API Builder is a set of classes designed to facilitate the implementation of a RESTful API.
Two classes form the heart of API builder:
This class allows for easy construction of the URL which is to be requested for a call. Despite being a seemingly trivial task, with complicated APIs the number of in-URL arguments and parameters can become quite large.
Implementation of the HTTP client which interfaces with the remote server.
Supports the three most common HTTP methods, GET, POST, and DELETE, as well as any arbitrary methods required by the API.
Though not marked as abstract, ApiBuilder and ApiService are meant to be used as base classes on which implementations can build rather than directly. This allows for the tailoring of the building process to conform to a specific remote API.
