Methods and interface objects used to interact with external apis.
|
|
|
|
API method calls return objects that are in many cases objects with
|
|
attributes that are direct maps to the data returned from the API http call.
|
|
Unfortunately, these objects are also often constructed dynamically, making
|
|
it difficult to know what data is available from the API object. Because of
|
|
this, all API calls should wrap their returned object in one defined here,
|
|
using only explicitly defined atributes and/or methods.
|
|
|
|
In other words, django_openstack developers not working on django_openstack.api
|
|
shouldn't need to understand the finer details of APIs for Nova/Glance/Swift et
|
|
al.
