[Insight-users] Is there a member fuction SetFileName funtion of "itk::ImageFileReader< InputImageType > ::Pointer"?

[psd]

I am a beginer of Itk. I notice the flowing codes in a DicomRead example:
 typedef itk::ImageFileReader< InputImageType > ReaderType;
    ReaderType::Pointer reader = ReaderType::New();
  reader->SetFileName( argv[1] );
 
Yet, I go through the http://www.itk.org/Doxygen/html/classitk_1_1ImageFileReader.html
documents and can not find a membership named "SetFileName", who can give a help?
 
Thanks
