All Implemented Interfaces:

java.util.Observer, java.lang.Runnable

public class NTPrintQBean

extends SNMPRunBean

implements java.util.Observer

This bean collects the names of the print queues installed on a NT server. The NT mib is described in the LAN Manager MIB II for Windows NT Objects . You will have to register to the MSDN before accessing this page.

The properties in the parent classes should be set, before calling the action() method. Via a PropertyChangeEvent the application/applet will be notified.

Constructor Detail

NTPrintQBean

public NTPrintQBean()

The default constructor.

NTPrintQBean

public NTPrintQBean(java.lang.String h,
                    int p)

The constructor that will set the host and the port no.

Parameters:

h - the hostname

p - the port no

See Also:

SNMPBean.setHost(java.lang.String), SNMPBean.setPort(int)

Method Detail

getLastUpdateDate

public java.util.Date getLastUpdateDate()

Returns the date of the moment when this bean was last updated. This might be null when the first time the update was not finished.

Returns:

the last update date

getIndices

public java.util.Enumeration getIndices()

Returns the indices of the NT print queues. The OID of this print queue is a concatenation of the name (svPrintQName) OID and the print queue specific index. The index should be used to get the other properties of this print queue.

See Also:

getIndex(String), svPrintQName

getIndex

public java.lang.String getIndex(java.lang.String name)

Returns the index of one of the print queues. The OID of this print queue is a concatenation of the name (svPrintQName) OID and the print queue specific index. The index should be used to get the other properties of this print queue.

Parameters:

name - The name of the print queue

Returns:

the print queue index, might be null if no print queue with such name exists

See Also:

getIndices(), getNames()

getNames

public java.util.Enumeration getNames()

Returns the names of the NT print queues (the list of svPrintQName).

getCount

public int getCount()

Returns the number of NT print queues.

action

public void action()

This method starts the action of the bean. It will initialises all variables before starting.

Overrides:

action in class SNMPBean

run

public void run()

Implements the running of the bean. It will send the Pdu, if the previous one is not still in flight.

Overrides:

run in class SNMPRunBean

See Also:

SNMPRunBean.isRunning()

update

public void update(java.util.Observable obs,
                   java.lang.Object ov)

This method is called when the Pdu response is received. When all answers are received it will fire the property change event. The answers are stored in a hashtable, this is done because the speed can only be calculated with the previous answer.

Specified by:

update in interface java.util.Observer
