Properties:

• public abstract bool mutable { get; }
  Determines whether the call to set_value is legal assuming the iterator is valid. The value must not change in runtime hence the user of iterator may cache it.
• public abstract bool read_only { get; }
  Determines whether the call to unset is legal assuming the iterator is valid. The value must not change in runtime hence the user of iterator may cache it.
• public abstract bool valid { get; }
  Determines whether the call to get_key, get_value and set_value is legal. It is false at the beginning and after unset call and true otherwise.

Methods:

• public virtual bool @foreach (ForallMapFunc<K,V> f)
  Apply function to each element returned by iterator.
• public virtual A fold<A> (FoldMapFunc<A,K,V> f, owned A seed)
  Standard aggregation function.
• 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 bool has_next ()
  Checks whether there is a next entry in the iteration.
• public abstract bool next ()
  Advances to the next entry 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).
