NullSecurityToken
class NullSecurityToken extends SecurityToken (View source)
Specialized subclass for disabled security tokens - always returns TRUE for token checks. Use through SecurityToken::disable().
Traits
Provides extensions to this object to integrate it with standard config API methods.
A class that can be instantiated or replaced via DI

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.
Gets a global token (or creates one if it doesnt exist already).
Globally disable the token (override with NullSecurityToken) implementation. Note: Does not apply for
Globally enable tokens that have been previously disabled through disable.
Returns the value of an the global SecurityToken in the current session
You can't disable an existing instance, it will need to be overwritten like this:
$old = SecurityToken::inst(); // isEnabled() returns true
SecurityToken::disable();
$new = SecurityToken::inst(); // isEnabled() returns falseCalled by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template

static Config_ForClass
config()
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).

static array
get_template_global_variables()
Called by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template
If the method to call is not included for a particular template variable, a method named the same as the template variable will be called
If the casting class is not specified for a particular template variable, ViewableData::$default_cast is used
The first letter of the template variable is case-insensitive. However the method name is always case sensitive.
