TypeDict EMAN::MaskGaussInvProcessor::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::CircularMaskProcessor.

Definition at line 2589 of file processor.h.

References EMAN::EMObject::FLOAT, EMAN::CircularMaskProcessor::get_param_types(), EMAN::EMObject::INT, and EMAN::TypeDict::put().

                {
                        TypeDict d = CircularMaskProcessor::get_param_types();
                        d.put("gauss_width", EMObject::FLOAT, "Used to calculate the constant factor - gauss_width / (ny*ny)" );
                        d.put("ring_width", EMObject::INT, "The width of the mask ring.");

                }

string EMAN::MaskGaussInvProcessor::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.
