Usage

// use it as module
var Enum = require('enum');

// or extend node.js with this new type
require('enum').register();

// define a simple enum (automatically flaggable -> A: 0x01, B: 0x02, C: 0x04)
var myEnum = new Enum(['A', 'B', 'C']);

// define an enum with own values
var myEnum = new Enum({'A': 1, 'B': 2, 'C': 4});

// if defining an flaggable enum, you can define your own separator (default is ' | ')
var myEnum = new Enum(['A', 'B', 'C'], { separator: ' | ' });

// if you want your enum to have a name define it in the options
var myEnum = new Enum(['A', 'B', 'C'], { name: 'MyEnum' });

// or
var myEnum = new Enum(['A', 'B', 'C'], 'MyEnum');


// get your item
myEnum.A

// or
myEnum.get('A')

// or
myEnum.get(1)

// or
myEnum.get('A | B')

// or
myEnum.get(3)


// get your value
myEnum.A.value

// get your key
myEnum.A.key


// get all items
myEnum.enums // returns all enums in an array


// compare
myEnum.A.is(myEnum.A)

// or
myEnum.A.is('A')

// or
myEnum.A.is(1)

// or
myEnum.A == 'A'

// or
myEnum.A == myEnum.A

// or
myEnum.A === myEnum.A


// check flag
var myItem = myEnum.get(3); // or [myEnum.get('A | B')]
myItem.has(myEnum.A)

// or
myItem.has('A')

// or
myItem.has(1)


// other functions
myItem.toString() // returns A | C
myItem.toJSON() // returns A | C
myItem.valueOf() // returns A | C

JSON.stringify(myItem) // returns A | C
