Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Create a template from a string instead of a .ss file
Assign the list of active themes to apply.
Add to the list of active themes to apply
Traverses the given the given class context looking for candidate template names which match each item in the class hierarchy. The resulting list of template candidates may or may not exist, but you can invoke {SSViewer::chooseTemplate} on any list to determine the best candidate based on the current themes.
Check if rewrite hash links are enabled on this instance
Set if hash links are rewritten for this instance
Get default value for rewrite hash links for all modules
Set default rewrite hash links
Set the template parser that will be used in template generation
Returns true if at least one of the listed templates exists.
Call this to disable rewriting of links. This is useful in Ajax applications.
Clears all parsed template files in the cache folder.
Set the cache object to use when storing / retrieving partial cache blocks.
Get the cache object to use when storing / retrieving partial cache blocks.
Flag whether to include the requirements in this response.
An internal utility function to set up variables in preparation for including a compiled template, then do the include
The process() method handles the "meat" of the template processing.
Get the appropriate template to use for the named sub-template, or null if none are appropriate
Execute the given template, passing it the given data.
Execute the evaluated string, passing it the given data.
Parse given template contents
Returns the filenames of the template that will be rendered. It is a map that may contain 'Content' & 'Layout', and will have to contain 'main'
Return an appropriate base tag for the given template.
Return an appropriate base tag for the given template.

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
uninherited(string $name)
Gets the uninherited value for the given config option
static Injectable
create(mixed ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

DBHTMLText
process(ViewableData $item, array|null $arguments = null, $scope = null)
The process() method handles the "meat" of the template processing.
It takes care of caching the output (via Cache), as well as replacing the special "$Content" and "$Layout" placeholders with their respective subtemplates.
The method injects extra HTML in the header via Requirements::includeInHTML().
Note: You can call this method indirectly by ViewableData->renderWith().
