All Implemented Interfaces:

Cloneable, Runnable

public class TopRegionalRC
extends AbstractRC

This class acts as a centralized RC or a root RC in a hierarchical model. It is responsible for generating a unique ID for each file name. Hence, the full name of the file will be "filename+uniqueID" when you use DataGridUser.getFullFilename(String)

Since:

GridSim Toolkit 4.0

Field Detail

DEFAULT_NAME

public static final String DEFAULT_NAME

Default name for this RC entity, which is "GridSim_TopRC". NOTE: This default name is useful when a user forgets to tell the DataGridUser or DataGridResource entity about the RC id.

Constructor Detail

TopRegionalRC

public TopRegionalRC(String name,
                     Link link)
              throws Exception

Creates a new Replica Catalogue (RC) entity.

Parameters:

name - this entity name

link - the link that this GridSim entity will use to communicate with other GridSim or Network entities.

Throws:

Exception - This happens when one of the input parameters is invalid.

TopRegionalRC

public TopRegionalRC(Link link)
              throws Exception

Creates a new Replica Catalogue (RC) entity with a default name.

Parameters:

link - the link that this GridSim entity will use to communicate with other GridSim or Network entities.

Throws:

Exception - This happens when the network link is null

Method Detail

processOtherEvent

protected boolean processOtherEvent(Sim_event ev)

Processes an incoming request that uses a user-defined tag. This method is useful for creating a new RC entity.

Specified by:

processOtherEvent in class AbstractRC

Parameters:

ev - a Sim_event object (or an incoming event or request)

Returns:

true if successful, false otherwise

registerOtherEntity

protected void registerOtherEntity()

Registers other information to a GIS entity -- THIS METHOD IS EMPTY

Specified by:

registerOtherEntity in class AbstractRC

processEndSimulation

protected void processEndSimulation()

Performs last activities before the end of a simulation -- THIS METHOD IS EMPTY

Specified by:

processEndSimulation in class AbstractRC

registerOriginalFile

public boolean registerOriginalFile(FileAttribute fAttr,
                                    int sourceID)

Register a file which is already stored in a resource before the start of simulation.
NOTE: A unique id of this file IS NOT available

Specified by:

registerOriginalFile in class AbstractRC

Parameters:

fAttr - a FileAttribute object

sourceID - the entity ID that stores this file

Returns:

true if successful, false otherwise
