Enclosing class:

VPFAutoFeatureGraphicWarehouse

protected abstract static class VPFAutoFeatureGraphicWarehouse.FeaturePriorityHolder
extends java.lang.Object

A FeaturePriorityHolder represents a rendering order slot in a list of feature types to be rendered. It is responsible for evaluating attributes of a VPF feature and determining if a particular feature matches what this priority holder represents. It can then provide an OMGraphicList for those features that match its attribute conditions.
