#include <streamwriter.h>
Stream writer classes provide a specialized write-interface for a stream.
This is the abstract base class for all stream writers. It is possible to attach any number of readers and writers to the same stream.
Inherits Core::RefCounted.
Inherited by Http::HtmlPageWriter, Http::HttpRequestWriter, Http::HttpResponseWriter, Http::SvgPageWriter, IO::BinaryWriter, IO::JsonWriter, IO::TextWriter, IO::XmlWriter, and Messaging::MessageWriter.

end reading from the stream
Reimplemented in Http::HtmlPageWriter, Http::SvgPageWriter, IO::BinaryWriter, IO::JsonWriter, and IO::XmlWriter.
get currently set stream
Get pointer to the attached stream.
If there is no stream attached, an assertion will be thrown. Use HasStream() to determine if a stream is attached.
| bool IO::StreamWriter::HasStream | ( | ) | const |
return true if a stream is set
Returns true if a stream is attached to the writer.
|
inline |
return true if currently open
|
virtual |
begin reading from the stream
Reimplemented in Http::HtmlPageWriter, Http::SvgLineChartWriter, Http::SvgPageWriter, IO::BinaryWriter, IO::JsonWriter, and IO::XmlWriter.
set stream to write to
Attaches the writer to a stream.
This will imcrement the refcount of the stream.
