javax.management.j2ee Interface Management

所有父接口:
EJBObject, Remote
public interface Management
extends EJBObject

The Management interface provides the APIs to navigate and manipulate managed objects. The J2EE Management EJB component (MEJB) must implement this as its remote interface.

queryNames

Set queryNames(ObjectName name,
               QueryExp query)
               throws RemoteException
Gets the names of managed objects controlled by the MEJB. This method enables any of the following to be obtained: The names of all managed objects, the names of a set of managed objects specified by pattern matching on the ObjectName, a specific managed object name (equivalent to testing whether a managed object is registered). When the object name is null or no domain and key properties are specified, all objects are selected. It returns the set of J2EEObjectNames for the managed objects selected.

参数:
name - The object name pattern identifying the managed objects to be retrieved. If null or no domain and key properties are specified, all the managed objects registered will be retrieved.
返回:
A set containing the ObjectNames for the managed objects selected. If no managed object satisfies the query, an empty set is returned.
抛出异常:
RemoteException - A communication exception occurred during the execution of a remote method call

isRegistered

boolean isRegistered(ObjectName name)

Checks whether a managed object, identified by its object name, is already registered with the MEJB.

参数:
name - The object name of the managed object to be checked.
返回:
True if the managed object is already registered in the MEJB, false otherwise.
抛出异常:
RemoteException - A communication exception occurred during the execution of a remote method call

getMBeanCount

Integer getMBeanCount()
