Member Function Documentation

get_desc()

string EMAN::ValuePowProcessor::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 2466 of file processor.h.

                {
                        return "f(x) = x ^ pow;";
                }

get_name()

string EMAN::ValuePowProcessor::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 2444 of file processor.h.

                {
                        return NAME;
                }

References NAME.

get_param_types()

TypeDict EMAN::ValuePowProcessor::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.
