Traits

A class that can be instantiated or replaced via DI

Properties

protected ValidationResult $result

The contained ValidationResult related to this error

Methods

public static 
create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

public static 
singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

public
__construct(ValidationResult|string $result = null, int $code = 0)

Construct a new ValidationException with an optional ValidationResult object

public
getResult()

Details

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

__construct(ValidationResult|string $result = null, int $code = 0)

Construct a new ValidationException with an optional ValidationResult object

Parameters

ValidationResult|string $result

The ValidationResult containing the failed result, or error message to build error from

int $code

The error code number

ValidationResult getResult()

Retrieves the ValidationResult related to this error

Return Value

ValidationResult
