Detailed Description

Class that returns a pointer to the writer matching the given input filename.

Author

Marco Vignati

the GetWriter methods ask to the QGeneralFactory for all the QGlobalWriter registered
then return a pointer to the writer matching the extension of the given input filename.
If such a writer has previously been created it just returns a reference to it, otherwise
this class will take care of creating the right QGlobalWriter and try to open the new input file.
