Set

Set is an abstract data type that can store unique values, without any particular order implementation in Go.

Except for reference document Set (abstract data type) to define functions , It also implements some useful functions. for example: Each, EachE, List, SortedList and so on.

Install

Using go get command to get the latest version

go get github.com/SeananXu/go-set

Import it with:

import "github.com/SeananXu/go-set"

and use set as the package name inside the code.

Example

Initialization

// interface set
interfaceSet := set.NewInterface()

// int set
intSet := set.NewInt()

// int8 set
int8Set := set.NewInt8()

// int16 set
int16Set := set.NewInt16()

// int32 set
int32Set := set.NewInt32()

// int64 set
int64Set := set.NewInt64()

// float32 set
float32Set := set.NewFloat32()

// float64 set
float64Set := set.NewFloat64()

// uint set
uintSet := set.NewUint()

// uint8 set
uint8Set := set.NewUint8()

// uint16 set
uint16Set := set.NewUint16()

// uint32 set
uint32Set := set.NewUint32()

// uint64 set
uint64Set := set.NewUint64()

// uintptr set
uintptrSet := set.NewUintptr()

// string set
stringSet := set.NewString()

Basic Operations

// add element
s.Add("element")

// remove element
s.Remove("element")

// pop element
k, ok := s.Pop()

// clear set
s.Clear()

// the number of elements
size := s.Size()

// clone new set
t := s.Copy()

// returns the all elements as a slice
t := s.List()

// returns the all elements as a slice sorted by less func
s.SortedList(func(i, j interface{}) bool {
    return false
})

// returns string
str := s.String()

Iterator Operations

s.Each(func(i interface{}) {
    log.Println(i)
})

s.EachE(func(i interface{}) error {
    log.Println(i)
    return set.ErrBreakEach
})

Check Operations

// whether the set is Empty
b := s.IsEmpty()

// whether element exists in set
b := s.Has("element")

// whether all elements exist in set
b := s.HasAll("element1", "element2")

// whether at least one of the element exists in the set
b := s.HasAny("element1", "element2")

// predicates that tests whether the set s is a subset of set t
b := s.IsSuperset(t)

// predicates that tests whether the set s is a super of set t
b := s.IsSubset(t)

// predicates that tests whether the set s equals of set t
b := s.Equal(t)

Set Operations

// returns the union of sets s and t
s.Union(t)

// returns the intersection of sets s and t
s.Intersection(t)

// returns the difference of sets s and t
s.Difference(t)

// returns the symmetric difference of sets s and t
s.SymmetricDifference(t)

Setgen

The Setgen command is used to generate source code for a set class given a type. It supports the following flags.

-s: Set name, default: element type add 's'.
-i: Import element package, default: don't import package.
-p: Generated go file package, default: directory name.
-t: Set storage element type, this options must be set.
-o: Output file name, default: set name add '.go'.
-l: Whether go file imports 'ErrBreakEach' of 'github.com/SeananXu/go-set', default: import.
-h: Help document.

Install

go get github.com/SeananXu/go-set/setgen
