ALL_REMOVED

@Deprecated
public static final int ALL_REMOVED

Deprecated.

Use multiple LAYER_REMOVED events instead, so that the listener knows what layers were removed.

Constructor Details

TLcdLayeredEvent

public TLcdLayeredEvent()

TLcdLayeredEvent

public TLcdLayeredEvent(ILcdLayered source,
 int id)

Creates an event with given source and change type.

Parameters:

source - the originating ILcdLayered of this event.

id - the type of change of this event. Can be one of STATE_CHANGED, LAYER_ADDED, LAYER_MOVED, LAYER_REMOVED, ALL_REMOVED.

TLcdLayeredEvent

public TLcdLayeredEvent(ILcdLayered source,
 int id,
 ILcdLayer aLayer)

Creates an event with given source, change type and layer for which the change occurred.

Parameters:

source - the originating ILcdLayered of this event.

id - the type of change of this event. Can be one of STATE_CHANGED, LAYER_ADDED, LAYER_MOVED, LAYER_REMOVED, ALL_REMOVED.

aLayer - the ILcdLayer for which a change occurred.

TLcdLayeredEvent

public TLcdLayeredEvent(ILcdLayered source,
 int id,
 ILcdLayer aLayer,
 int aOriginalIndex,
 int aNewIndex)

Creates an event with given source, change type, layer and index for which the change occurred.

Parameters:

source - the originating ILcdLayered of this event

id - the type of change of this event. Can be one of STATE_CHANGED, LAYER_ADDED, LAYER_MOVED, LAYER_REMOVED, ALL_REMOVED.

aLayer - the ILcdLayer for which a change occurred

aOriginalIndex - the index of the layer in the ILcdLayeredbefore the change, or -1 when the id is ALL_REMOVED or when the layer was added to the ILcdLayered

aNewIndex - the index of the layer in the ILcdLayered after the change, or -1 when the id is ALL_REMOVED or when the layer is removed from the ILcdLayered

• getOriginalIndex()
• getNewIndex()

Method Details

dispatch

public void dispatch(EventListener listener)

Description copied from interface: ILcdDispatchableEvent

Sends this ILcdDispatchableEvent to the given listener.

Specified by:

dispatch in interface ILcdDispatchableEvent

Specified by:

dispatch in class ALcdDispatchableEvent

Parameters:

listener - the listener that will receive this ILcdDispatchableEvent.

getID

public int getID()

Returns an ID indicating the type of event.

Returns:

the ID of this event, which indicates the type of event. The ID can be one of STATE_CHANGED, LAYER_ADDED, LAYER_MOVED, LAYER_REMOVED, ALL_REMOVED.

getLayered

public ILcdLayered getLayered()

Returns the ILcdLayered the change causing this event has occurred on.

Returns:

the ILcdLayered the change causing this event has occurred on.

getLayer

public ILcdLayer getLayer()

Returns the ILcdLayer which caused a change on the ILcdLayered, or null when no layer was set during the construction of this event.

Returns:

the ILcdLayer which caused a change on the ILcdLayered, or null when no layer was set during the construction of this event.

toString

public String toString()

Returns the source and a string representation of the type of event.

Overrides:

toString in class ALcdDispatchableEvent

Returns:

the source and a string representation of the type of event.

getOriginalIndex

public int getOriginalIndex()

Returns the index of the layer in getLayered() before the event occurred. In case of:

• LAYER_ADDED: the index will be -1, since the layer was not a part of the ILcdLayered before the event
• LAYER_REMOVED: the index is the old index of the removed layer, before the remove operation took place
• LAYER_MOVED: the index is the original index of the layer, before the move operation took place
• ALL_REMOVED: the index is irrelevant, and -1 will be returned

Returns:

the index of the ILcdLayer in the ILcdLayered before the event occurred, or -1 if no index was set

getNewIndex

public int getNewIndex()

Returns the index of the layer in getLayered() after the event occured. In case of:

• LAYER_ADDED: the index will be the index on which the layer was added.
• LAYER_REMOVED: the index will be -1, since the layer is no longer part of the ILcdLayered
• LAYER_MOVED: the index will be the new index of the layer, after the move operation took place
• ALL_REMOVED: the index is irrelevant, and -1 will be returned

Returns:

the index of the ILcdLayer in the ILcdLayered after the event occured, or -1 if no index was set
