Detailed Description

Class that maps ShapeletFunction objects to fields in afw::table objects.

A ShapeletFunctionKey manages a set of fields with a common prefix and the following suffixes:

• "x", "y", "xx", "yy", "xy": ellipse
• "0", "1", "2", ...: coefficients.

As with all FunctorKeys, a ShapeletFunctorKey can be used to directly get or set objects on an afw::table::BaseRecord, just as with a true Key.

Constructor & Destructor Documentation

ShapeletFunctionKey() [1/3]

lsst::shapelet::ShapeletFunctionKey::ShapeletFunctionKey ( )

inline

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

Definition at line 74 of file FunctorKeys.h.

: _ellipseKey(), _coefficientsKey(), _order(-1), _basisType(HERMITE) {}

ShapeletFunctionKey() [2/3]

lsst::shapelet::ShapeletFunctionKey::ShapeletFunctionKey ( afw::table::EllipseKey const & ellipse, afw::table::ArrayKey< double > const & coefficients, BasisTypeEnum basisType = HERMITE )

inline

Construct from individual Keys/FunctorKeys.

Definition at line 77 of file FunctorKeys.h.

      :
        _ellipseKey(ellipse),
        _coefficientsKey(coefficients),
        _order(computeOrder(coefficients.getSize())),
        _basisType(basisType)
    {}

ShapeletFunctionKey() [3/3]

lsst::shapelet::ShapeletFunctionKey::ShapeletFunctionKey ( afw::table::SubSchema const & s, BasisTypeEnum basisType = HERMITE )

inline

Construct from a subschema, assuming the necesary subfields.

If a schema has e.g. "a_xx", "a_0", etc. fields, this constructor allows you to construct a ShapeletFunctionKey via:

ShapeletFunctionKey k(schema["a"]);

Definition at line 97 of file FunctorKeys.h.

                                                                                      :
        _ellipseKey(s), _coefficientsKey(s),
        _order(computeOrder(_coefficientsKey.getSize())),
        _basisType(basisType)
    {}

Member Function Documentation

addFields()

static ShapeletFunctionKey lsst::shapelet::ShapeletFunctionKey::addFields ( afw::table::Schema & schema, std::string const & name, std::string const & doc, std::string const & ellipseUnit, std::string const & coeffUnit, int order, BasisTypeEnum basisType = HERMITE )

static

Add the necessary fields for saving a ShapeletFunction to a Schema.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields.
[in]	doc	String used as the documentation for the fields.
[in]	ellipseUnit	String used as the unit for the ellipse ("<ellipseUnit>^2" will be used for the Quadrupole moments).
[in]	coeffUnit	String used as the unit for the coefficient vector
[in]	order	Order of the ShapeletFunction to be saved.
[in]	basisType	Type of shapelet basis (HERMITE or LAGUERRE) to be saved.

This method provides only basic exception safety - the schema may be (partially) modified even if an exception is thrown.

{ return _coefficientsKey; }

getEllipse()

afw::table::EllipseKey const & lsst::shapelet::ShapeletFunctionKey::getEllipse ( ) const
