Generic Function

Summary

Called before an interface is destroyed during session saving.

Signature

interface-preserve-state interface

Arguments

interface

An interface.

Description

The generic function interface-preserve-state is called by hcl:save-current-session just before it destroys an interface, on the interface process. You can specialize this for your own interface classes. Your methods should not interact with the user or other external sources, and should not interact with other processes, because it is called after hcl:save-current-session already started to destroy interfaces.

The return value is not used.

The default method does nothing.
