# Allows controlling whether notifications are sent out for created journals.
|
|
# After the block is executed, the setting is returned to its original state which is true by default.
|
|
# In case the method is called multiple times within itself, the first setting prevails.
|
|
# This allows to control the setting globally without having to pass the setting down the call stack in
|
|
# order to ensure all subsequent code follows the provided setting.
