The Joomla MVC Design Pattern
Model-View-Controller (MVC) is a set of design patterns, that are used to separate the different layers of your application.
- The View displays the data of the model by passing it to a template. The view object can therefore access the data of the model. Joomla implements the basic functionality in the abstract JView class.
- The Model stores the data of the application, and contains the business logic. Joomla implements the basic functionality in the abstract JModel class.
- The Controller handles the user requests and evokes the model and the views to change it's state. Joomla implements the basic functionality in the JController class.
|display||Execute and display a template script.|
|assign||Assigns variables to the view script via differing strategies.|
|assignRef||Assign variable for the view (by reference).|
|escape||Escapes a value for output in a view script.|
|get||Method to get data from a registered model or a property of the view|
|getModel||Method to get the model object|
|getLayout||Get the layout.|
|getName||Method to get the view name|
|setModel||Method to add a model to the view. We support a multiple model single view system by which models are referenced by classname. A caveat to the classname referencing is that any classname prepended by JModel will be referenced by the name without JModel, eg. JModelCategory is just Category.|
|setLayout||Sets the layout name to use|
|setLayoutExt||Allows a different extension for the layout files to be used|
|setEscape||Sets the _escape() callback.|
|addTemplatePath||Adds to the stack of view script paths in LIFO order.|
|addHelperPath||Adds to the stack of helper script paths in LIFO order.|
|loadTemplate||Load a template file -- first look in the templates folder for an override|
