public abstract class IlvAbstractFlatSetModel
extends Object
implements IlvFlatSetModel, IlvDataConverter, Cloneable

This class is an implementation of the IlvFlatSetModel interface which handles the notification to the 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 IlvFlatSetModel

Specified by:

startBatch in interface IlvBatchable

fireModelEvent

public void fireModelEvent(FlatSetModelEvent event)

Notifies the listeners of a model event.

endBatch

public void endBatch()

Terminates a group of modifications.

Specified by:

endBatch in interface IlvFlatSetModel

Specified by:

endBatch in interface IlvBatchable

addFlatSetModelListener

public void addFlatSetModelListener(FlatSetModelListener listener)

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

Specified by:

addFlatSetModelListener in interface IlvFlatSetModel

removeFlatSetModelListener

public void removeFlatSetModelListener(FlatSetModelListener listener)

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

Specified by:

removeFlatSetModelListener in interface IlvFlatSetModel

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 IlvFlatSetModel

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
