Method Detail

update

void update()

Prepare this Renderable for rendering might be better.

render

void render(com.tomtom.pnd.maplib.Renderer renderer)

Renders this Renderable, using whatever state the OpenGL context is in.

Parameters:

renderer - The Renderer's instance that renders this Renderable.

release

void release()

Releases any resources this Renderable acquired, which may include GPU memory.

isValid

boolean isValid()

Returns:

true if Renderable can be rendered by CustomOverlayRenderer.

setVisibility

void setVisibility(boolean isVisible)

Sets the visibility of this Renderable.

Parameters:

isVisible - If true, then the primitive is visible; if false, it is not.

isVisible

boolean isVisible()

Returns the visibility of this Renderable.

Returns:

true if the primitive is to be visible; false if it is not.

setZIndex

void setZIndex(int zIndex)

Sets the zIndex of this Renderable. Renderable with higher zIndices are drawn above those with lower indices.

Parameters:

zIndex - the zIndex of this Renderable.

getZIndex

int getZIndex()

Gets the zIndex of this Renderable.

Returns:

the zIndex of the Renderable.

registerDataChangeListener

void registerDataChangeListener(com.tomtom.pnd.maplib.DataChangeListener changeListener)

Adds new DataChangeListener to Renderable.

Parameters:

changeListener - DataChangeListener instance

unregisterDataChangeListener

void unregisterDataChangeListener(com.tomtom.pnd.maplib.DataChangeListener changeListener)

removes DataChangeListener from Renderable.

Parameters:

changeListener - DataChangeListener instance
