org.apache.batik.bridge.SVGDocumentBridge
All Implemented Interfaces:
Bridge, BridgeUpdateHandler, DocumentBridge, SVGContext
public class SVGDocumentBridge extends Object implements DocumentBridge, BridgeUpdateHandler, SVGContext
Bridge class for an SVGDocument node.

  • Field Details

    • document

      protected Document document
      The document node this bridge is associated with.

    • node

      protected RootGraphicsNode node
      The graphics node constructed by this bridge.

    • ctx

      protected BridgeContext ctx
      The bridge context.

  • Constructor Details

    • SVGDocumentBridge

      public SVGDocumentBridge()
      Constructs a new bridge the SVG document.

  • Method Details

    • getNamespaceURI

      public String getNamespaceURI()
      Returns the namespace URI of the element this Bridge is dedicated to. Returns null, as a Document node has no namespace URI.
      Specified by:
      getNamespaceURI in interface Bridge

    • getLocalName

      public String getLocalName()
      Returns the local name of the element this Bridge is dedicated to. Returns null, as a Document node has no local name.
      Specified by:
      getLocalName in interface Bridge

    • getInstance

      public Bridge getInstance()
      Returns a new instance of this bridge.
      Specified by:
      getInstance in interface Bridge

    • createGraphicsNode

      public RootGraphicsNode createGraphicsNode(BridgeContext ctx, Document doc)
      Creates a GraphicsNode according to the specified parameters. This is called before children have been added to the returned GraphicsNode (obviously since you construct and return it).
      Specified by:
      createGraphicsNode in interface DocumentBridge
      Parameters:
      ctx - the bridge context to use
      doc - the document node that describes the graphics node to build
      Returns:
      a graphics node that represents the specified document node

    • buildGraphicsNode

      public void buildGraphicsNode(BridgeContext ctx, Document doc, RootGraphicsNode node)
      Builds using the specified BridgeContext and element, the specified graphics node. This is called after all the children of the node have been constructed and added, so it is safe to do work that depends on being able to see your children nodes in this method.
      Specified by:
      buildGraphicsNode in interface DocumentBridge
      Parameters:
      ctx - the bridge context to use
      doc - the document node that describes the graphics node to build
      node - the graphics node to build
