public class Int2CharRBTreeMap extends AbstractInt2CharSortedMap implements Serializable, Cloneable
The iterators provided by the views of this class are type-specific bidirectional iterators.
Moreover, the iterator returned by iterator()
can be safely cast
to a type-specific list iterator.

comparator()
Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
|
boolean |
containsKey(int k)
Checks whether the given value is contained in
AbstractInt2CharMap.keySet() . |
boolean |

Checks whether the given value is contained in
AbstractInt2CharMap.values() . |
int |
firstIntKey() |
char |
get(int k)
Returns the value to which the given key is mapped.

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
