|
static <E> PersistentHashSet.MutHashSet<E> |
emptyMutable(Equator<E> eq)
Works around some type inference limitations of Java 8.
|
Equator<E> |
equator()
Returns the Equator used by this set for equals comparisons and hashCodes
|
UnmodIterator<E> |
iterator()
Iterates over contents with no guarantees about their ordering.
|
PersistentHashSet.MutHashSet<E> |
mutable()
Returns a mutable version of this immutable set.
|
static <E> PersistentHashSet<E> |
of(Iterable<E> elements)
Returns a new PersistentHashSet of the values.

static <E> PersistentHashSet<E> |
ofMap(ImMap<E,?> map) |
PersistentHashSet<E> |
put(E o)
Adds an element, returning a modified version of the set (leaving the original set unchanged).
|
int |
size()
Returns the number of items in this collection or iterable.
|
PersistentHashSet<E> |
without(E key)
Removes this key from the set
