Types

type Set

type Set struct {
	// contains filtered or unexported fields
}

Set holds elements in go's native map

func New

func New(values ...interface{}) *Set

New instantiates a new empty set and adds the passed values, if any, to the set

func (*Set) Add

func (set *Set) Add(items ...interface{})

Add adds the items (one or more) to the set.

func (*Set) Clear

func (set *Set) Clear()

Clear clears all values in the set.

func (*Set) Contains

func (set *Set) Contains(items ...interface{}) bool

Contains check if items (one or more) are present in the set. All items have to be present in the set for the method to return true. Returns true if no arguments are passed at all, i.e. set is always superset of empty set.

func (*Set) Empty

func (set *Set) Empty() bool

Empty returns true if set does not contain any elements.

func (*Set) FromJSON

func (set *Set) FromJSON(data []byte) error

FromJSON populates the set from the input JSON representation.

func (*Set) Remove

func (set *Set) Remove(items ...interface{})

Remove removes the items (one or more) from the set.

func (*Set) Size

func (set *Set) Size() int

Size returns number of elements within the set.

func (*Set) String

func (set *Set) String() string

String returns a string representation of container

func (*Set) ToJSON

func (set *Set) ToJSON() ([]byte, error)

ToJSON outputs the JSON representation of the set.

func (*Set) Values

func (set *Set) Values() []interface{}

Values returns all items in the set.
