/**
 * Data class for trigger's dynamic system information, such as 
 * trigger validity and distance to the latest acquired location.
 * 
 * Client application can get following dynamic information of a trigger
 * after it's created. 
 *
 * -  <B>Validity</B>. 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.
 *
 * -  <B>Distance to the Latest Acquired Location</B>.
