\doxysubsection{Detailed Description}
This class defines the API for single thread streams. 

Base class for stream classes which are not designed to be accessed from multiple threads; they have been implemented without locking for fast and efficient use when used from a single thread. For methods that would be unsafe to use in another thread, any use of such methods in threads other than the thread where the constructor was called will cause a {\ttfamily STREAM-\/\+THREAD-\/\+ERROR} to be thrown, unless the stream is handed off to another thread using the \mbox{\hyperlink{class_qore_1_1_stream_base_a017fc847a42d5c670cb9640a94522666}{Stream\+Base\+::unassign\+Thread()}} method in the thread that currently owns the stream, and the \mbox{\hyperlink{class_qore_1_1_stream_base_ab6b33cb1944c46aca8e9984ddfd65452}{Stream\+Base\+::reassign\+Thread()}} method in the new thread.
