RenderableLayer()
Creates a new RenderableLayer with a null delegateOwner |

RenderableLayer(Layer delegateOwner)
Creates a new RenderableLayer with the specified delegateOwner . |
Method Summary | |
---|---|
void |
addRenderable(Renderable renderable)
Adds the specified renderable to this layer's internal collection. |
void |
addRenderables(Iterable<? extends Renderable> renderables)
Adds the contents of the specified renderables to this layer's internal collection. |
protected void |
clearRenderables()
|
void |
dispose()
Disposes the contents of this layer's internal Renderable collection, but does not remove any elements from that collection. |

getActiveRenderables()
Returns the Iterable of currently active Renderables. |

getDelegateOwner()
Returns this layer's delegate owner, or null if none has been specified. |
int |
getNumRenderables()
|
double |
getOpacity()
Returns the layer's opacity value, which is ignored by this layer because each of its renderables typiically has its own opacity control. |
Iterable<Renderable> |
getRenderables()
Returns the Iterable of Renderables currently in use by this layer. |
void |
removeAllRenderables()
Clears the contents of this layer's internal Renderable collection. |
void |
removeRenderable(Renderable renderable)
Removes the specified renderable from this layer's internal collection, if it exists. |
void |
setOpacity(double opacity)
Opacity is not applied to layers of this type because each renderable typically has its own opacity control. |
void |
setRenderables(Iterable<Renderable> renderableIterable)
Overrides the collection of currently active Renderables with the specified renderableIterable . |

. This
layer will maintain a reference to renderableIterable
strictly for picking and rendering. This layer
will not modify the reference, or dispose of its contents. This will also clear and dispose of the internal
collection of Renderables, and will prevent any modification to its contents via addRenderable,
addRenderables, removeRenderables, or dispose
.
If the specified renderableIterable
is null, this layer will revert to maintaining its internal
collection.
