Properties

Property	Modifier	Type	Description	Overrides	Inherited from
creating?	public	true	If the type is currently being created.	-	BaseType.creating
declarationKind	public	"extern" | "auto"	How this decorator was declared.	-	-
entityKind	readonly	"Type"	Distinguishes semantic types from values and parameter constraints.	-	BaseType.entityKind
implementation	public	(ctx, target, …args) => void	JavaScript implementation receiving the context, target, and marshalled custom arguments.	-	-
instantiationParameters?	public	Type[]	Legacy instantiation metadata. The compiler’s type checker does not populate this field, so its absence does not indicate whether this type is a template instance.	-	BaseType.instantiationParameters
isFinished	public	boolean	Reflect if a type has been finished(Decorators have been called). There is multiple reasons a type might not be finished: - a template declaration will not - a template instance that argument that are still template parameters - a template instance that is only partially instantiated(like a templated operation inside a templated interface)	-	BaseType.isFinished
kind	public	"Decorator"	Discriminant for decorator declarations rather than decorator applications.	BaseType.kind	-
name	public	`@${string}`	Local decorator name including its leading @, without namespace qualifiers.	-	-
namespace	public	Namespace	Declaring namespace, including the global namespace for unqualified declarations.	-	-
node?	public	DecoratorDeclarationStatementNode	Node used to construct this type. If the node is undefined it means the type was dynamically built. With typekit for example.	BaseType.node	-
parameters	public	MixedFunctionParameter[]	Custom parameter constraints in declaration order, excluding the target.	-	-
target	public	MixedFunctionParameter	Constraint on the decorated target, separate from custom arguments.	-	-
