Class lsst::afw::table::ConstReferenceFunctorKey¶
-
template<typename
T
>
classConstReferenceFunctorKey
¶ 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.
