Diviner Arcanist Tech Docs PhutilTypeSpec

final class PhutilTypeSpec
Arcanist Technical Documentation ()

Perform type checks using a simple type grammar. The grammar supports the following basic types:

int
float
bool
string
null
callable
regex
wild
AnyClassOrInterfaceName

It supports the following complex types:

list<type>
map<type, type>
type|type

A type may be marked as optional by suffixing it with "?" or prefixing it with the word "optional":

int?
optional int

A type may have a human-readable comment in parentheses, at the end:

int (must be even)

For example, these are valid type specifications:

int|string
map<int, bool>
list<list<wild>>
optional int
string (uppercase)

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters

string	$key	Name of the constant.
int\|null	$byte_limit	Maximum number of bytes permitted in the value.

Return

string

Value of the constant.

private function __construct()

This method is not documented.

Return

this	//Implicit.//

public function getType()
