Types

type Int

type Int map[int]struct{}

Int 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) 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 (s 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) Int

Insert adds items to the set.

func (Int) Intersection

func (s 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 (s 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)

PopAny Returns a single element from the set.

func (Int) Union

func (s 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.

type String

type String map[string]struct{}

String sets.String is a set of strings, implemented via map[string]struct{} for minimal memory consumption.

func NewString

func NewString(items ...string) String

NewString creates a String from a list of values.

func StringKeySet

func StringKeySet(theMap interface{}) String

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

func (String) Delete

func (s String) Delete(items ...string) String

Delete removes all items from the set.

func (String) Difference

func (s String) Difference(s2 String) String

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 (String) Equal

func (s String) Equal(s2 String) 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 (String) Has

func (s String) Has(item string) bool

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

func (String) HasAll

func (s String) HasAll(items ...string) bool

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

func (String) HasAny

func (s String) HasAny(items ...string) bool

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

func (String) Insert

func (s String) Insert(items ...string) String

Insert adds items to the set.

func (String) Intersection

func (s String) Intersection(s2 String) String

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 (String) IsSuperset

func (s String) IsSuperset(s2 String) bool

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

func (String) Len

func (s String) Len() int

Len returns the size of the set.

func (String) List

func (s String) List() []string

List returns the contents as a sorted string slice.

func (String) PopAny

func (s String) PopAny() (string, bool)

PopAny Returns a single element from the set.

func (String) Union

func (s String) Union(s2 String) String

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 (String) UnsortedList

func (s String) UnsortedList() []string

UnsortedList returns the slice with contents in random order.
