Detailed Description

template<typename T = KernelPsf, typename K = afw::math::Kernel>
class lsst::meas::algorithms::KernelPsfFactory< T, K >

A PersistableFactory for KernelPsf and its subclasses.

If a KernelPsf subclass has no data members other than its kernel, table persistence for it can be implemented simply by reimplementing getPersistenceName() and registering a specialization of KernelPsfFactory.

Template Parameters

T	KernelPsf subclass the factory will construct.
K	Kernel subclass the Psf constructor requires.

lookup()

PersistableFactory const & lsst::afw::table::io::PersistableFactory::lookup ( std::string const &  name, std::string const &  module = ""  )

staticinherited

Return the factory that has been registered with the given name.

If the lookup fails and module is not an empty string, we will attempt to import a Python module with that name (this will only work when the C++ is being called from Python) and try again.
