Class lsst::afw::cameraGeom::TransformMap

class TransformMap : public lsst::afw::table::io::PersistableFacade<TransformMap>, public lsst::afw::table::io::Persistable

A registry of 2-dimensional coordinate transforms for a specific camera.

Represents the interrelationships between camera coordinate systems for a particular camera. It can be seen as a mapping between a pair of CameraSys and a Transform between them (though it does not conform to either the C++ map or Python dictionary APIs).

TransformMap supports:

• Transforming between any two supported CameraSys using the transform methods.

• Retrieving a transform between any two supported CameraSys using getTransform.

• Iteration over supported CameraSys using begin and end in C++ and standard Python iteration in Python.

TransformMap is immutable and must always be held by shared_ptr; this is enforced by making all non-deleted constructors private, and instead providing static make member functions for construction (in Python, these are exposed as regular constructors).

Unless otherwise specified, all methods guarantee only basic exception safety.
