Class Int2BooleanRBTreeMap

  • All Implemented Interfaces:
    Function<java.lang.Integer,​java.lang.Boolean>, Int2BooleanFunction, Int2BooleanMap, Int2BooleanSortedMap, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Integer,​java.lang.Boolean>, java.util.function.IntPredicate, java.util.Map<java.lang.Integer,​java.lang.Boolean>, java.util.SortedMap<java.lang.Integer,​java.lang.Boolean>

    public class Int2BooleanRBTreeMap
    extends AbstractInt2BooleanSortedMap
    implements java.io.Serializable, java.lang.Cloneable
    A type-specific red-black 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.

        Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

      • clone

        public Int2BooleanRBTreeMap clone()
        Returns a deep copy of this tree map.

        This method performs a deep copy of this tree map; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.

        Returns:
        a deep copy of this tree map.
