A text stream is an instance of os_tstream . os_tstream is derived from the standard iostream class and thus inherits all of its behaviors. When an os_tstream is constructed, it is associated with a particular I/O device via an intermediate adapter object called


os_adapter

. When an item is streamed to an os_tstream , the item is converted into a text format and then sent to the I/O device via the adapter. This technique allows the text streaming mechanism to be fully decoupled from details of any particular I/O device.
