public class StringMonitor extends Monitor implements StringMonitorMBean
A string monitor sends notifications as follows:
match notification
is sent. The notify match flag must be set to true
. differ notification
is sent. The notify differ flag must be set to true
. alreadyNotified, alreadyNotifieds, capacityIncrement, dbgTag, elementCount, OBSERVED_ATTRIBUTE_ERROR_NOTIFIED, OBSERVED_ATTRIBUTE_TYPE_ERROR_NOTIFIED, OBSERVED_OBJECT_ERROR_NOTIFIED, RESET_FLAGS_ALREADY_NOTIFIED, RUNTIME_ERROR_NOTIFIED, server
