Method Summary

Modifier and Type	Method and Description

Method Detail

getShape

ILcdShape getShape(Set<Object> aComposingElements,
                   ILcdModel aOriginalModel)

Returns the shape in model coordinates for the cluster that will be composed of the given set of elements. This method is called while a read lock on aOriginalModel is already acquired.

There are some additional things to take into account when using a custom shape.

• The returned shape should be a standard shape implementation provided by LuciadLightspeed, OR, if it is a custom shape implementation, a shape that does not implement ILcd2DEditableShape.
• The returned shape's equals and hashCode implementations should be well-behaved.
• If you include the cluster elements in your styling of the cluster, you must make sure these elements are not edit targets.

Parameters:

aComposingElements - The composing elements for the cluster for which a shape needs to be provided. Do not modify.

aOriginalModel - The original model, from which the composing elements originate. It can be used to for example retrieve the model descriptor or model reference from. Do not modify.

Returns:

The cluster shape in model coordinates.
