ActionScript 3 Client Library

Created Feb 6, 2015 11:22:56 AM for Adobe Flex.


The ActionScript client bundle is an SWC containing the ActionScript classes that can be used with Adobe Flex to develop, for example, a Flash UI that interfaces with this public API. The ActionScript classes have been generated with an emphasis on usability, clarity, and type safety (inasmuch as ActionScript allows it). All public data types have been generated along with the services (if any) that access them.

For any services, this means that rather than using a standard RemoteObject, you can instantiate a service, register the appropriate events, and invoke the method. The service will fire the appropriate (strongly-typed) event that contains the response. Because the public client-side data types are also generated for ActionScript developers, these can be used to read and invoke any REST endpoints that provide the AMF content type (e.g. "application/x-amf").

C Client Library

Created Feb 6, 2015 11:22:33 AM.


The C module generates the source code for the ANSI-C-compatible data structures and (de)serialization functions that can be used in conjunction with libxml2 to (de)serialize the REST resources as they are represented as XML data.

The generated C source code depends on the XML Reader API and the XML Writer API as well as the <time.h>, <string.h>, and <stdlib.h> C standard libraries.

.NET Client Library

Objective C Client Library

Created Feb 6, 2015 11:22:36 AM.


The Objective C module generates the source code for the Objective C classes and (de)serialization functions that can be used in conjunction with libxml2 to (de)serialize the REST resources as they are represented as XML data.

The generated Objective C source code depends on the XML Reader API and the XML Writer API as well as the base OpenStep foundation classes.

Ruby Client Library

Created Feb 6, 2015 11:22:36 AM for Ruby.


The Ruby client-side library defines the Ruby classes that can be (de)serialized to/from JSON. This is useful for accessing the REST endpoints that are published by this application, but only those that produce a JSON representation of their resources (content type "application/json").

This library leverages the Ruby JSON Implementation, which is required in order to use this library.
