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
