classTypeDirectiveReader
final class TypeDirectiveReader
implements BisonDirectiveReaderRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Reads %type, which gives rules the semantic type their values carry.
The type tag is what the directive exists for, so a %type without one declares nothing and is reported as absent rather than as an empty list.
Methods§
public function __construct(BisonDeclarationBoundary|null $boundary = null)Parameters
$boundary | BisonDeclarationBoundary|null | Decides where the declaration ends |
