Interface Double2IntSortedMap.FastSortedEntrySet

All Superinterfaces:

Collection<Double2IntMap.Entry>, Double2IntMap.FastEntrySet, Iterable<Double2IntMap.Entry>, ObjectBidirectionalIterable<Double2IntMap.Entry>, ObjectCollection<Double2IntMap.Entry>, ObjectIterable<Double2IntMap.Entry>, ObjectSet<Double2IntMap.Entry>, ObjectSortedSet<Double2IntMap.Entry>, SequencedCollection<Double2IntMap.Entry>, SequencedSet<Double2IntMap.Entry>, Set<Double2IntMap.Entry>, SortedSet<Double2IntMap.Entry>

Enclosing interface:

Double2IntSortedMap

public static interface Double2IntSortedMap.FastSortedEntrySet
extends ObjectSortedSet<Double2IntMap.Entry>, Double2IntMap.FastEntrySet

A sorted entry set providing fast iteration.

In some cases (e.g., hash-based classes) iteration over an entry set requires the creation of a large number of entry objects. Some fastutil maps might return entry set objects of type FastSortedEntrySet: in this case, fastIterator() will return an iterator that is guaranteed not to create a large number of objects, possibly by returning always the same entry (of course, mutated).

Method Summary

Modifier and Type	Method	Description
ObjectBidirectionalIterator<Double2IntMap.Entry>	fastIterator()	Returns a fast iterator over this entry set; the iterator might return always the same entry instance, suitably mutated.
ObjectBidirectionalIterator<Double2IntMap.Entry>	fastIterator(Double2IntMap.Entry from)	Returns a fast iterator over this entry set, starting from a given element of the domain (optional operation); the iterator might return always the same entry instance, suitably mutated.

Method Details

fastIterator

ObjectBidirectionalIterator<Double2IntMap.Entry> fastIterator()

Returns a fast iterator over this entry set; the iterator might return always the same entry instance, suitably mutated.

Specified by:

fastIterator in interface Double2IntMap.FastEntrySet

Returns:

a fast iterator over this entry set; the iterator might return always the same Map.Entry instance, suitably mutated.

fastIterator

ObjectBidirectionalIterator<Double2IntMap.Entry> fastIterator(Double2IntMap.Entry from)

Returns a fast iterator over this entry set, starting from a given element of the domain (optional operation); the iterator might return always the same entry instance, suitably mutated.

Parameters:

from - an element to start from.

Returns:

a fast iterator over this sorted entry set starting at from; the iterator might return always the same entry object, suitably mutated.
