private static final int
LIST_TYPE
Constant to denote - List types of available MBeans
private static final int
LIST_INSTANCE
Constant to denote - List available MBean names.
private static final int
LIST_TYPE_AND_INSTANCE
Constant to denote - List available MBean types and names.
Constructors Summary
MonitorListCommand(ObjectName mbeanName)
Create a MonitorListCommand to list available MBean types and names. This command will produce a list of all child MBeans in the form type.name.

param
mbeanName object name of the MBean


                                        
      
        this.objectName = mbeanName;
        this.actionCode = LIST_TYPE_AND_INSTANCE;
MonitorListCommand(ObjectName mbeanName, MonitoredObjectType type)
Create a MonitorListCommand to list available MBean names. This command will produce a list of names of all child MBeans of specified type.

param
mbeanName object name of the MBean
param
type type of the child MBeans

        this.objectName = mbeanName;
        this.actionCode = LIST_INSTANCE;
        this.monitoredObjectType = type.getTypeName();
Methods Summary
java.lang.ObjectrunCommand()
Run the command to produce a list. The method returns a String[] of length 0 or more.

throws
InstanceNotFoundException if the MBean is not found.
