queryNames

public 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 and/or a Query expression, a specific managed object name (equivalent to testing whether an managed object is registered). When the object name is null or no domain and key properties are specified, all objects are selected (and filtered if a query is specified). It returns the set of ObjectNames for the managed objects selected.

Specified by:

queryNames in interface IIOPMBeanServer

Parameters:

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.

query - The query expression to be applied for selecting managed objects. If null no query expression will be applied for selecting managed objects.

Returns:

A set containing the ObjectNames for the managed objects selected. If no managed object satisfies the query, an empty list is returned.

Throws:

RemoteException

isRegistered

When the object name is null or no domain and key properties are specified, all objects are to be selected (and filtered if a query is specified). It returns the set of ObjectInstance objects (containing the ObjectName and the Java Class name) for the selected MBeans.

Parameters:

name - The object name pattern identifying the MBeans to be retrieved. If null or no domain and key properties are specified, all the MBeans registered will be retrieved.

query - The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.

Returns:

A set containing the ObjectInstance objects for the selected MBeans. If no MBean satisfies the query an empty list is returned.
