Constructor & Destructor Documentation

QuadrupoleKey() [1/5]

lsst::afw::table::QuadrupoleKey::QuadrupoleKey ( )

inlinenoexcept

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

Definition at line 386 of file aggregates.h.

: _ixx(), _iyy(), _ixy() {}

QuadrupoleKey() [2/5]

lsst::afw::table::QuadrupoleKey::QuadrupoleKey ( Key< double > const & ixx, Key< double > const & iyy, Key< double > const & ixy )

inlinenoexcept

Construct from individual Keys.

Definition at line 389 of file aggregates.h.

            : _ixx(ixx), _iyy(iyy), _ixy(ixy) {}

QuadrupoleKey() [3/5]

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

inline

Construct from a subschema with appropriate subfields.

If the schema has "a_xx", "a_yy" and "a_xy" fields this constructor enables you to construct a QuadrupoleKey via:

QuadrupoleKey k(schema["a"], coordType);

Definition at line 400 of file aggregates.h.

: _ixx(s["xx"]), _iyy(s["yy"]), _ixy(s["xy"]) {}

Member Function Documentation

addFields()

QuadrupoleKey lsst::afw::table::QuadrupoleKey::addFields ( Schema & schema, std::string const & name, std::string const & doc, CoordinateType coordType = CoordinateType::PIXEL )

static

Add a set of quadrupole subfields to a schema and return a QuadrupoleKey that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; ("_xx", "_yy", "_xy") will be appended to this to form the full field names. In celestial coordinates, we use "x" as a synonym for "RA" and "y" for "dec".
[in]	doc	String used as the documentation for the fields.
[in]	coordType	Type of coordinates in use (PIXEL or CELESTIAL).
