Member Function Documentation

get_desc()

virtual string EMAN::ACFCenterProcessor::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 7177 of file processor.h.

                {
                        return "Center image using self-convolution.";
                }

get_name()

virtual string EMAN::ACFCenterProcessor::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 7167 of file processor.h.

                {
                        return NAME;
                }

References NAME.

get_param_types()

virtual TypeDict EMAN::ACFCenterProcessor::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 7182 of file processor.h.

                {
                        TypeDict d;
                        return d;
                }

NEW()

static Processor * EMAN::ACFCenterProcessor::NEW ( )

inlinestatic

Definition at line 7172 of file processor.h.

                {
                        return new ACFCenterProcessor();
                }

process_inplace()

void ACFCenterProcessor::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.

Definition at line 7535 of file processor.cpp.
