在VBA指针Pointer里提到了3个取地址函数,VarPtr、StrPtr、ObjPtr。 其中提到了我们只需要VarPtr函数,是可以获取StrPtr、ObjPtr返回的地址的。 在VARANT里,我们讲到了Variant这个类型,它可以保存任何的类型,通过它的一个转换,我们不就可以获取到数组的地址吗? 是的,我们只要把1个数组赋值给1个Vari
Side note: exposing as Pointer would not work. Because the struct might be passed by value and live in Dart memory instead of C memory, in which case it is backed by a TypedData rather than a Pointer. Array wraps either of those.Sign...

A pointer attribute can be applied as a type attribute; as a field attribute that applies to a structure member, union member, or parameter; or as a function attribute that applies to the function return type. The pointer attribute can also appear with the pointer_default keyword....
Used to determine whether the ActionScript 3.0, ActionScript 2.0, or ActionScript 1.0 format should be used when writing to, or reading from, a ByteArray instance. ByteArray position : uint Moves, or returns the current position, in bytes, of the file pointer into the ByteArray object. Byte...
除非特别注明,否则如果指定数组引用为 null,则此类中的方法都会抛出 NullPointerException 常用方法介绍 asList() 返回一个受指定数组支持的固定大小的列表。(对返回列表的更改会“直接写”到数组。)此方法同 Collection.toArray() 一起,充当了基于数组的 API 与基于 collection 的 API 之间的桥梁。返回的列表是可...
