Member Function Documentation

◆ get_desc()

virtual string EMAN::SmartMaskProcessor::get_desc ( ) const

inlinevirtual

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns: The description of this processor.

Implements EMAN::Processor.

Definition at line 8001 of file processor.h.

                {
                        return "Smart mask processor.";
                }

◆ get_name()

virtual string EMAN::SmartMaskProcessor::get_name ( ) const

inlinevirtual

Get the processor's name.

Each processor is identified by a unique name.

Returns: The processor's name.

Implements EMAN::Processor.

Definition at line 7991 of file processor.h.

                {
                        return NAME;
                }

References NAME.

◆ get_param_types()

virtual TypeDict EMAN::SmartMaskProcessor::get_param_types ( ) const

inlinevirtual

Get processor parameter information in a dictionary.

Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

Returns: A dictionary containing the parameter info.

Reimplemented from EMAN::Processor.

Definition at line 8006 of file processor.h.

                {
                        return new SmartMaskProcessor();
                }

◆ process_inplace()

void SmartMaskProcessor::process_inplace ( EMData * image )

virtual

To process an image in-place.

For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.

Parameters

image The image to be processed.

Implements EMAN::Processor.
