This class defines an abstract interface for output streams.
Classes inheriting this class can be used to write bytes to files, sockets, memory etc.
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.

Flushes any buffered (unwritten) bytes, closes the output stream and releases all resources.
Any methods called on a closed output stream will throw an exception.
Implemented in Qore::BinaryOutputStream, Qore::EncodingConversionOutputStream, Qore::FileOutputStream, Qore::PipeOutputStream, Qore::StderrOutputStream, Qore::StdoutOutputStream, Qore::StringOutputStream, and Qore::TransformOutputStream.
Qore::OutputStream::constructor | ( | ) |
