Class Layers

java.lang.Object

com.nutiteq.layers.Layers

public class Layers
extends java.lang.Object

Container for all raster and vector layers of the map view.

The order in which layers are added is important for vector elements like Points, Lines
and Polygons. For these elements the layer ordering defines their draw order.
Other elements like NMLModels and Polygon3Ds are z ordered and are drawn using the depth buffer.
For Billboard elements like Markers and Labels, the layer ordering is unimportant, because
they will be sorted from back to front and drawn in that order on top of all other vector elements.

Method Detail

getCPtr

public static long getCPtr(Layers obj)

finalize

protected void finalize()

Overrides:

finalize in class java.lang.Object

delete

public void delete()

count

public int count()

Returns the current layer count.

Returns:

The layer count.

get

public Layer get(int index)

Returns the layer at the specified index.

Parameters:

index - The layer index to return. Must be between 0 and count (exclusive).

Returns:

The layer at the specified index.

insert

public void insert(int index,
                   Layer layer)

Inserts a new layer at the specified position.
All previous layers starting from this index will be moved to the next position.

Parameters:

index - The layer index. Must be between 0 and count (inclusive).

layer - The new layer.

add

public void add(Layer layer)

Adds a new layer to the layer stack. The new layer will be the last (and topmost) layer.

Parameters:

layer - The layer to be added.

remove

public boolean remove(Layer layer)

Removes a layer to the layer stack.

Parameters:

layer - The layer to be removed.

Returns:

True if the layer was removed. False otherwise (layer was not found).

getLayers

public LayerVector getLayers()

Returns a list of layers. The layers are in the order in which they were added.

Returns:

A vector of all previously added layers.
