Detailed Description

template<typename Box>
class lsst::afw::table::BoxKey< Box >

A FunctorKey used to get or set a lsst::geom::Box2I or Box2D from a (min, max) pair of PointKeys.

The Box2IKey and Box2DKey typedefs should be preferred to using the template name directly.

Constructor & Destructor Documentation

◆ BoxKey() [1/5]

template<typename Box >
lsst::afw::table::BoxKey< Box >::BoxKey ( )
defaultnoexcept

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

◆ BoxKey() [2/5]

template<typename Box >
lsst::afw::table::BoxKey< Box >::BoxKey ( PointKey< Element > const &  min,
PointKey< Element > const &  max 
)
inlinenoexcept

Construct from a pair of PointKeys.

Definition at line 151 of file aggregates.h.

151 : _min(min), _max(max) {}
int min
int max

◆ BoxKey() [3/5]

template<typename Box >
lsst::afw::table::BoxKey< Box >::BoxKey ( SubSchema const &  s)
inline

Construct from a subschema, assuming _min_x, _max_x, _min_y, _max_y subfields.

If a schema has "a_min_x" and "a_min_x" (etc) fields, this constructor allows you to construct a BoxKey via:

BoxKey<Box> k(schema["a"]);

Definition at line 161 of file aggregates.h.

161 : _min(s["min"]), _max(s["max"]) {}

◆ BoxKey() [4/5]

template<typename Box >
lsst::afw::table::BoxKey< Box >::BoxKey ( BoxKey< Box > const &  )
defaultnoexcept

◆ BoxKey() [5/5]

template<typename Box >
lsst::afw::table::BoxKey< Box >::BoxKey ( BoxKey< Box > &&  )
defaultnoexcept

◆ ~BoxKey()

template<typename Box >
lsst::afw::table::BoxKey< Box >::~BoxKey ( )

Member Function Documentation

◆ addFields()

template<typename Box >
BoxKey< Box > lsst::afw::table::BoxKey< Box >::addFields ( Schema schema,
std::string const &  name,
std::string const &  doc,
std::string const &  unit 
)
static

Add _min_x, _min_y, _max_x, _max_y fields to a Schema, and return a BoxKey that points to them.

Parameters
[in,out]schemaSchema to add fields to.
[in]nameName prefix for all fields; suffixes above will be appended to this to form the full field names. For example, if name == "b", the fields added will be "b_min_x", "b_min_y", "b_max_x", and "b_max_y".
[in]docString used as the documentation for the fields.
[in]unitString used as the unit for all fields.
