#compute_url!(params) ⇒ Object

Computes the url from params by identifiying endpoint and compiles it if necessary. Id in params is threaded in a special way.

def compute_url!(params)

  url
end

#endpoint(url, options = nil) ⇒ Object

Adds the endpoint to the list of endpoints.

#find_endpoint(params = {}) ⇒ Object

Find an endpoint based on the provided parameters. If no parameters are provided it finds the base endpoint otherwise it finds the endpoint that matches the parameters best.
