Class lsst::afw::table::OutputFunctorKey¶
-
template<typename
T
>
classOutputFunctorKey
¶ Base class for objects that can extract a value from a record, but are not a true Key themselves.
Objects that inherit from OutputFunctorKey can be passed to BaseRecord::get(), just as true Keys can, but the record will simply pass itself to OutputFunctorKey::get() and return the result.
