Constructor Detail

TLcdLayeredSupport

public TLcdLayeredSupport(ILcdLayered aLayeredToSupport)

Creates a new TLcdLayeredSupport that works for the given ILcdLayered.

Parameters:

aLayeredToSupport - The layered to support.

TLcdLayeredSupport

public TLcdLayeredSupport()

Create a new TLcdLayeredSupport, without specifying the ILcdLayered which delegates his methods to this support. Make sure setLayeredToSupport(ILcdLayered) is called before using an instance of this class.

Method Detail

isFireInitialEvents

public static boolean isFireInitialEvents()

Returns true if some initial events are fired to a ILcdLayeredListener when it is added. Default is false.

Returns:

true if events should be fired to a ILcdLayeredListener that is added.

See Also:

setFireInitialEvents(boolean)

setFireInitialEvents

public static void setFireInitialEvents(boolean aFireInitialEvents)

Sets if some initial events are fired to a ILcdLayeredListener when it is added. Prior to version 6.0, the default behavior was true, meaning that a LAYER_REMOVED and LAYER_ADDED event were fired, for every layer, but only to the listener that was just added.

As of version 6.0 the default is false, meaning no events are fired to a ILcdLayeredListener when it is added. This is consistent with the behavior of all other listeners. For backward compatibility reasons, the old behavior can still be enabled, by setting this value to true.

This property can also be set by assigning 'true' or 'false' to the system property 'com.luciad.view.TLcdLayeredSupport.fireInitialEvents'. A system property can be set using the command line option -Dkey=value to java.

Parameters:

aFireInitialEvents - True if initial events are fired to a listener, false otherwise.

getLayeredToSupport

public ILcdLayered getLayeredToSupport()

Returns the ILcdLayered which delegates his methods to this support

Returns:

the ILcdLayered which delegates his methods to this support

setLayeredToSupport

public void setLayeredToSupport(ILcdLayered aLayeredToSupport)

Sets the ILcdLayered which delegates his methods to this support

Parameters:

aLayeredToSupport - the ILcdLayered which delegates his methods to this support

layerCount

public int layerCount()

Description copied from interface: ILcdLayered

Returns the number of ILcdLayer objects in this ILcdLayered.

Specified by:

layerCount in interface ILcdLayered

Returns:

the number of ILcdLayer objects in this ILcdLayered.

layers

public Enumeration layers()

Description copied from interface: ILcdLayered

Returns an Enumeration of all ILcdLayer objects currently in this ILcdLayered, starting from the bottom layer to the top layer.

Specified by:

layers in interface ILcdLayered

Returns:

an Enumeration of all ILcdLayer objects currently in this ILcdLayered, starting from the bottom layer to the top layer.

layersBackwards

public Enumeration layersBackwards()

Description copied from interface: ILcdLayered

Returns an Enumeration of all ILcdLayer objects currently in this ILcdLayered, starting from the top layer to the bottom layer.

Specified by:

layersBackwards in interface ILcdLayered

Returns:

an Enumeration of all ILcdLayer objects currently in this ILcdLayered, starting from the top layer to the bottom layer.

indexOf

public int indexOf(ILcdLayer aLayer)
            throws NoSuchElementException

Description copied from interface: ILcdLayered

Returns the index if the given layer is in the list.

Specified by:

indexOf in interface ILcdLayered

Parameters:

aLayer - the layer whose index to return

Returns:

the index of aLayer

Throws:

NoSuchElementException - if aLayer is not in the list

moveLayerAt

public void moveLayerAt(int aIndex,
                        ILcdLayer aLayer)
                 throws NoSuchElementException,
                        ArrayIndexOutOfBoundsException

Description copied from interface: ILcdLayered

Moves the given layer (which is already in ILcdLayered) to the existing index aIndex. When a layer is moved down, all layers in between the previous and future position of the given layer (including the layer at index aIndex) are moved one position up. When a layer is moved up, all layers in between the previous and future position of the given layer (including the layer at index aIndex) are moved one position down.

More formally, let previousIndex be the index of aLayer before the move. If previousIndex < aIndex, then the index of all ILcdLayer objects in from previousIndex + 1 to aIndex is decremented with 1. If previousIndex > aIndex, then the index of all ILcdLayer objects in from aIndex to previousIndex -1 is incremented with 1.

Specified by:

moveLayerAt in interface ILcdLayered

Parameters:

aIndex - the index of the position where to move the layer.

aLayer - the layer to move.

Throws:

NoSuchElementException - if aLayer is not in this ILcdLayered.

ArrayIndexOutOfBoundsException - if aIndex is not an index of one of the layers of this ILcdLayered.

getLayer

public ILcdLayer getLayer(int aIndex)
                   throws ArrayIndexOutOfBoundsException

Specified by:

getLayer in interface ILcdLayered

Parameters:

aIndex - the position of the layer to retrieve in the ILcdLayered.

Returns:

the ILcdLayer in this ILcdLayered with index aIndex.
