DebugView
class DebugView (View source)
A basic HTML wrapper for stylish rendering of a development info view.
Used to output error messages, and test results.
Traits
Provides extensions to this object to integrate it with standard config API methods.
A class that can be instantiated or replaced via DI
Config options
| columns | int | Column size to wrap long strings to |
Properties
| protected static | $error_types | |||
| protected static | $unknown_error |
Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($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.
Render the information header for the view
Render an error.
Render a fragment of the a source file
Outputs a variable in a user presentable way
Similar to renderVariable() but respects debug() method on object if available

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).
string
Breadcrumbs()
Generate breadcrumb links to the URL path being displayed
string
renderHeader(HTTPRequest $httpRequest = null)
Render HTML header for development views
string
renderInfo(string $title, string $subtitle, string|bool $description = false)

Outputs a variable in a user presentable way
renderMessage($message, $caller, $showHeader = true)

string
debugVariable(mixed $val, array $caller, bool $showHeader = true)
