Ember.Copyable Class packages/ember-runtime/lib/mixins/copyable.js:16
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
frozenCopy() will only work if you also implement
Override to return a copy of the receiver. Default implementation raises an exception.
- deep Boolean
- if `true`, a deep copy of the object should be made
- copy of receiver
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.
- copy of receiver or receiver
