MapKeys[K: K, V: V, H: HashFunction[K] val, M: HashMap[K, V, H] #read]¶
An iterator over the keys in a map.
- Iterator[M->K] ref
Creates an iterator for the given map.
- map: M
- MapKeys[K, V, H, M] ref^
True if it believes there are remaining entries. May not be right if values were added or removed from the map.
- Bool val
Returns the next key, or raises an error if there isn't one. If keys are added during iteration, this may not return all keys.
- M->K ?
