java.util.Iterator	keyIterator() An iterator over all keys of this map.
java.util.Set	keySet() A mutable set of keys of this map.
void	remove(java.lang.Object key) Removes the specified key from this map.
int	size() The size of this map.
java.lang.String	toString() A textual representation of this map.
java.util.Map	unmodifiableMap() An unmodifiable view to the internal map.
java.util.Iterator	valueIterator() An iterator over all values of this map.
protected abstract boolean	valuePredicate(java.lang.Object value) True iff the value satisfies the typing constraints.
