YQPkgWarningRangeNotifier Class Reference
#include <YQPkgDiskUsageList.h>
List of all members.
Detailed Description
Helper class to manage warnings that are to be issued when a value enters a predefined range, but repeated only when that value leaves a ( wider ) "proximity" range and then re-enters the ( narrower ) "inner" range.
Example: Disk space usage:
70% 75% 80% [proximity range start] 85% 90% [inner range start] 95% 100%
A warning is to be posted when there is only 90% disk space left. After the warning is displayed, there shall be no more warning until disk usage decreases below 80% ( the proximity range ) and then later increases again to 90%.
The net effect of all that is to avoid posting the warning over and over again while the value changes back and forth around the boundary of the ( inner ) warning range.
