#endpoints=(endpoints) ⇒ Object

Add all Endpoint objects within this Bubbles::Configuration instance.

Endpoint objects are defined using two required parameters: type and location, and three optional parameters: authenticated, api_key_required and name.

- method: Indicates the HTTP method used to access the endpoint. Must be one of {Endpoint::METHODS}.
- location: Indicates the path at which the {Endpoint} can be accessed on the host environment.
- authenticated: (Optional) A true or false value indicating whether the {Endpoint} requires an authorization
                 token to access it. Defaults to false.
- api_key_required: (Optional) A true or false value indicating whether the {Endpoint} requires a API key to
                    access it. Defaults to false.
- name: (Optional): A +String+ indicating the name of the method to add. If not provided, the method name will
        be the same as the +location+.

#environment ⇒ Object

Retrieve the RestEnvironment object defined as part of this Configuration.

Note that this constructs a new RestEnvironment and returns it, rather than returning an existing object.

# File 'lib/bubbles/config.rb', line 55

def environment
  RestEnvironment.new(@environment_scheme, @environment_host, @environment_port, @environment_api_key)
end

#environment=(env) ⇒ Object

Set the current environment.

Examples:

In app/config/environments/staging.rb:

Bubbles.configure do |config|
  config.environment = {
     :scheme => 'https',
     :host => 'stage.api.somehost.com',
     :port => '443'
  }
end

Parameters:

  • env (Object) —

    The environment, as a generic Ruby Object.
