All Implemented Interfaces:

java.lang.Runnable

public class NTDelRateJobClass
extends JobClass

This class implements a SLAMD job for removing user accounts from a Windows NT system. Note that the client running this job MUST be running on a Windows NT system as an administrator. This job is hard-coded to work with user entries created using the NT AddRate job, so it will only delete users with a username of "user.{number}", where {number} is a sequentially incrementing value. The deletes are performed using the command:

NET USER {username} /DELETE

Constructor Detail

NTDelRateJobClass

public NTDelRateJobClass()

The default constructor used to create a new instance of the add thread. The only thing it should do is to invoke the superclass constructor. All other initialization should be performed in the initialize method.

Method Detail

getJobName

public java.lang.String getJobName()

Retrieves the name of the job performed by this job thread.

Specified by:

getJobName in class JobClass

Returns:

The name of the job performed by this job thread.

getJobDescription

public java.lang.String getJobDescription()

Retrieves a description of the job performed by this job thread.

Specified by:

getJobDescription in class JobClass

Returns:

A description of the job performed by this job thread.

getJobCategoryName

public java.lang.String getJobCategoryName()

Retrieves the name of the category in which this job class exists. This is used to help arrange the job classes in the administrative interface.

Overrides:

getJobCategoryName in class JobClass

Returns:

The name of the category in which this job class exists.

getParameterStubs

public ParameterList getParameterStubs()

Retrieve a parameter list that can be used to determine all of the customizable options that are available for this job.

Specified by:

getParameterStubs in class JobClass

Returns:

A parameter list that can be used to determine all of the customizable options that are available for this job.

getStatTrackerStubs

public StatTracker[] getStatTrackerStubs(java.lang.String clientID,
                                         java.lang.String threadID,
                                         int collectionInterval)

Retrieves the set of stat trackers that will be maintained by this job class. The stat trackers returned by this method do not have to actually contain any statistics -- the display name and stat tracker class should be the only information that callers of this method should rely upon. Note that this list can be different from the list of statistics actually collected by the job in some cases (e.g., if the job may not return all the stat trackers it advertises in all cases, or if the job may return stat trackers that it did not advertise), but it is a possibility that only the stat trackers returned by this method will be accessible for some features in the SLAMD server.

Specified by:

getStatTrackerStubs in class JobClass

Parameters:

clientID - The client ID that should be used for the returned stat trackers.

threadID - The thread ID that should be used for the returned stat trackers.

collectionInterval - The collection interval that should be used for the returned stat trackers.

Returns:

The set of stat trackers that will be maintained by this job class.

getStatTrackers

public StatTracker[] getStatTrackers()

Retrieves the stat trackers that are maintained for this job thread.

Specified by:

getStatTrackers in class JobClass

Returns:

The stat trackers that are maintained for this job thread.

validateJobInfo

public void validateJobInfo(int numClients,
                            int threadsPerClient,

                            java.util.Date startTime,
                            java.util.Date stopTime,
                            int duration,
