public class StreamTargetFactory

extends AbstractTargetFactory

implements Contextualizable

TargetFactory for StreamTarget. This factory is able to create different StreamTargets according to the following configuration syntax:

 <stream id="foo">
  <stream>stream-context-name</stream>
  <format type="raw|pattern|extended">pattern to be used if needed</format>
 </stream>
 

The "stream-context-name" is the name of an java.io.OutputStream that is fetched in the context. This context contains two predefined streams :

"System.out" for the system output stream,

"System.err" for the system error stream.

The syntax of "format" is the same as in FileTargetFactory.
