Detailed Description

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

A FunctorKey used to get or set a ndarray::Array from a sequence of scalar Keys.

ArrayKey operates on the convention that arrays are defined by a set of contiguous scalar fields (i.e. added to the Schema in order, with no interruption) of the same type, with a common field name prefix and "_0", "_1" etc. suffixes.

Constructor & Destructor Documentation

template<typename T>

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

inline

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

Definition at line 86 of file arrays.h.

86 : _begin() {}

lsst.afw.table::ArrayKey::_begin

Key< T > _begin

Definition: arrays.h:148

template<typename T>

lsst.afw.table::ArrayKey< T >::ArrayKey ( std::vector< Key< T > > const & keys )

explicit

Construct from a vector of scalar Keys.

template<typename T>

lsst.afw.table::ArrayKey< T >::ArrayKey ( Key< Array< T > > const & other )

explicit

Construct from a compound Key< Array<T> >

Key< Array<T> > is now deprecated in favor of ArrayKey; this factory function is intended to aid in the transition.

template<typename T>

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

Construct from a subschema, assuming *_0, *_1, *_2, etc. subfields.

If a schema has "a_0", "a_1", and "a_2" fields, this constructor allows you to construct a 3-element ArrayKey via:

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

Member Function Documentation

template<typename T>

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

static

Add an array of fields to a Schema, and return an ArrayKey that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_0", "_1", etc. will be appended to this to form the full field names.
[in]	doc	String used as the documentation for the fields. Should include a single boost::format template string, which will be substituted with the appropriate element from the docData array to form the full documentation string.
[in]	unit	String used as the unit for all fields.
[in]	docData	Vector of values substituted into the doc fields. The length of the vector determines the number of fields added.
