Ember.Copyable Class packages/ember-runtime/lib/mixins/copyable.js:12
PRIVATE
Defined in: packages/ember-runtime/lib/mixins/copyable.js:12
Module: ember-runtime
Implements some standard methods for copying an object. Add this mixin to any object you create that can create a copy of itself. This mixin is added automatically to the built-in array.
You should generally implement the copy() method to return a copy of the
receiver.
Note that frozenCopy() will only work if you also implement
Ember.Freezable.
copy
(deep)
Object
private
Required. You must implement this method to apply this mixin.
Override to return a copy of the receiver. Default implementation raises an exception.
Parameters:
- deep Boolean
- if `true`, a deep copy of the object should be made
Returns:
- Object
- copy of receiver
frozenCopy
Object
deprecated
private
Use Object.freeze instead.
If the object implements Ember.Freezable, then this will return a new
copy if the object is not frozen and the receiver if the object is frozen.
Raises an exception if you try to call this method on a object that does not support freezing.
You should use this method whenever you want a copy of a freezable object since a freezable object can simply return itself without actually consuming more memory.
Returns:
- Object
- copy of receiver or receiver
