public class BridgeContext
extends java.lang.Object
implements ErrorConstants, org.apache.batik.css.engine.CSSContext

This class represents a context used by the various bridges and the builder. A bridge context is associated to a particular document and cannot be reused. The context encapsulates the dynamic bindings between DOM elements and GVT nodes, graphic contexts such as a GraphicsNodeRenderContext, and the different objects required by the GVT builder to interpret a SVG DOM tree such as the current viewport or the user agent.
