public final class RecordType
extends PrototypeObjectType

A record (structural) type.

Subtyping: The subtyping of a record type is defined via structural comparison of a record type's properties. For example, a record type of the form { a : TYPE_1 } is a supertype of a record type of the form { b : TYPE_2, a : TYPE_1 } because B can be assigned to A and matches all constraints. Similarly, a defined type can be assigned to a record type so long as that defined type matches all property constraints of the record type. A record type of the form { a : A, b : B } can be assigned to a record of type { a : A }.
