Custom Libraries Let your creativity run free when programming

Overview Objective Learn how to add your own custom libraries to ProdigyView. Requirements Understanding of PVCollection Understanding of PVStaticObject Estimated Time 10 Minutes www.prodigyview.com

Follow Along With Code Example Download a copy of the example code at www.prodigyview.com/source. Install the system in an environment you feel comfortable testing in. Proceed to examples/system/Custom_Libraries.php

Create A Collection First thing we need to do is create a collection. This collection is where we will store our libraries If you are familiar with the dynamic objects tutorial, then you remember how we can add variables to any object in ProdigyView.

Anonymous Functions 1 In our next step, we need to create an anonymous function that will add the library to our collection. Our custom libraries are going to have a name and a location. 1. Closure accepts the name and location as arguments 2. Pull the custom library object from PVLibraries 3. Add the name and location to the collection 4. Add the collection back in

Anonymous Function 2 Our second anonymous function will be used for retrieving the libraries added. 1. Pull your library collection 2. Return the iterator

Add The Functions Now all we have to do is add the anonymous functions to PVLibraries and we can begin to use our custom libraries. 1. Set the name of method in PVLibraries 2. Associate it with an anonymous function

Add Our Libraries The method addMyLibrary, which now a part of PVLibraries, is using the anonymous function we created before. Add you library and its location through this method. 1. Call Our New Method 2. Set our library name 3. Set the library location www.prodigyview.com

Iterate Through Our Libs Our last step in this process is iterating through the libraries that we added. Our results will show the name and location of our libraries. www.prodigyview.com Uses the anonymous function

Review What we did in this tutorial is combine a few different features of ProdigyView, and use them to expand the framework to fit our needs. PVLibraries extends PVStaticObject PVStaticObject has the ability to create new variables and methods PVCollection stores a list of data which can be iterated too. Almost every object in ProdigyView has the ability to be expanded as in this example. Keep your imagination open when programming.
