◆ addPersistableMethods()

template<typename Class , typename... Args>
void lsst::afw::table::io::python::addPersistableMethods ( pybind11::class_< Class, Args... > & cls)

Add table::io::Persistable and PersistableFacade methods to the pybind11 wrapper for a class.

This allows your class to be used without importing lsst.afw.table in Python.

Use as follows:

  • When declaring the pybind11 class that wraps your Class in afw, do not list table::io::PersistableFacade<Class> and table::io::Persistable as base classes unless you have to, and in that case be prepared for possible trouble.
  • Call this function to wrap the methods that make your object persistable.
