Return	Method	Summary
static<E extends Enum<E>>EnumSet<E>	allOf(Class<E> elementType)	Creates an enum set containing all of the elements in the specified element type.
EnumSet<E>	clone()	Returns a copy of this set.
static<E extends Enum<E>>EnumSet<E>	complementOf(EnumSet<E> s)	Creates an enum set with the same element type as the specified enum set, initially containing all the elements of this type that are not contained in the specified set.
static<E extends Enum<E>>EnumSet<E>	copyOf(Collection<E> c)	Creates an enum set initialized from the specified collection.
static<E extends Enum<E>>EnumSet<E>	copyOf(EnumSet<E> s)	Creates an enum set with the same element type as the specified enum set, initially containing the same elements (if any).

static<E extends Enum<E>>EnumSet<E>	of(E e)	Creates an enum set initially containing the specified element.
static<E extends Enum<E>>EnumSet<E>	of(E first, E... rest)	Creates an enum set initially containing the specified elements.
static<E extends Enum<E>>EnumSet<E>	of(E e1, E e2)	Creates an enum set initially containing the specified elements.
static<E extends Enum<E>>EnumSet<E>	of(E e1, E e2, E e3)	Creates an enum set initially containing the specified elements.
static<E extends Enum<E>>EnumSet<E>	of(E e1, E e2, E e3, E e4)	Creates an enum set initially containing the specified elements.
static<E extends Enum<E>>EnumSet<E>	of(E e1, E e2, E e3, E e4, E e5)	Creates an enum set initially containing the specified elements.
