com.sun.jsftemplating.layout.descriptors.LayoutComponent

This class defines a LayoutComponent. A LayoutComponent describes a UIComponent to be instantiated. The method {@link #getType()} provides a{@link ComponentType} descriptor that is capable of providing a{@link com.sun.jsftemplating.component.factory.ComponentFactory}to perform the actual instantiation. This class also stores properties and facets (children) to be set on a newly instantiated instance.
