    An immutable SortedMultiset that stores its elements in a sorted array. Some instances are ordered by an explicit comparator, while others follow the natural sort ordering of their elements. Either way, null elements are not supported.

    Unlike Multisets.unmodifiableSortedMultiset(com.google.common.collect.SortedMultiset<E>), which is a view of a separate collection that can still change, an instance of ImmutableSortedMultiset contains its own private data and will never change. This class is convenient for public static final multisets ("constant multisets") and also lets you easily make a "defensive copy" of a set provided to your class by a caller.

    The multisets returned by the headMultiset(E, com.google.common.collect.BoundType), tailMultiset(E, com.google.common.collect.BoundType), and subMultiset(E, com.google.common.collect.BoundType, E, com.google.common.collect.BoundType) methods share the same array as the original multiset, preventing that array from being garbage collected. If this is a concern, the data may be copied into a correctly-sized array by calling copyOfSorted(com.google.common.collect.SortedMultiset<E>).

    Note on element equivalence: The ImmutableMultiset.contains(Object), ImmutableMultiset.containsAll(Collection), and ImmutableMultiset.equals(Object) implementations must check whether a provided object is equivalent to an element in the collection. Unlike most collections, an ImmutableSortedMultiset doesn't use Object.equals(java.lang.Object) to determine if two elements are equivalent. Instead, with an explicit comparator, the following relation determines whether elements x and y are equivalent:

       
    
        {(x, y) | comparator.compare(x, y) == 0}

    With natural ordering of elements, the following relation determines whether two elements are equivalent:

       
    
        {(x, y) | x.compareTo(y) == 0}
    Warning: Like most multisets, an ImmutableSortedMultiset will not function correctly if an element is modified after being placed in the multiset. For this reason, and to avoid general confusion, it is strongly recommended to place only immutable objects into this collection.

    Note: Although this class is not final, it cannot be subclassed as it has no public or protected constructors. Thus, instances of this type are guaranteed to be immutable.

        public static <E> ImmutableSortedMultiset<E> copyOf​(java.lang.Iterable<? extends E> elements)
        Deprecated.
        Returns an immutable sorted multiset containing the given elements sorted by their natural ordering. To create a copy of a SortedMultiset that preserves the comparator, call copyOfSorted(com.google.common.collect.SortedMultiset<E>) instead. This method iterates over elements at most once.

        Note that if s is a multiset<String>, then ImmutableSortedMultiset.copyOf(s) returns an ImmutableSortedMultiset<String> containing each of the strings in s, while ImmutableSortedMultiset.of(s) returns an ImmutableSortedMultiset<multiset<String>> containing one element (the given multiset itself).

        Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

        This method is not type-safe, as it may be called on elements that are not mutually comparable.

        Throws:
        java.lang.ClassCastException - if the elements are not mutually comparable

        This method is not type-safe, as it may be called on elements that are not mutually comparable.

        Throws:

        Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

        Throws:

      • copyOfSorted

        public static <E> ImmutableSortedMultiset<E> copyOfSorted​(SortedMultiset<E> sortedMultiset)
        Deprecated.
        Returns an immutable sorted multiset containing the elements of a sorted multiset, sorted by the same Comparator. That behavior differs from copyOf(Iterable), which always uses the natural ordering of the elements.

        Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

        This method is safe to use even when sortedMultiset is a synchronized or concurrent collection that is currently being modified by another thread.

        Throws:
        java.lang.NullPointerException - if sortedMultiset or any of its elements is null

        Description copied from interface: SortedMultiset
        Returns a view of this multiset restricted to the elements less than upperBound, 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.

        Returns a view of this multiset restricted to the range between lowerBound and upperBound. 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.

        This method is equivalent to tailMultiset(lowerBound, lowerBoundType).headMultiset(upperBound, upperBoundType).

      • orderedBy

        public static <E> ImmutableSortedMultiset.Builder<E> orderedBy​(java.util.Comparator<E> comparator)
        Deprecated.
        Returns a builder that creates immutable sorted multisets with an explicit comparator. If the comparator has a more general type than the set being generated, such as creating a SortedMultiset<Integer> with a Comparator<Number>, use the ImmutableSortedMultiset.Builder constructor instead.
        Throws:
        java.lang.NullPointerException - if comparator is null
      • reverseOrder

        public static <E extends java.lang.Comparable<E>> ImmutableSortedMultiset.Builder<E> reverseOrder()
        Deprecated.
        Returns a builder that creates immutable sorted multisets whose elements are ordered by the reverse of their natural ordering.

        Note: the type parameter E extends Comparable<E> rather than Comparable<? super E> as a workaround for javac bug 6468354.

      • naturalOrder

        public static <E extends java.lang.Comparable<E>> ImmutableSortedMultiset.Builder<E> naturalOrder()
        Deprecated.
        Returns a builder that creates immutable sorted multisets whose elements are ordered by their natural ordering. The sorted multisets use Ordering.natural() as the comparator. This method provides more type-safety than builder(), as it can be called only for classes that implement Comparable.

        Note: the type parameter E extends Comparable<E> rather than Comparable<? super E> as a workaround for javac bug 6468354.
