This class defines an abstract interface for input streams.
Classes inheriting this class can be used to read bytes from various sources.
STREAM-THREAD-ERROR
to be thrown, unless the stream is handed off to another thread using the StreamBase::unassignThread() method in the thread that currently owns the stream, and the StreamBase::reassignThread() method in the new thread.Qore::InputStream::constructor | ( | ) |
