StringStatisticMonitor

• java.lang.Object
  • StatisticMonitor

Fields Summary
protected static final Logger	_logger
private String	stringToCompare String to compare with the observed attribute. The default value is an empty character sequence.
private boolean	notifyMatch Flag indicating if the string statistic monitor notifies when matching the string to compare. The default value is set to false.
private boolean	notifyDiffer Flag indicating if the string statistic monitor notifies when differing from the string to compare. The default value is set to false.
private int[]	status This attribute is used to handle the matching/differing mechanism. Each element in this array corresponds to an observed object in the list.
private static final String[]	types
private static final MBeanNotificationInfo[]	notifsInfo
private static final int	MATCHING
private static final int	DIFFERING
private static final int	MATCHING_OR_DIFFERING

public synchronized java.lang.String	getDerivedGauge(javax.management.ObjectName object) Gets the derived gauge of the specified object, if this object is contained in the set of observed MBeans, or null otherwise. param object the name of the MBean whose derived gauge is required. return The derived gauge of the specified object. since.unbundled JMX 1.2 return (String) super.getDerivedGauge(object);
public synchronized java.lang.String	getDerivedGauge() Returns the derived gauge of the first object in the set of observed MBeans. return The derived gauge. deprecated As of JMX 1.2, replaced by {@link #getDerivedGauge(ObjectName)} return (String) derivedGauge[0];
public synchronized long	getDerivedGaugeTimeStamp(javax.management.ObjectName object) Gets the derived gauge timestamp of the specified object, if this object is contained in the set of observed MBeans, or null otherwise. param object the name of the object whose derived gauge timestamp is to be returned. return The derived gauge timestamp of the specified object. since.unbundled JMX 1.2 return super.getDerivedGaugeTimeStamp(object);
public synchronized long	getDerivedGaugeTimeStamp() Gets the derived gauge timestamp of the first object in the set of observed MBeans. return The derived gauge timestamp. deprecated As of JMX 1.2, replaced by {@link #getDerivedGaugeTimeStamp(ObjectName)} return derivedGaugeTimestamp[0];
public javax.management.MBeanNotificationInfo[]	getNotificationInfo() Returns a NotificationInfo object containing the name of the Java class of the notification and the notification types sent by the string statistic monitor. return notifsInfo.clone();
public synchronized boolean	getNotifyDiffer() Gets the differing notification's on/off switch value common to all observed MBeans. return true if the string statistic monitor notifies when differing from the string to compare, false otherwise. see #setNotifyDiffer return notifyDiffer;
public synchronized boolean	getNotifyMatch() Gets the matching notification's on/off switch value common to all observed MBeans. return true if the string statistic monitor notifies when matching the string to compare, false otherwise. see #setNotifyMatch return notifyMatch;
public synchronized java.lang.String	getStringToCompare() Gets the string to compare with the observed attribute common to all observed MBeans. return The string value. see #setStringToCompare return stringToCompare;
synchronized void	insertSpecificElementAt(int index) This method is called when adding a new observed object in the vector. It updates all the string specific arrays. param index The index of the observed object. // Update status array. // if (elementCount >= status.length) { status = expandArray(status); } status[index] = MATCHING_OR_DIFFERING;
boolean	isComparableTypeValid(javax.management.ObjectName object, java.lang.String attribute, java.lang.Comparable value) Check that the type of the supplied observed attribute value is one of the value types supported by this monitor. // Check that the observed attribute is of type "String". // if (value instanceof String) { return true; } return false;

synchronized void	removeSpecificElementAt(int index) This method is called when removing an observed object from the vector. It updates all the string specific arrays. param index The index of the observed object. // Update status array. // removeElementAt(status, index);
public synchronized void	setNotifyDiffer(boolean value) Sets the differing notification's on/off switch value common to all observed MBeans. param value The differing notification's on/off switch value. see #getNotifyDiffer notifyDiffer = value;
public synchronized void	setNotifyMatch(boolean value) Sets the matching notification's on/off switch value common to all observed MBeans. param value The matching notification's on/off switch value. see #getNotifyMatch notifyMatch = value;
public synchronized void	setStringToCompare(java.lang.String value) Sets the string to compare with the observed attribute common to all observed MBeans. param value The string value. exception IllegalArgumentException The specified string to compare is null. see #getStringToCompare if (value == null) { throw new IllegalArgumentException("Null string to compare"); } stringToCompare = value; // Reset values. // for (int i = 0; i < elementCount; i++) { status[i] = MATCHING_OR_DIFFERING; }
public synchronized void	start() Starts the string monitor. // Reset values. // for (int i = 0; i < elementCount; i++) { status[i] = MATCHING_OR_DIFFERING; } doStart();
public synchronized void	stop() Stops the string monitor. doStop();
