Constructor Detail

EnumMultiset

private EnumMultiset(java.lang.Class<E> type)

Creates an empty EnumMultiset.

Method Detail

create

public static <E extends java.lang.Enum<E>> EnumMultiset<E> create(java.lang.Class<E> type)

Creates an empty EnumMultiset.

create

public static <E extends java.lang.Enum<E>> EnumMultiset<E> create(java.lang.Iterable<E> elements)

Creates a new EnumMultiset containing the specified elements.

This implementation is highly efficient when elements is itself a Multiset.

Parameters:

elements - the elements that the multiset should contain

Throws:

java.lang.IllegalArgumentException - if elements is empty

create

public static <E extends java.lang.Enum<E>> EnumMultiset<E> create(java.lang.Iterable<E> elements,
                                                                   java.lang.Class<E> type)

Returns a new EnumMultiset instance containing the given elements. Unlike create(Iterable), this method does not produce an exception on an empty iterable.
