Class Documentation

template<typename T>
class OutputFunctorKey

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.

Subclassed by lsst::afw::table::FunctorKey< T >
