public abstract class IlvAbstractFlatListModel
extends Object
implements IlvFlatListModel, IlvDataConverter, Cloneable

This class is an implementation of the IlvFlatListModel interface which handles the notification to listeners of the model.

However, it does not constrain the nature of the objects stored in the model or of their attributes.

Since:

JViews 7.5

Creates a new instance.

Method Detail

startBatch

public void startBatch()

Starts a group of modifications.

Specified by:

startBatch in interface IlvFlatListModel

Specified by:

startBatch in interface IlvBatchable

fireModelEvent

public void fireModelEvent(FlatListModelEvent event)

Notifies the listeners of a model event.

endBatch

public void endBatch()

Terminates a group of modifications.

Specified by:

endBatch in interface IlvFlatListModel

Specified by:

endBatch in interface IlvBatchable

addFlatListModelListener

public void addFlatListModelListener(FlatListModelListener listener)

Adds a listener. It will be notified each time a change in the data or in the column metainformation occurs.

Specified by:

addFlatListModelListener in interface IlvFlatListModel

removeFlatListModelListener

public void removeFlatListModelListener(FlatListModelListener listener)

Removes a listener. Unregisters the given listener from the notification list.

Specified by:

removeFlatListModelListener in interface IlvFlatListModel

getSupportedEventsMask

public int getSupportedEventsMask()

Returns a bit mask denoting the optional kinds of events that are guaranteed to be sent by this model to the registered listeners.

This implementation returns 0. It ought to be overridden in subclasses.

Specified by:

getSupportedEventsMask in interface IlvFlatListModel

convertToDouble

public double convertToDouble(Object value)

Converts an object to a double. This method is used in getDoubleAt for columns that are not of type Double.

Specified by:

convertToDouble in interface IlvDataConverter

clone

public Object clone()

Returns a copy of this object.

Overrides:

clone in class Object
