All Implemented Interfaces:

java.util.Observer, java.lang.Runnable

public class OneInterfaceBean

extends SNMPRunBean

implements java.util.Observer

This bean collects information about one interface.

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

                        int p)

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

Parameters:

h - the hostname

p - the port no

Method Detail

setIndex

public void setIndex(int i)

Sets the index of the interface that will be requested.

Parameters:

i - the index

See Also:

getIndex

public int getIndex()

Returns the index of the interface.

Returns:

the index

See Also:

getDescription

public java.lang.String getDescription()

Returns the description of the interface.

Returns:

the description

getOperStatusString

public java.lang.String getOperStatusString()

Returns the operation state of the interface.

Returns:

the operation state

getSpeed

public long getSpeed()

Returns the speed (bits per second) of the interface.

Returns:

the speed

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

action

public void action()

This method starts sending the SNMP request. All properties should be set before this method is called. The actual sending will take place in the run method. It makes a new snmp context and initialises all variables before starting.

Overrides:

action in class SNMPBean

run

public void run()

The run method according to the Runnable interface. This method will send the Pdu request, 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)

The update method according to the Observer interface, it will be called when the Pdu response is received. The speed is calculated with the previous answer, after that the property change event is fired.

Specified by:

update in interface java.util.Observer
