Functions

template<typename T>
void declarePersistableFacade(pybind11::module &module, std::string const &suffix)

Wraps an instantiation of PersistableFacade.

Pybind11 shall assume that PersistableFacade is managed using std::shared_ptr, as this is required for compatibility with existing subclasses of PersistableFacade. This means that wrapping will only work if new classes also use std::shared_ptr as their holder type.

Template Parameters
Parameters

  • module: The pybind11 module that shall contain PersistableFacade<T>

  • suffix: A string to disambiguate this class from other PersistableFacades. The Python name of this class shall be PersistableFacade<suffix>.

template<typename Class, typename ...Args>
void addPersistableMethods(pybind11::class_<Class, Args...> &cls)

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

Use this instead of declarePersistableFacade to avoid circular import issues in Python; it allows your class to be used without importing lsst.afw.table.

Use as follows:

  • When declaring the pybind11 class that wraps your Class do not list table::io::PersistableFacade<Class> and table::io::Persistable as subclasses.

  • Call this function to wrap the methods that make your object persistable.
