public Class GraphicsPrimitiveProxy

extends GraphicsPrimitive
Class Inheritance
GraphicsPrimitiveProxy Acts as a proxy for instances of GraphicsPrimitive, enabling lazy classloading of these primitives. This leads to a substantial savings in start-up time and footprint. In the typical case, it has been found that a small number of GraphicsPrimitive instance actually end up getting instantiated.

Note that the makePrimitive method should never be invoked on a GraphicsPrimitiveProxy object since they are instantiated as soon as they are found in the primitive list and never returned to the caller.
