Method Details

setIndex

public void setIndex(int i)

Sets the index of the interface that will be requested.

Parameters:

i - the index

See Also:

• getIndex()

getIndex

public int getIndex()

Returns the index of the interface.

Returns:

the index

See Also:

• setIndex(int)

getDescription

public String getDescription()

Returns the description of the interface.

Returns:

the description

getOperStatusString

public 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 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.

Specified by:

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.

Specified by:

run in interface Runnable

Specified by:

run in class SNMPRunBean

See Also:

• SNMPRunBean.isRunning()

update

public void update(Observable obs,
 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 Observer
