Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 3239 of file processor.h.
|
|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 3230 of file processor.h. References NAME. Referenced by process_inplace(). 03231 { 03232 return NAME; 03233 }
