Types

type Empty

type Empty struct{}

Empty is public since it is used by some internal API objects for conversions between external string arrays and internal sets, and conversion logic requires public types today.

type Int

type Int map[int]Empty

sets.Int is a set of ints, implemented via map[int]struct{} for minimal memory consumption.

func IntKeySet

func IntKeySet(theMap interface{}) Int

IntKeySet creates a Int from a keys of a map[int](? extends interface{}). If the value passed in is not actually a map, this will panic.

func NewInt

func NewInt(items ...int) Int

NewInt creates a Int from a list of values.

func (Int) Delete

func (s Int) Delete(items ...int)

Delete removes all items from the set.

func (Int) Difference

func (s Int) Difference(s2 Int) Int

Difference returns a set of objects that are not in s2 For example: s1 = {a1, a2, a3} s2 = {a1, a2, a4, a5} s1.Difference(s2) = {a3} s2.Difference(s1) = {a4, a5}

func (Int) Equal

func (s1 Int) Equal(s2 Int) bool

Equal returns true if and only if s1 is equal (as a set) to s2. Two sets are equal if their membership is identical. (In practice, this means same elements, order doesn't matter)

func (Int) Has

func (s Int) Has(item int) bool

Has returns true if and only if item is contained in the set.

func (Int) HasAll

func (s Int) HasAll(items ...int) bool

HasAll returns true if and only if all items are contained in the set.

func (Int) HasAny

func (s Int) HasAny(items ...int) bool

HasAny returns true if any items are contained in the set.

func (Int) Insert

func (s Int) Insert(items ...int)

Insert adds items to the set.

func (Int) Intersection

func (s1 Int) Intersection(s2 Int) Int

Intersection returns a new set which includes the item in BOTH s1 and s2 For example: s1 = {a1, a2} s2 = {a2, a3} s1.Intersection(s2) = {a2}

func (Int) IsSuperset

func (s1 Int) IsSuperset(s2 Int) bool

IsSuperset returns true if and only if s1 is a superset of s2.

func (Int) Len

func (s Int) Len() int

Len returns the size of the set.

func (Int) List

func (s Int) List() []int

List returns the contents as a sorted int slice.

func (Int) PopAny

func (s Int) PopAny() (int, bool)

Returns a single element from the set.

func (Int) Union

func (s1 Int) Union(s2 Int) Int

Union returns a new set which includes items in either s1 or s2. For example: s1 = {a1, a2} s2 = {a3, a4} s1.Union(s2) = {a1, a2, a3, a4} s2.Union(s1) = {a1, a2, a3, a4}

func (Int) UnsortedList

func (s Int) UnsortedList() []int

UnsortedList returns the slice with contents in random order.
