Package WebGUI::Session::Output

|
|
|
|
This class provides a handler for returning output. Through this we can apply filters (like macros), and simple page caching mechanisms.

=head2 setHandle ( handle )
|
|
|

Sets a handle to print the content to. If we're running in command line mode, WebGUI assumes we're printing to standard out, and if we were called through mod_perl it assumes we're printing to that.

=head3 handle
|
|
|
|
An open FILE handle that WebGUI can print to.
