Class: javax.management.monitor.StringMonitor
- public class StringMonitor
- extends Monitor
- implements StringMonitorMBean
Defines a monitor MBean designed to observe the values of a string
attribute.
A string monitor sends notifications as follows:
- if the attribute value matches the string to compare value,
a match notification is sent.
The notify match flag must be set to
true.
Subsequent matchings of the string to compare values do not cause further notifications unless the attribute value differs from the string to compare value. - if the attribute value differs from the string to compare value,
a differ notification is sent.
The notify differ flag must be set to
true.
Subsequent differences from the string to compare value do not cause further notifications unless the attribute value matches the string to compare value.
