serializer._getSharedArrayBufferId(sharedArrayBuffer)

• sharedArrayBuffer <SharedArrayBuffer>

当序列化器要序列化一个 SharedArrayBuffer 对象时，将调用此方法。它必须为该对象返回一个无符号 32 位整数 ID，如果这个 SharedArrayBuffer 已经被序列化过，则使用相同的 ID。在反序列化时，这个 ID 将传递给 deserializer.transferArrayBuffer()。

🌐 This method is called when the serializer is going to serialize a SharedArrayBuffer object. It must return an unsigned 32-bit integer ID for the object, using the same ID if this SharedArrayBuffer has already been serialized. When deserializing, this ID will be passed to deserializer.transferArrayBuffer().

如果对象无法序列化，则应抛出异常。

🌐 If the object cannot be serialized, an exception should be thrown.

此方法本身并不存在于 Serializer 类中，但可以由子类提供。

🌐 This method is not present on the Serializer class itself but can be provided by subclasses.
