Detailed Description

template<typename Derived, typename T, int N>
class lsst::afw::geom::CoordinateBase< Derived, T, N >

A CRTP base class for coordinate objects.

CoordinateBase has partial specializations for 2 and 3 dimensions so its subclasses don't have to.

Constructor & Destructor Documentation

template<typename Derived, typename T, int N>

lsst::afw::geom::CoordinateBase< Derived, T, N >::CoordinateBase ( T  val = static_cast<T>(0) )

inlineexplicitprotected

Initialize all elements to a scalar.

A public constructor with the same signature is expected for subclasses.

Definition at line 78 of file CoordinateBase.h.

: _vector(EigenVector::Constant(val)) {}

template<typename Derived, typename T, int N>

template<typename Vector >

lsst::afw::geom::CoordinateBase< Derived, T, N >::CoordinateBase ( Eigen::MatrixBase< Vector > const &  vector )

inlineexplicitprotected

Initialize all elements from an N-d Eigen vector.

A public constructor with the same signature is expected for subclasses.

EigenVector const& lsst::afw::geom::CoordinateBase< Derived, T, N >::asEigen ( ) const

inline

Return a fixed-size Eigen representation of the coordinate object.

The fact that this returns by const reference rather than by value should not be considered part of the API; this is merely an optimization enabled by the implementation.
