Validity. A trigger is set as invalid when the specified manager UI, owner process or trigger handling process( for start-up trigger ) is removed from the system. The process can be removed for example when it resides in removable media( like MMC ), and that media is removed from the terminal. An invalid trigger is not included in the trigger supervision process. When the removable media with the specified process is attached back to the terminal, the trigger is set as valid and included in the trigger supervision process, provided that the trigger is not disabled. When a trigger has been invalid longer than the system clean-up time, the trigger is removed from the system. The system clean-up time is defined by the system and can't be accessed by client application. Note, if a trigger's owner process, manager UI or trigger handling process( for start-up trigger ) is uninstalled from the system, the trigger will be removed by Location Triggering Server.
