MonitoredObjectType

public class MonitoredObjectType extends Object
MonitoredObjectType represents the type of a monitored object. Many of monitored objects have same properties, even while they monitor different user objects. For example - application and standalone ejb module are both nothing more than containers of other objects -- application contains web module and ejb modules, whereas standalone ejb module contains beans of various types. This object facilitates use of same GenericMonitorMBean as MBean for both of them, but still distinguishes them.

Constructors Summary
private MonitoredObjectType(String type)
Creates a new instance of MonitoredObjectType using specified string type

param
type string representing the name of monitored object type


                              
       
        this(type, false);
private MonitoredObjectType(String type, boolean isSingleton)
Creates a new instance of MonitoredObjectType using specified string type and specified flag for singleton

param
type string representing the name of monitored object type
param
isSingleton denotes whether this type of monitored object has only one instance (in its context)

        this.typeName = type;
        this.isSingleton = isSingleton;
        objectMap.put(this.typeName, this);
Methods Summary
public static com.sun.enterprise.admin.monitor.registry.MonitoredObjectTypegetMonitoredObjectType(java.lang.String typeName)
Get a MonitoredObjectType instance for the specified string type.

param
typeName string representing MonitoredObjectType
throws
IllegalArgumentException if the specified type name is not known.

        MonitoredObjectType type = getMonitoredObjectTypeOrNull(typeName);
        if (type == null) {
			//String msg = localStrings.getString( "admin.monitor.unknown_type_name", typeName );
            String msg = "admin.monitor.unknown_type_name:"+typeName;
            throw new IllegalArgumentException( msg );
        }
        return type;
static com.sun.enterprise.admin.monitor.registry.MonitoredObjectTypegetMonitoredObjectTypeOrNull(java.lang.String typeName)
Get a MonitoredObjectType instance for the specified string type. If the specified type is not known, the method returns null.

param
typeName string representing MonitoredObjectType

        MonitoredObjectType type = null;
        if (objectMap != null && typeName != null) {
            type = (MonitoredObjectType)objectMap.get(typeName);
        }
        return type;
public java.lang.StringgetTypeName()
Get type of this "MonitoredObjectType" as string

return
Monitored object type as string

        return typeName;
public booleanisSingleton()
Is instance of this type of MonitorMBean singleton. For example, there can only be one pool for every stateless session bean, so a MonitoredObjectType of type MonitoredObjectType.BEAN_POOL is a singleton.

return
true if this type of object can have atmost one instance within its context, false otherwise.

        return isSingleton;
public java.lang.StringtoString()
A string representation. The return value of this method is same as that of method getTypeName.

return
A string representation of this MonitoredObjectType

        return typeName;
