class CliDebugView extends DebugView (View source)

A basic HTML wrapper for stylish rendering of a development info view.

Used to output error messages, and test results.

Perhaps DebugView should be an interface / ABC, implemented by HTMLDebugView and CliDebugView?

Details

static Config_ForClass config()

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).

Return Value

Config_ForClass

mixed stat(string $name) deprecated

deprecated 5.0 Use ->config()->get() instead

Get inherited config value

Parameters

string $name

Return Value

mixed

mixed uninherited(string $name)

Gets the uninherited value for the given config option

Parameters

string $name

Return Value

mixed

$this set_stat(string $name, mixed $value) deprecated

deprecated 5.0 Use ->config()->set() instead

Update the config value for a given property

Parameters

string $name

Return Value

$this

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();

Parameters

mixed ...$args

Return Value

Injectable

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).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

string Breadcrumbs()

Generate breadcrumb links to the URL path being displayed

Return Value

string
