Usage

var anonymizer = new Anonymizer();

Basic

anonymizer.encode(data [,schema])

anonymizer.encode(
  {a: 1, b: true, c: 'test'},
  {a: 'Number', b: 'Boolean', c: 'String'}
);
=> [1, true, 'test']

anonymizer.encode(
  [{a: 1, b: true, c: 'test'}, {a: 2, b: false, c: 'test2'}],
  [{a: 'Number', b: 'Boolean', c: 'String'}]
);
=> [ [1, true, 'test'], [2, false, 'test2'] ]

anonymizer.decode(data [,schema])

anonymizer.decode(
  [1, true, 'test'],
  {a: 'Number', b: 'Boolean', c: 'String'}
);
=> {a: 1, b: true, c: 'test'}

anonymizer.decode(
  [ [1, true, 'test'], [2, false, 'test2'] ],
  [{a: 'Number', b: 'Boolean', c: 'String'}]
);
=> [{a: 1, b: true, c: 'test'}, {a: 2, b: false, c: 'test2'}]

Categorical values

Anonymizer can map categorical values to/from integers.

anonymizer.encode('test', 'Category');
=> 1

anonymizer.encode(['test', 'test2', 'test'], 'Category');
=> [1, 2, 1]

anonymizer.getCategories();
=> ['test', 'test2']

// Create a new anonymizer and pass known categories
var anonymizer2 = new Anonymizer(anonymizer.getCategories());

anonymizer2.decode(1);
=> 'test'

anonymizer2.decode([1, 2, 1]);
=> ['test', 'test2', 'test']
