See Also:

Constant Field Values

SUBSYSTEM_NAME_KEY

public static final java.lang.String SUBSYSTEM_NAME_KEY

The JMX Object Name property key that identifies the name of the internal subsystem in a Usage MBean whose UsageMBean.NOTIFICATION_SOURCE_KEY property has a value equal to USAGE_NOTIFICATION_TYPE. This key is equal to the string "subsystemName".

Since:

SLEE 1.1

Constructor Detail

SubsystemNotification

public SubsystemNotification(java.lang.String subsystemName)

Create a new SubsystemNotification object that uniquely identifies an internal component or subsystem of the SLEE.

Parameters:

subsystemName - the name of the SLEE internal component or subsystem. Subsystem names may be any vendor-defined string.

Throws:

java.lang.NullPointerException - if subsystemName is null.

Method Detail

getSubsystemName

public java.lang.String getSubsystemName()

Get the name of the internal component or subsystem of the SLEE identified by this notification source.

Returns:

the name of the internal component or subsystem.

getAlarmNotificationType

public java.lang.String getAlarmNotificationType()

Get the JMX notification type of alarm notifications generated in response to a SLEE internal component or subsystem interacting with the Alarm Facility.

Specified by:

getAlarmNotificationType in interface NotificationSource

Returns:

the string defined by ALARM_NOTIFICATION_TYPE.

getTraceNotificationType

public java.lang.String getTraceNotificationType()

Get the JMX notification type of trace notifications generated in response to a SLEE internal component or subsystem interacting with the Trace Facility.

Specified by:

getTraceNotificationType in interface NotificationSource

Returns:

the string defined by TRACE_NOTIFICATION_TYPE.

getUsageNotificationType

public java.lang.String getUsageNotificationType()

Get the JMX notification type of usage notifications generated in response to a SLEE internal component or subsystem interacting with its usage parameters.

Specified by:

getUsageNotificationType in interface NotificationSource

Returns:

the string defined by USAGE_NOTIFICATION_TYPE.

getUsageMBeanProperties

public static java.lang.String getUsageMBeanProperties(java.lang.String subsystemName)

Get a JMX Object Name property string that uniquely identifies the specified SLEE internal component or subsystem, suitable for inclusion in the Object Name of a Usage MBean. This method makes use of the ObjectName.quote(java.lang.String) method to ensure that the name is valid for inclusion as property values in an Object Name.

This method can be used as follows to manually construct a complete Object Name for a Usage MBean:

ObjectName name = new ObjectName(
UsageMBean.BASE_OBJECT_NAME + "," +
UsageMBean.USAGE_PARAMETER_SET_NAME_KEY + "=" + ObjectName.quote(paramSetName) + "," // optional
UsageMBean.NOTIFICATION_SOURCE_KEY + "=" + SubsystemNotification.USAGE_NOTIFICATION_TYPE + "," +
SubsystemNotification.getUsageMBeanProperties(subsystemName)
);

Parameters:

subsystemName - the name of the SLEE internal component or subsystem.

Returns:

an Object Name property string that uniquely identifies the specified internal component or subsystem.

Throws:

java.lang.NullPointerException - if subsystem is null.

getUsageMBeanProperties

public java.lang.String getUsageMBeanProperties()

Get a JMX Object Name property string that uniquely identifies the SLEE internal component or subsystem of this notification source, suitable for inclusion in the Object Name of a Usage MBean.

This method is equivalent to getUsageMBeanProperties(getSubsystemName()).

Returns:

an Object Name property string that uniquely identifies the internal component or subsystem.

equals

public boolean equals(java.lang.Object obj)

Compare this notification source for equality with another object.

Specified by:

equals in interface NotificationSource

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare this with.

Returns:

true if obj is an instance of this class and contains the subsystem name as this, false otherwise.

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Get a hash code value for this notification source.

Specified by:

hashCode in interface NotificationSource

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this notification source.

See Also:

Object.hashCode()

toString

public java.lang.String toString()

Get a string representation for this notification source.

Specified by:

toString in interface NotificationSource

Overrides:

toString in class java.lang.Object

Returns:

a string representation for this notification source.

See Also:

Object.toString()

compareTo

public int compareTo(java.lang.Object obj)

Compare this notification source with the specified object for order. Returns a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object.

If obj is a SubsystemNotification, order is determined by comparing the encapsulated subsystem name. Otherwise, if obj is a NotificationSource, ordering is determined by comparing the class name of this class with the class name of obj.

Specified by:

compareTo in interface java.lang.Comparable

Specified by:

compareTo in interface NotificationSource

Parameters:

obj - the object to compare this with.

Returns:

a negative integer, zero, or a positive integer if this notification source is considered less than, equal to, or greater than the specified object.

Throws:

java.lang.ClassCastException - if obj does not implement the NotificationSource interface.

See Also:

Comparable.compareTo(Object)

Get the class name of this notification source. More efficient than getClass().getName().

Returns:

the class name of this notification source.

compareTo

protected final int compareTo(java.lang.String thisClassName,
                              java.lang.Object that)
