@Beta @GwtCompatible(emulated=true) public abstract class ForwardingSortedMultiset<E> extends ForwardingMultiset<E> implements SortedMultiset<E>
Warning: The methods of ForwardingSortedMultiset forward
indiscriminately to the methods of the delegate. For example, overriding
ForwardingMultiset.add(Object, int) alone will not change the behavior of ForwardingCollection.add(Object),
which can lead to unexpected behavior. In this case, you should override add(Object) as
well, either providing your own implementation, or delegating to the provided standardAdd method.
The standard methods and any collection views they return are not guaranteed to be
thread-safe, even when all of the methods that they depend on are thread-safe.
Multiset.Entry<E>| Modifier and Type | Method and Description |
|---|---|
Comparator<? super E> |
comparator()
Returns the comparator that orders this multiset, or
Ordering.natural() if the natural ordering of the elements is used. |
SortedMultiset<E> |
descendingMultiset()
Returns a descending view of this multiset.
|
NavigableSet<E> |
elementSet()
Returns the set of distinct elements contained in this multiset.
|
Multiset.Entry<E> |
firstEntry()
Returns the entry of the first element in this multiset, or
null if
this multiset is empty. |
SortedMultiset<E> |
headMultiset(E upperBound,
BoundType boundType)
Returns a view of this multiset restricted to the elements less than
upperBound, optionally including upperBound itself. |
Multiset.Entry<E> |
lastEntry()
Returns the entry of the last element in this multiset, or
null if
this multiset is empty. |
Multiset.Entry<E> |
pollFirstEntry()
Returns and removes the entry associated with the lowest element in this
multiset, or returns
null if this multiset is empty. |
Multiset.Entry<E> |
pollLastEntry()
Returns and removes the entry associated with the greatest element in this
multiset, or returns
null if this multiset is empty. |
SortedMultiset<E> |
subMultiset(E lowerBound,
BoundType lowerBoundType,
E upperBound,
BoundType upperBoundType)
Returns a view of this multiset restricted to the range between
lowerBound and upperBound. |
SortedMultiset<E> |
tailMultiset(E lowerBound,
BoundType boundType)
Returns a view of this multiset restricted to the elements greater than
lowerBound, optionally including lowerBound itself. |

MultisetIf the element set supports any removal operations, these necessarily cause all occurrences of the removed element(s) to be removed from the multiset. Implementations are not expected to support the add operations, although this is possible.
A common use for the element set is to find the number of distinct
elements in the multiset: elementSet().size().

SortedMultisetupperBound, optionally including upperBound itself. The
returned multiset is a view of this multiset, so changes to one will be
reflected in the other. The returned multiset supports all operations that
this multiset supports.
The returned multiset will throw an IllegalArgumentException on
attempts to add elements outside its range.

of this multiset, so changes to one will be reflected in the other. The
returned multiset supports all operations that this multiset supports.
The returned multiset will throw an IllegalArgumentException on
attempts to add elements outside its range.
This method is equivalent to
tailMultiset(lowerBound, lowerBoundType).headMultiset(upperBound,
upperBoundType).
