Constructor & Destructor Documentation

EllipseKey() [1/5]

lsst::afw::table::EllipseKey::EllipseKey ( )

inlinenoexcept

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

Definition at line 376 of file aggregates.h.

: _qKey(), _pKey() {}

EllipseKey() [2/5]

lsst::afw::table::EllipseKey::EllipseKey ( QuadrupoleKey const &  qKey, PointKey< double > const &  pKey  )

inlinenoexcept

Construct from individual Keys.

Definition at line 379 of file aggregates.h.

: _qKey(qKey), _pKey(pKey) {}

EllipseKey() [3/5]

lsst::afw::table::EllipseKey::EllipseKey ( SubSchema const &  s )

inline

Construct from a subschema, assuming (xx, yy, xy, x, y) subfields.

If a schema has "a_xx", "a_yy", "a_xy", "a_x", and "a_y" fields, this constructor allows you to construct an EllipseKey via:

EllipseKey k(schema["a"]);

Definition at line 389 of file aggregates.h.

: _qKey(s), _pKey(s) {}

Member Function Documentation

addFields()

EllipseKey lsst::afw::table::EllipseKey::addFields ( Schema &  schema, std::string const &  name, std::string const &  doc, std::string const &  unit  )

static

Add a set of _xx, _yy, _xy, _x, _y fields to a Schema, and return an EllipseKey that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_xx", "_yy", "_xy", "_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 x and y fields; "<unit>^2" will be used for xx, yy, and xy fields.
