backupSettings
void backupSettings()Creates a backup of the current settings state that can be restored later on. The settings are backed up in a stack, so multiple calls to this method put different copies of the settings on the stack in a LIFO fashion.
This method, together with
restoreSettings()
, are useful to back up and restore the settings at the beginning and end of your scripts, respectively, and ensure that the user settings are left unmodified after your script ends. -
restoreSettings
boolean restoreSettings()Takes the settings object at the top of the settings stack and makes it effective.
This method, together with
backupSettings()
, are useful to back up and restore the settings at the beginning and end of your scripts, respectively, and ensure that the user settings are left unmodified after your script ends.WARN: This function applies all settings immediately, and the user interface may be re-initialized. Be aware that the UI may be set to its default state after this call.
- Returns:
- True if the stack was not empty and the settings were restored successfully. False otherwise.
