LuciadLightspeedInterface ILcyGXYLayerOrderManager

All Known Implementing Classes:

TLcyGXYLayerOrderManager

public interface ILcyGXYLayerOrderManager

Manages the layer ordering in a gxy view. When new layers are added, this manager is responsible to put them in the correct position.

The manager must work both actively and passively: the layers can be added using its insertGXYLayer method or they can simply be added to the associated gxy view without further notice.

Method Summary

Modifier and Type	Method and Description
boolean	canMoveGXYLayerDown(ILcdGXYLayer aGXYLayer) Returns true if the given gxy layer can be moved down without violating the layer ordering.
boolean	canMoveGXYLayerUp(ILcdGXYLayer aGXYLayer) Returns true if the given gxy layer can be moved up without violating the layer ordering.
ILcdGXYView	getGXYView() Return the gxy view associated with this layer order manager.
void	insertGXYLayer(ILcdGXYLayer aGXYLayer, int aGXYLayerType, int aModelType) Method to insert the given layer to the given gxy view.
void	moveLayerBottom(ILcdGXYLayer aGXYLayer) Moves the given layer to the bottom of the view, but respects the layer ordering.
void	moveLayerDown(ILcdGXYLayer aGXYLayer) Moves the given layer downwards.
void	moveLayerTop(ILcdGXYLayer aGXYLayer) Moves the given layer to the top of the view, but respects the layer ordering.
void	moveLayerUp(ILcdGXYLayer aGXYLayer) Moves the given layer upwards.

Method Detail

getGXYView

ILcdGXYView getGXYView()

Return the gxy view associated with this layer order manager.

Returns:

the gxy view associated with this layer order manager.

insertGXYLayer

void insertGXYLayer(ILcdGXYLayer aGXYLayer,
                    int aGXYLayerType,
                    int aModelType)

Method to insert the given layer to the given gxy view.

Parameters:

aGXYLayer - The layer to insert.

aGXYLayerType - The layer type of the layer.

aModelType - The model type of the model of the layer.

canMoveGXYLayerUp

boolean canMoveGXYLayerUp(ILcdGXYLayer aGXYLayer)

Returns true if the given gxy layer can be moved up without violating the layer ordering.

Parameters:

aGXYLayer - The layer to test.

Returns:

true if the given gxy layer can be moved up.

canMoveGXYLayerDown

boolean canMoveGXYLayerDown(ILcdGXYLayer aGXYLayer)

Returns true if the given gxy layer can be moved down without violating the layer ordering.

Parameters:

aGXYLayer - The layer to test.

Returns:

true if the given gxy layer can be moved down.

moveLayerUp

void moveLayerUp(ILcdGXYLayer aGXYLayer)

Moves the given layer upwards.

This method should only be called if canMoveGXYLayerUp for the same layer returns true.

Parameters:

aGXYLayer - The layer to move.

canMoveGXYLayerUp(com.luciad.view.gxy.ILcdGXYLayer)

moveLayerDown

void moveLayerDown(ILcdGXYLayer aGXYLayer)

Moves the given layer downwards.

This method should only be called if canMoveGXYLayerDown for the same layer returns true.

Parameters:

aGXYLayer - The layer to move.

canMoveGXYLayerDown(com.luciad.view.gxy.ILcdGXYLayer)

moveLayerTop

void moveLayerTop(ILcdGXYLayer aGXYLayer)

Moves the given layer to the top of the view, but respects the layer ordering.

This method should only be called if canMoveGXYLayerUp for the same layer returns true.

Parameters:

aGXYLayer - The layer to move.

See Also:

canMoveGXYLayerUp(com.luciad.view.gxy.ILcdGXYLayer)

moveLayerBottom

void moveLayerBottom(ILcdGXYLayer aGXYLayer)

Moves the given layer to the bottom of the view, but respects the layer ordering.

This method should only be called if canMoveGXYLayerDown for the same layer returns true.

Parameters:

aGXYLayer - The layer to move.
