/**
|
|
* @file
|
|
* Editor action classes. Some important points:
|
|
* - This is a polymorphic hierarchy of classes, so actions are usually passed around
|
|
* as editor_action pointers
|
|
* - The pointers can, in general, be null. Always check for null before doing anything.
|
|
* The helper functions perform_ that take a pointer do that.
|
|
* - The perform() functions can throw when an error occurs. Use smart pointers if you
|
|
* need to ensure the pointer is deleted.
