Resource collections

[jkrumow]

Hey Josh,

we have another PR!

We have modified the data model to map all the properties of a relationship onto a resource collection.
So instead of using an NSArray there is now a class JSONAPIResourceCollection which contains all related resources but also stores links to self and related. It also behaves like an NSArray (indexed subscripting, enumeration etc).

Best regards

Thank you @tarbrain! I assume this is probably a breaking change to the API then? 😇 (Didn't take a close look yet)

Yes, the library user would have to change the relationships on their model objects from NSArray to JSONAPIResourceCollection.

But then it is possible to lazily load a resource graph by requesting a resource with only a shallow relationship node, and later on you can request the content of the collection by its links.

@tarbrain Cool cool, thanks! I will keep that in mind. One of my initial thoughts would be to keep the current naming for NSArray and make a new property/function for the JSONAPIResourceCollection as I don't like to introduce breaking changes but I will take a look and let you know my final thoughts 👌

[jkrumow]

There is an NSMutableArray property called resources inside the JSONAPIResourceCollection class.
It is also publicly accessible.

@tarbrain Perfect! That is good to know... That may be alright then ☺️
