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.

376 : _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.

379 : _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"]);

◆ 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]schemaSchema to add fields to.
[in]nameName prefix for all fields; "_xx", "_yy", "_xy", "_x" ,"_y", will be appended to this to form the full field names.
[in]docString used as the documentation for the fields.
[in]unitString used as the unit for x and y fields; "<unit>^2" will be used for xx, yy, and xy fields.
