                給定一組多種類型,一個通用基本類型是一個類型,組中的所有類型可以統一為: > Given a set of multiple types,a common base type is a type which all types of the set unify against: ~~~ class Base { public function new() { } } class Child1 extends Base { } class Child2 extends Base { } class Main { static public function main() { var a = [new Child1(), new Child2()]; $type(a); // Array<Base> } } ~~~ 雖然Base沒有被提到,Haxe編譯器可以推斷它為通用類型 Chid1 和 Child2 。Haxe編譯器使用這類的合一在如下的情況: * 數組聲明 * if/else * switch的case > Although Base is not mentioned, the Haxe Compiler manages to infer it as the common type of Child1 and Child2. The Haxe Compiler employs this kind of uni?cation in the following situations: > * array declarations > * if/else > * cases of a switch
