Extending Application Builder

Abstract

We will begin with a review of ApplicationBuilder and the SearchAPI. We will look at what functionality is provided out of the box with these tools, and how you can extend them to suit the needs of your project. In the class we will load sample documents, build an application, then add features to the application by extending the code that is generated by ApplicationBuilder. By the end of the afternoon session you will have used our best practices for extending the functionality of this powerful tool.
