template<typename T>

lsst::afw::table::Point3Key< T >::Point3Key ( Key< T > const & x, Key< T > const & y, Key< T > const & z )

Construct from a pair of Keys.

Point3Key() [5/5]

template<typename T>

lsst::afw::table::Point3Key< T >::Point3Key ( SubSchema const & s )

inline

Construct from a subschema, assuming x and y subfields.

If a schema has "a_x", "a_y", and "a_z" fields, this constructor allows you to construct a Point3Key via:

Point3Key<T> k(schema["a"]);

Definition at line 160 of file aggregates.h.

: _x(s["x"]), _y(s["y"]), _z(s["z"]) {}

Member Function Documentation

addFields()

template<typename T>

Point3Key< T > lsst::afw::table::Point3Key< T >::addFields ( Schema & schema, std::string const & name, std::string const & doc, std::string const & unit )

static

Add a pair of _x, _y, _z fields to a Schema, and return a Point3Key that points to them.

Parameters

[in,out]	schema	Schema to add fields to.
[in]	name	Name prefix for all fields; "_x", "_y", "_z" will be appended to this to form the full field names.
[in]	doc	String used as the documentation for the fields.
[in]	unit	String used as the unit for all fields.
