Get the descrition of this specific processor. This function must be overwritten by a subclass.
Reimplemented from EMAN::CircularMaskProcessor. Definition at line 2588 of file processor.h. 02589 { 02590 return "a gaussian falloff to zero, radius is the 1/e of the width. If inner_radius>0, then \ 02591 outer radius specifies width of Gaussian starting at inner_radius rather than total radius."; 02592 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 2563 of file processor.h. References NAME. 02564 { 02565 return NAME; 02566 }
