Member Function Documentation

virtual string EMAN::TestImageScurve::get_desc ( ) const [inline, virtual]

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 6624 of file processor.h.

                {
                        return "Replace a source image with a lumpy S-curve used for alignment testing";
                }
virtual string EMAN::TestImageScurve::get_name ( ) const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

Definition at line 6619 of file processor.h.

References NAME.

                {
                        return NAME;
                }
virtual TypeDict EMAN::TestImageScurve::get_param_types ( ) const [inline, virtual]

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.

                {
                        return new TestImageScurve();
                }
void TestImageScurve::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:
imageThe image to be processed.
