Polymorphism Framework
======================
This framework adds subtype polymorphism support to SC.Record relationships and
SC.Store\#find.
## Using the Framework
In order to use the polymorphism for your record type, you need to set
the `isPolymorphic` property:
MyApp.SomeRecord = SC.Record.extend({
// your code here
});
MyApp.SomeRecord.isPolymorphic = YES;
## Example
YourApp.Person = SC.Record.extend();
YourApp.Person.isPolymorphic = YES;
YourApp.Male = YourApp.Person.extend({
isMale: YES
});
YourApp.Female = YourApp.Person.extend({
isFemale: YES
});
YourApp.store.createRecord(YourApp.Male, {
guid: '1'
});
YourApp.store.createRecord(YourApp.Female, {
guid: '2'
});
// SC.Store#find now returns records of the expected type
SC.Logger.log(SC.kindOf(YourApp.store.find(YourApp.Person, '1'), YourApp.Male)); // true
SC.Logger.log(SC.kindOf(YourApp.store.find(YourApp.Person, '2'), YourApp.Female)); // true
