SourceExpander
public class SourceExpander extends SimplePlugin (Code)
The Base SourceExpander class.

Inner Class :static class InputTasksP implements UnaryPredicate
Inner Class :static class ExpansionsP implements UnaryPredicate
Inner Class :static class OrganizationAssetsP implements UnaryPredicate

Field Summary
protected  UTILExpandexpandHelper
    
protected  LoggingServicelogger
    
protected  UTILPreferenceprefHelper
    
protected  UTILPrepPhraseprepHelper
    


Method Summary
public synchronized  voidexecute()
    
protected  booleanexpandTask(Task task)
     Create the original subtask to be sent to the first supplier in order to fill a SOURCE request.
protected synchronized  voidexpanderRollup(Expansion expansion)
     This method provides the fundamental logic for the Multiple Suppliers plugins. This method is called by the plugin's execute() method when a Source Task's Expansion is marked as changed.
protected  StringgetClusterName()
    
public  EnumerationgetInputTasks()
    
protected  LoggingServicegetLoggingService()
     Get the logging service, for subclass use.
protected  OrganizationgetNextSupplier(Task task, Organization curSupplier)
     Get next supplier from a list of suppliers in the WITHSUPPLIERS phrase of a task.
Parameters:
  task - the Task that contains a list of suppliers in a WITHSUPPLIERS phrase.
Parameters:
  curSupplier - the last supplier that was used.
public  EnumerationgetOrganizationAssets()
    
public  EnumerationgetOrganizationAssetsAdded()
    
public  EnumerationgetOrganizationAssetsChanged()
    
public  booleangetOrganizationAssetsHasChanged()
    
public  EnumerationgetOrganizationAssetsRemoved()
    
protected  VectorgetSuppliersList(Task task)
     Sublass implementations should override this method to provide the Vector of Organizations that should be used as suppliers for this task.
Parameters:
  task - the task that suppliers are needed for.
protected  voidhandleChangedTask(Task task)
     This method is meant to be overridden by subclasses for those instances where the sublass needs to do processing when a task change is detected.
final public  voidsetLoggingService(LoggingService bs)
     rely upon load-time introspection to set these services - don't worry about revokation.
protected  voidsetupSubscriptions()
     Standard SimplePlugin method.
protected  voidtransactInit()
     This method is meant to be overridden by subclasses for those instances where the subclass needs to do any initialization at the beginning of each execute() loop.

prefHelper

Method Detail
execute
public synchronized void execute()(Code)



expandTask
protected boolean expandTask(Task task)(Code)
Create the original subtask to be sent to the first supplier in order to fill a SOURCE request.
Parameters:
  task - the SOURCE task that needs to be expanded.



expanderRollup
protected synchronized void expanderRollup(Expansion expansion)(Code)
This method provides the fundamental logic for the Multiple Suppliers plugins. This method is called by the plugin's execute() method when a Source Task's Expansion is marked as changed. This method will detect if the SOURCE task is completely satisfied. If not, the next supplier will be identified and that Organization will be sent a task to help fulfill the SOURCE request. When the SOURCE task is completely satisfied or when there are no more suppliers to use, this method will rollup the results and notify the original requester.
Parameters:
  expansion - the Expansion object that has been marked as changed.



getClusterName
protected String getClusterName()(Code)



getInputTasks
public Enumeration getInputTasks()(Code)



getLoggingService
protected LoggingService getLoggingService()(Code)
Get the logging service, for subclass use.



getNextSupplier
protected Organization getNextSupplier(Task task, Organization curSupplier)(Code)
Get next supplier from a list of suppliers in the WITHSUPPLIERS phrase of a task.
Parameters:
  task - the Task that contains a list of suppliers in a WITHSUPPLIERS phrase.
Parameters:
  curSupplier - the last supplier that was used. the next supplier to use



getOrganizationAssets
public Enumeration getOrganizationAssets()(Code)



getOrganizationAssetsAdded
public Enumeration getOrganizationAssetsAdded()(Code)



getOrganizationAssetsChanged
public Enumeration getOrganizationAssetsChanged()(Code)



getOrganizationAssetsHasChanged
public boolean getOrganizationAssetsHasChanged()(Code)



getOrganizationAssetsRemoved
public Enumeration getOrganizationAssetsRemoved()(Code)



getSuppliersList
protected Vector getSuppliersList(Task task)(Code)
Sublass implementations should override this method to provide the Vector of Organizations that should be used as suppliers for this task.
Parameters:
  task - the task that suppliers are needed for. (ordered) list of Organizations that can serve as supplier for the input Task.



handleChangedTask
protected void handleChangedTask(Task task)(Code)
This method is meant to be overridden by subclasses for those instances where the sublass needs to do processing when a task change is detected. The defualt implementation of this method does nothing.
Parameters:
  task - a Task that has marked as changed.



setLoggingService
final public void setLoggingService(LoggingService bs)(Code)
rely upon load-time introspection to set these services - don't worry about revokation.



setupSubscriptions
protected void setupSubscriptions()(Code)
Standard SimplePlugin method. Store cluster name and setup subscriptions for input Tasks, Expansions and Allocations.



transactInit
protected void transactInit()(Code)
This method is meant to be overridden by subclasses for those instances where the subclass needs to do any initialization at the beginning of each execute() loop. The default implementation does nothing.
