Field Detail

active

protected Set active

The set of currently active Java Virtual Machines for the MonitoredHost. The set contains an Integer object holding the lvmid for each active Java Virtual Machine on the MonitoredHost. This Set will only contain Integer objects.

started

protected Set started

The set of Java Virtual Machines started on MonitoredHost since the previous event. The set contains an Integer object holding the lvmid for each Java Virtual Machine started on the MonitoredHost. This Set will only contain Integer objects.

terminated

protected Set terminated

The set of Java Virtual Machines terminated on MonitoredHost since the previous event. The set contains an Integer object holding the lvmid for each Java Virtual Machine started on the MonitoredHost. This Set will only contain Integer objects.

Constructor Detail

VmStatusChangeEvent

public VmStatusChangeEvent(MonitoredHost host,
                           Set active,
                           Set started,
                           Set terminated)

Construct a new VmStatusChangeEvent instance.

Parameters:

host - the MonitoredHost that is the source of the event.

active - the set of currently active Java Virtual Machines

started - the set of Java Virtual Machines started since the last event.

terminated - the set of Java Virtual Machines terminated since the last event.

Method Detail

getActive

public Set getActive()

Return the set of currently active Java Virtual Machines. The set contains an Integer object holding the lvmid for each active Java Virtual Machine on the MonitoredHost.

Returns:

Set - a set of Integer objects containing the lvmid of each active Java Virtual Machine on the host. If there are no active Java Virtual Machines on the host, an empty Set is returned.

getStarted

public Set getStarted()

Return the set of Java Virtual Machines started since the last event notification. The set contains an Integer object holding the lvmid for each Java Virtual Machine started on the MonitoredHost since the last event notification.

Returns:

Set - a set of Integer objects containing the lvmid of each Java Virtual Machine started on the host. If no Java Virtual Machines were recently started on the host, an empty Set is returned.

getTerminated

public Set getTerminated()

Return the set of Java Virtual Machines terminated since the last event notification. The set contains an Integer object holding the lvmid for each Java Virtual Machine terminated on the MonitoredHost since the last event notification.

Returns:

Set - a set of Integer objects containing the lvmid of each Java Virtual Machine terminated on the host. If no Java Virtual Machines were recently terminated on the host, an empty Set is returned.
