Functions

template<typename Container, typename... Ts> HPX_CXX_CORE_EXPORT void save_checkpoint_data (Container &data, Ts &&... ts)

save_checkpoint_data

Save_checkpoint_data takes any number of objects which a user may wish to store in the given container.

Template Parameters

  • Container – Container used to store the check-pointed data.

  • Ts – Types of variables to checkpoint

Parameters

  • data – Container instance used to store the checkpoint data

  • ts – Variable instances to be inserted into the checkpoint.

template<typename... Ts> HPX_CXX_CORE_EXPORT std::size_t prepare_checkpoint_data (Ts const &... ts)

prepare_checkpoint_data

prepare_checkpoint_data takes any number of objects which a user may wish to store in a subsequent save_checkpoint_data operation. The function will return the number of bytes necessary to store the data that will be produced.

Template Parameters

Ts – Types of variables to checkpoint

Parameters

ts – Variable instances to be inserted into the checkpoint.

template<typename Container, typename... Ts> HPX_CXX_CORE_EXPORT void restore_checkpoint_data (Container const &cont, Ts &... ts)

restore_checkpoint_data

restore_checkpoint_data takes any number of objects which a user may wish to restore from the given container. The sequence of objects has to correspond to the sequence of objects for the corresponding call to save_checkpoint_data that had used the given container instance.

Template Parameters

  • Container – Container used to restore the check-pointed data.

  • Ts – Types of variables to restore

Parameters

  • cont – Container instance used to restore the checkpoint data

  • ts – Variable instances to be restored from the container
