Constructor Detail

AbstractDatasetChangedEvent

protected AbstractDatasetChangedEvent(DataSet dataSet)

Constructs a new AbstractDatasetChangedEvent.

Parameters:

dataSet - the dataset from which the event came from

Method Detail

fire

public abstract void fire(DataSetListener listener)

Calls the appropriate method of the listener for this event.

Parameters:

listener - dataset listener to notify about this event

getPrimitives

public abstract java.util.Collection<? extends OsmPrimitive> getPrimitives()

Returns list of primitives modified by this event.
WARNING This value might be incorrect in case of DataChangedEvent. It returns all primitives in the dataset when this method is called (live list), not list of primitives when the event was created

Returns:

List of modified primitives

getDataset

public DataSet getDataset()

Returns the dataset from which the event came from.

Returns:

the dataset from which the event came from

getType

public abstract AbstractDatasetChangedEvent.DatasetEventType getType()

Returns the type of dataset changed event.

Returns:

the type of dataset changed event

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
