MapIterator

Object Hierarchy:

Description:

public interface MapIterator<K,V> : Object

An iterator over a map.

Gee's iterators are "on-track" iterators. They always point to an item except before the first call to next or first, or, when an item has been removed, until the next call to next or first.

Please note that when the iterator is out of track, neither get_key, get_value, set_value nor unset are defined and all will fail. After the next call to next or first, they will be defined again.

Methods:

public abstract bool next ()
Advances to the next entry in the iteration.
public abstract bool has_next ()
Checks whether there is a next entry in the iteration.
public abstract bool first ()
Rewinds to the first entry in the iteration.
public abstract K? get_key ()
Returns the current key in the iteration.
public abstract V? get_value ()
Returns the value associated with the current key in the iteration.
public abstract void set_value (V? value)
Sets the value associated with the current key in the iteration.
public abstract void unset ()
Unsets the current entry in the iteration. The cursor is set in an in-between state. get_key, get_value, set_value and unset will fail until the next move of the cursor (calling next or first).
