Member Function Documentation

add()

void lsst::afw::cameraGeom::DetectorCollectionBase< Detector const >::add ( std::shared_ptr< Detector const >  detector )

protectedinherited

Add a detector to the collection.

Parameters

[in]

detector

New detector to add to the collection.

Exceptions

pex::exceptions::RuntimeError

Thrown if the ID and/or name conflict with those of detectors already in the collection.

Exception Safety

Strong for pex::exceptions::RuntimeError, weak (collection is made empty) otherwise.

Reimplemented from lsst::afw::table::io::Persistable.
