Interface Long2LongSortedMap.FastSortedEntrySet

All Superinterfaces:

Collection<Long2LongMap.Entry>, Iterable<Long2LongMap.Entry>, Long2LongMap.FastEntrySet, ObjectBidirectionalIterable<Long2LongMap.Entry>, ObjectCollection<Long2LongMap.Entry>, ObjectIterable<Long2LongMap.Entry>, ObjectSet<Long2LongMap.Entry>, ObjectSortedSet<Long2LongMap.Entry>, SequencedCollection<Long2LongMap.Entry>, SequencedSet<Long2LongMap.Entry>, Set<Long2LongMap.Entry>, SortedSet<Long2LongMap.Entry>

Enclosing interface:

Long2LongSortedMap

public static interface Long2LongSortedMap.FastSortedEntrySet
extends ObjectSortedSet<Long2LongMap.Entry>, Long2LongMap.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<Long2LongMap.Entry>	fastIterator()	Returns a fast iterator over this entry set; the iterator might return always the same entry instance, suitably mutated.
ObjectBidirectionalIterator<Long2LongMap.Entry>	fastIterator(Long2LongMap.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<Long2LongMap.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 Long2LongMap.FastEntrySet

Returns:

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

fastIterator

ObjectBidirectionalIterator<Long2LongMap.Entry> fastIterator(Long2LongMap.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.
