Class RenderContextFactory

public class RenderContextFactory

extends Object

This class is a factory of RenderContext instances. Ideally, only the first context acquired by an application should be created by this class. Other contexts should be created as children of that first context, and so on.

The above approach is a nice way to have a context that is shared globally, and child contexts that are intented to hold state that is specific to some parts of the application.
