Detailed Description

template<typename T>
class lsst.afw.table::PointKey< T >

A FunctorKey used to get or set a geom::Point from an (x,y) pair of int or double Keys.

Definition at line 48 of file aggregates.h.

Constructor & Destructor Documentation

template<typename T>

lsst.afw.table::PointKey< T >::PointKey ( )

inline

Default constructor; instance will not be usable unless subsequently assigned to.

Definition at line 68 of file aggregates.h.

: _x(), _y() {}

template<typename T>

lsst.afw.table::PointKey< T >::PointKey ( Key< T > const &  x, Key< T > const &  y  )

inline

Construct from a pair of Keys.

Definition at line 71 of file aggregates.h.

: _x(x), _y(y) {}

template<typename T>

lsst.afw.table::PointKey< T >::PointKey ( Key< Point< T > > const &  other )

inlineexplicit

Construct from a compound Key<Point>

Key<Point> is now deprecated in favor of PointKey; this constructor is intended to aid in the transition.

Definition at line 79 of file aggregates.h.

: _x(other.getX()), _y(other.getY()) {}

template<typename T>

lsst.afw.table::PointKey< T >::PointKey ( SubSchema const &  s )

inline

Construct from a subschema, assuming x and y subfields.

If a schema has "a_x" and "a_y" fields, this constructor allows you to construct a PointKey via:

*  PointKey<T> k(schema["a"]);
*  

Definition at line 90 of file aggregates.h.

: _x(s["x"]), _y(s["y"]) {}

Member Function Documentation

template<typename T>

static PointKey lsst.afw.table::PointKey< T >::addFields ( Schema &  schema, std::string const &  name, std::string const &  doc, std::string const &  unit  )

static

Add a pair of _x, _y fields to a Schema, and return a PointKey that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_x", "_y", will be appended to this to form the full field names.
[in]	doc	String used as the documentation for the fields.
[in]	unit	String used as the unit for all fields.

template<typename T>

virtual geom::Point<T,2> lsst.afw.table::PointKey< T >::get ( BaseRecord const &  record ) const

virtual

Get a Point from the given record.

Implements lsst.afw.table::OutputFunctorKey< lsst::afw::geom::Point< T, 2 > >.

template<typename T>

Key<T> lsst.afw.table::PointKey< T >::getX ( ) const

inline

Return the underlying x Key.

Definition at line 108 of file aggregates.h.

{ return _x; }

template<typename T>

Key<T> lsst.afw.table::PointKey< T >::getY ( ) const

inline

Return the underlying y Key.

Definition at line 111 of file aggregates.h.

{ return _y; }

template<typename T>

bool lsst.afw.table::PointKey< T >::isValid ( ) const

inline

Return True if both the x and y Keys are valid.

Definition at line 105 of file aggregates.h.

{ return _x.isValid() && _y.isValid(); }

template<typename T>

bool lsst.afw.table::PointKey< T >::operator!= ( PointKey< T > const &  other ) const

inline

Compare the FunctorKey for equality with another, using the underlying x and y Keys.

Definition at line 101 of file aggregates.h.

{ return !(*this == other); }

template<typename T>

bool lsst.afw.table::PointKey< T >::operator== ( PointKey< T > const &  other ) const

inline

Compare the FunctorKey for equality with another, using the underlying x and y Keys.

Definition at line 100 of file aggregates.h.

{ return _x == other._x && _y == other._y; }

template<typename T>

virtual void lsst.afw.table::PointKey< T >::set ( BaseRecord &  record, geom::Point< T, 2 > const &  value  ) const

virtual

Set a Point in the given record.

Implements lsst.afw.table::InputFunctorKey< lsst::afw::geom::Point< T, 2 > >.
