specified key.Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.
- Specified by:
containsKey
in interfaceFunction<K,Integer>
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key
