In 2.1, the ThemeView is merely a small wrapper around View with extra paths set. Merging these two classes means there is one less property for developers to set to enable themes in their applications.

/**
|
|
* View, the V in the MVC triad. View interacts with Helpers and view variables passed
|
|
* in from the controller to render the results of the controller action. Often this is HTML,
|
|
* but can also take the form of JSON, XML, PDF's or streaming files.
|
|
*
|
|
* CakePHP uses a two-step-view pattern. This means that the view content is rendered first,
|
|
* and then inserted into the selected layout. This also means you can pass data from the view to the
|
|
* layout using `$this->set()`
|
|
*
|
|
* Since 2.1, the base View class also includes support for themes by default. Theme views are regular
|
|
* view files that can provide unique HTML and static assets. If theme views are not found for the
|
|
* current view the default app view files will be used. You can set `$this->theme = 'mytheme'`
|
|
* in your Controller to use the Themes.
|
|
*
|
|
* Example of theme path with `$this->theme = 'SuperHot';` Would be `app/View/Themed/SuperHot/Posts`
