Detailed Description

A 2D coordinate representing the center of a plane figure.

This is a centroid in a 2D coordinate system, generally used for ellipses in this package. Storage is implemented in CentroidData.

Parameters

data	The centroid data

Member Function Documentation

convolve()

void lsst::gauss2d::Centroid::convolve

(

const Centroid &

cen

)

Convolve this with another centroid.

Convolution simply adds the value of the other centroid to this.

Parameters

cen	The centroid to convolve with

Definition at line 69 of file centroid.cc.

                                           {
    this->set_x(this->get_x() + cen.get_x());
    this->set_y(this->get_y() + cen.get_y());
}

get_data()

const CentroidData & lsst::gauss2d::Centroid::get_data

(

)

const

Get this centroid's data.

Definition at line 74 of file centroid.cc.

{ return *_data; }

get_x()

double lsst::gauss2d::Centroid::get_x

(

)

const

Get the x value.

Definition at line 76 of file centroid.cc.

{ return _data->get_x(); }

get_xy()

std::array< double, 2 > lsst::gauss2d::Centroid::get_xy

(

)

const

Get the x and y values.

Definition at line 78 of file centroid.cc.

{ return _data->get_xy(); }

get_y()

double lsst::gauss2d::Centroid::get_y

(

)

const

Get the y value.

Definition at line 80 of file centroid.cc.

{ return _data->get_y(); }

make_convolution()

std::shared_ptr< Centroid > lsst::gauss2d::Centroid::make_convolution

(

const Centroid &

cen

)

const

Return the convolution of this with another centroid.

Convolution simply adds the values of both centroids together

Parameters

cen	The centroid to convolve with

Returns

A new centroid with values set to the convolution.

Definition at line 82 of file centroid.cc.

                                                                            {
    return this->make_convolution_uniq(cen);
}

make_convolution_uniq()

std::unique_ptr< Centroid > lsst::gauss2d::Centroid::make_convolution_uniq

(

const Centroid &

cen

)

const

Same as make_convolution(), but returning a unique_ptr.

Definition at line 85 of file centroid.cc.

                                                                                 {
    // TODO: Replace with cloning derived data
    std::unique_ptr<Centroid> cen_ret = std::make_unique<Centroid>(this->get_x(), this->get_y());
    cen_ret->convolve(cen);
    return cen_ret;
}

};

repr()

std::string lsst::gauss2d::Centroid::repr ( bool name_keywords = false, std::string_view namespace_separator = Object::CC_NAMESPACE_SEPARATOR ) const

overridevirtual

Return a full, callable string representation of this.

Parameters

name_keywords	Whether to prefix arguments with "{name}=", where name is the arg name in the header (as with keyword arguments in Python).
namespace_separator	The string to use to delimit namespaces, i.e. :: in C++ and . in Python.

Returns

A callable string representation of this, which should return an an identical object to this.

Note

The representation with name_keywords=false must be callable in C++. The representation with name_keywords=true should be callable in Python, if there are any bindings.
