Detailed Description

template<typename T>
class lsst::afw::cameraGeom::DetectorCollectionBase< T >

An abstract base class for collections of Detectors and specific subclasses thereof.

Template Parameters

T	Element type; either Detector or a subclass thereof.

This class provides the common interface and implementation for DetectorCollection (which holds true Detector instances) and Camera::Builder (which holds Detector::InCameraBuilder instances). It is not intended to define an interface independent of those classes.

Member Function Documentation

add()

template<typename T >

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

protected

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.
