Method Details
-
globalInfo
Global info (if it exists) for the wrapped loader- Returns:
- the global info
-
setDB
public void setDB(boolean flag) -
setBeanContext
Set a bean context for this bean- Specified by:
setBeanContextin interfaceBeanContextChild- Overrides:
setBeanContextin classAbstractDataSource- Parameters:
bc- aBeanContextvalue
-
setLoader
Set the loader to use- Parameters:
loader- aweka.core.converters.Loadervalue
-
getStructure
Get the structure of the output encapsulated in the named event. If the structure can't be determined in advance of seeing input, or this StructureProducer does not generate the named event, null should be returned.- Specified by:
getStructurein interfaceStructureProducer- Parameters:
eventName- the name of the output event that encapsulates the requested output.- Returns:
- the structure of the output encapsulated in the named event or null if it can't be determined in advance of seeing input or the named event is not generated by this StructureProduce.
-
getLoader
Get the loader- Returns:
- a
weka.core.converters.Loadervalue
-
setWrappedAlgorithm
Set the loader- Specified by:
setWrappedAlgorithmin interfaceWekaWrapper- Parameters:
algorithm- a Loader- Throws:
IllegalArgumentException- if an error occurs
-
getWrappedAlgorithm
Get the loader- Specified by:
getWrappedAlgorithmin interfaceWekaWrapper- Returns:
- a Loader
-
startLoading
public void startLoading()Start loading data -
start
Start loading -
getStartMessage
Gets a string that describes the start action. The KnowledgeFlow uses this in the popup contextual menu for the component. The string can be proceeded by a '$' character to indicate that the component can't be started at present.- Specified by:
getStartMessagein interfaceStartable- Returns:
- a string describing the start action.
-
eventGeneratable
Returns true if the named event can be generated at this time- Specified by:
eventGeneratablein interfaceEventConstraints- Parameters:
eventName- the event- Returns:
- a
booleanvalue
-
addDataSourceListener

addDataSourceListenerin interfaceDataSource- Overrides:
addDataSourceListenerin classAbstractDataSource- Parameters:
dsl- aDataSourceListenervalue
-
removeDataSourceListener
Remove a listener- Specified by:
removeDataSourceListenerin interfaceDataSource- Overrides:
removeDataSourceListenerin classAbstractDataSource- Parameters:

connectionAllowedin interfaceBeanCommon- Parameters:
eventName- the name of the event- Returns:
- true if the object will accept a connection
-
connectionNotification
Notify this object that it has been registered as a listener with a source for receiving events described by the named event This object is responsible for recording this fact.- Specified by:
connectionNotificationin interfaceBeanCommon- Parameters:
eventName- the eventsource- the source with which this object has been registered as a listener
-
disconnectionNotification
Notify this object that it has been deregistered as a listener with a source for named event. This object is responsible for recording this fact.- Specified by:
disconnectionNotificationin interfaceBeanCommon- Parameters:
eventName- the eventsource- the source with which this object has been registered as a listener
