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.】
