javax.management.monitor.Monitor
   javax.management.monitor.StringMonitor

StringMonitor
public class StringMonitor extends Monitor implements StringMonitorMBean(Code)
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 MonitorNotification.STRING_TO_COMPARE_VALUE_MATCHED 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 MonitorNotification.STRING_TO_COMPARE_VALUE_DIFFERED 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.

Inner Class :class StringMonitorThread implements Runnable

Constructor Detail
StringMonitor
public StringMonitor()(Code)
Default Constructor.




Method Detail
getDerivedGauge
public String getDerivedGauge()(Code)
This method gets the value of the derived gauge. The derived gauge is either the exact value of the observed attribute , or the difference between the two consecutive observed values of the attribute. An instance of java.lang.String giving the value of the derived gauge.



getDerivedGaugeTimeStamp
public long getDerivedGaugeTimeStamp()(Code)
This method gets the value of the derived gauge time stamp.The derived gauge time stamp is the value(in the nearest miliseconds) when the notification was triggered. long value representing the time the notification was triggered.



getNotificationInfo
public MBeanNotificationInfo[] getNotificationInfo()(Code)



getNotifyDiffer
public boolean getNotifyDiffer()(Code)
This method sets the differing notification's on/off switch value. The differing notification's on/off switch value.



getNotifyMatch
public boolean getNotifyMatch()(Code)
This method gets the matching notification's on/off switch value. The matching notification's on/off switch value.



getStringToCompare
public String getStringToCompare()(Code)
This method gets the string to compare with the observed attribute. the String to be compared.



preRegister
public ObjectName preRegister(MBeanServer server, ObjectName name) throws Exception(Code)
Overriding the preRegister() of MBeanRegistration interface to store the ObjectName locally.



setNotifyDiffer
public void setNotifyDiffer(boolean value)(Code)
This method sets the differing notification's on/off switch value.
Parameters:
  value - - The differing notification's on/off switch value.



setNotifyMatch
public void setNotifyMatch(boolean value)(Code)
This method sets the matching notification's on/off switch value.
Parameters:
  value - - The matching notification's on/off switch value.



setStringToCompare
public void setStringToCompare(String value) throws IllegalArgumentException(Code)
This method sets the string to compare with the observed attribute.
Parameters:
  The - String Value to be compared.
exception:
  java.lang.IllegalArgumentException - - The specified string tocompare is null.



start
public void start()(Code)
