Overview

Package hashmap implements a map backed by a hash table.

Elements are unordered in the map.

Structure is not thread safe.

Types

type Map

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

Map holds the elements in go's native map

func New

func New() *Map

New instantiates a hash map.

func (*Map) Clear

func (m *Map) Clear()

Clear removes all elements from the map.

func (*Map) Empty

func (m *Map) Empty() bool

Empty returns true if map does not contain any elements

func (*Map) FromJSON

func (m *Map) FromJSON(data []byte) error

FromJSON populates list's elements from the input JSON representation.

func (*Map) Get

func (m *Map) Get(key interface{}) (value interface{}, found bool)

Get searches the element in the map by key and returns its value or nil if key is not found in map. Second return parameter is true if key was found, otherwise false.

func (*Map) Keys

func (m *Map) Keys() []interface{}

Keys returns all keys (random order).

func (*Map) Put

func (m *Map) Put(key interface{}, value interface{})

Put inserts element into the map.

func (*Map) Remove

func (m *Map) Remove(key interface{})

Remove removes the element from the map by key.

func (*Map) Size

func (m *Map) Size() int

Size returns number of elements in the map.

func (*Map) String

func (m *Map) String() string

String returns a string representation of container

func (*Map) ToJSON

func (m *Map) ToJSON() ([]byte, error)

ToJSON outputs the JSON representation of list's elements.

func (*Map) Values

func (m *Map) Values() []interface{}

Values returns all values (random order).
