Class Char2BooleanAVLTreeMap

All Implemented Interfaces:
Char2BooleanFunction, Char2BooleanMap, Char2BooleanSortedMap, Function<java.lang.Character,​java.lang.Boolean>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Character,​java.lang.Boolean>, java.util.function.IntPredicate, java.util.Map<java.lang.Character,​java.lang.Boolean>, java.util.SortedMap<java.lang.Character,​java.lang.Boolean>

public class Char2BooleanAVLTreeMap
extends AbstractChar2BooleanSortedMap
implements java.io.Serializable, java.lang.Cloneable
A type-specific AVL tree map with a fast, small-footprint implementation.

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.
