| 成员名称 | 说明 | |
|---|---|---|
| CreateAndRegister | Create a stream and register its name so that it can be returned through the SOAP API for subsequent client requests. The first stream registered is the primary output stream. | |
| CreateForPersistedStreams | Create a single persisted stream for users who use the rs:PersistStream=true URL access option. When this option is used, no secondary streams are registered. Instead, the stream data is transmitted one chunk at a time, and user access the next data chunk in the persisted stream by using the same URL access command with the rs:GetNextStream=true option. This option is only applicable to URL access. | |
| CreateOnly | Only create a stream. This feature is used to create temporary streams that can be used by the rendering extension to handle large memory requirements. This temporary stream is not available for subsequent client requests. | |
| RegisterOnly | Register the stream as a secondary stream for the rendering extension. The method does not create a stream, but instead, the callback returns nullnull 引用（在 Visual Basic 中为 Nothing） and registers the name. |
