◆ Point3Key() [1/5]

template<typename T >

◆ 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"]);

static

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

Parameters
[in,out]schemaSchema to add fields to.
[in]nameName prefix for all fields; "_x", "_y", "_z" 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 all fields.
