/**
|
|
* The most common kind of controller; effectively a controller linked to a {@link DataObject}.
|
|
*
|
|
* ContentControllers are most useful in the content-focused areas of a site. This is generally
|
|
* the bulk of a site; however, they may be less appropriate in, for example, the user management
|
|
* section of an application.
|
|
*
|
|
* On its own, content controller does very little. Its constructor is passed a {@link DataObject}
|
|
* which is stored in $this->dataRecord. Any unrecognised method calls, for example, Title()
|
|
* and Content(), will be passed along to the data record,
|
|
*
|
|
* Subclasses of ContentController are generally instantiated by ModelAsController; this will create
|
|
* a controller based on the URLSegment action variable, by looking in the SiteTree table.
|
|
*
|
|
* @todo Can this be used for anything other than SiteTree controllers?
|
|
*

|
* @package cms
|
|
* @subpackage control
