Arc specific access methods.
This class represents the access methods that are specific to an arc. They also allow setting of rendering attributes.
Rendering attributes can be set directly to this geometry using the inherited TSLEntityBase::setRendering method. This is called 'Entity Rendering'.
Rendering can be applied to a large range of geometry using 'Feature Rendering' which is set by the datalayer using TSLDataLayer::addFeatureRendering which creates a featureID. The featureID can then have attributes applied to it using TSLDataLayer::setFeatureRendering.
A featureID can be applied to geometry on creation, or it can be added later using TSLEntityBase::featureID.
Valid Rendering Attributes for TSLArc:
The above is not a complete list, see TSLRenderingAttributeInt, TSLRenderingAttributeDouble and TSLRenderingAttributeBool for more details.
