DataChangedEvent

public DataChangedEvent(DataSet dataSet,
                        java.util.List<AbstractDatasetChangedEvent> events)

Constructs a new DataChangedEvent

Parameters:

dataSet - the dataset from which the event comes from

events - list of change events

DataChangedEvent

public DataChangedEvent(DataSet dataSet)

Constructs a new DataChangedEvent

Parameters:

dataSet - data set. Can be null

Method Detail

fire

public void fire(DataSetListener listener)

Description copied from class: AbstractDatasetChangedEvent

Calls the appropriate method of the listener for this event.

Specified by:

fire in class AbstractDatasetChangedEvent

Parameters:

listener - dataset listener to notify about this event

getPrimitives

public java.util.Collection<OsmPrimitive> getPrimitives()

Description copied from class: AbstractDatasetChangedEvent

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

Specified by:

getPrimitives in class AbstractDatasetChangedEvent

Returns:

List of modified primitives

getType

public AbstractDatasetChangedEvent.DatasetEventType getType()

Description copied from class: AbstractDatasetChangedEvent

Returns the type of dataset changed event.

Specified by:

getType in class AbstractDatasetChangedEvent

Returns:

the type of dataset changed event

getEvents

public java.util.List<AbstractDatasetChangedEvent> getEvents()

Returns list of events that caused this DataChangedEvent.

Returns:

List of events that caused this DataChangedEvent. Might be null
