Class lsst::afw::table::ConstReferenceFunctorKey

template<typename T>
class ConstReferenceFunctorKey

Base class for objects that can return a const reference to part of a record, but are not a true Key

Objects that inherit from ConstReferenceFunctorKey can be passed to BaseRecord::operator[], just as true Keys can, but the record will simply pass itself to ReferenceFunctorKey::getConstReference().

Note

We’d combine this with the ReferenceFunctorKey interface if it weren’t for the fact that we can’t pass multiple template arguments to a Swig macro if either contains commas, and we’d need that to wrap a combined interface base class.
