public class StatisticsService
extends Object

AutoPlay sessions, for example, are flagged as:

ID	event_time	event_type	jiffydos	session_id	disk_id	event_kind	key_table_entry
5	0	START	true	731830e00f8777d8e13eced45522f167	731830e00f8777d8e13eced45522f167	DISK	null

6	100	CHANGE	true	731830e00f8777d8e13eced45522f167	731830e00f8777d8e13eced45522f168	DISK	null
5	150	KEY_TYPED	true	731830e00f8777d8e13eced45522f167	null	KEY	SPACE

8	300	STOP	true	731830e00f8777d8e13eced45522f167	null	END	null

This describes a typical demo using three disks where session id is always the first disk's MD5 and disk_id is the first, second, or third disk's MD5. Event types are:

 START (first disk inserted)
 KEY_TYPED (space-bar was hit)
 CHANGE (second disk inserted)
 KEY_TYPED (space-bar was hit)
 CHANGE (third disk inserted)
 STOP (demo stopped)

getDiskEvent

 boolean jiffyDos,
 Long id)

Retrieves an optional DiskEvent for the specified disk MD5 and jiffyDos flag. Can be used to find the current session ID and when the disk has been inserted.

Parameter:

currentDiskMd5 - the MD5 hash of the disk to match in the query

jiffyDos - a boolean flag indicating whether the fastloader JiffyDos has been used

Gibt zurück:

an Optional containing the matching DiskEvent if found
