Constructor Detail

SVGGraph2DRenderer

public SVGGraph2DRenderer()

Creates a new instance of SVGGraph2DRenderer

Method Detail

setSVGIOHandler

public void setSVGIOHandler(SVGIOHandler ioh)

Sets the SVGIOHandler this renderer is working with. This method will be used by SVGIOHandler to make itself known to this class.

getSVGIOHandler

protected SVGIOHandler getSVGIOHandler()

Returns the SVGIOHandler this renderer is working with.

getSVGDocument

protected Document getSVGDocument()

Returns the document that is used as factory for the nodes in the DOM tree of the SVG that is generated by the renderer's associated SVGIOHandler.

Note: Adding nodes to this document will have no effect regarding the SVG that is generated by the renderer's associated SVGIOHandler.

getTopLevelGroup

protected Element getTopLevelGroup()

Returns the top level group element of the SVG document to which graphical representation of nodes and edges will be added.

setTopLevelGroup

protected void setTopLevelGroup(Element element)

Sets the top level group element of the SVG document to which graphical representation of nodes and edges will be added.

createElement

protected Element createElement(String tag)

Creates a DOM element with the given name that can be added to the SVG document.

To create a hyperlink element <a> one would use as argument the string "a".

createCDATASection

protected CDATASection createCDATASection(String content)

Creates a character data section that can be added to the SVG document. CDATA sections must be used to embed javascript functions in the SVG document.

insertNodeAbove

protected void insertNodeAbove(Node toBeInsertedNode,
                               Node refNode)

Adds a DOM node to the SVG document. The node will be inserted above refNode, i.e. the node becomes the parent of refNode and the former parent of refNode will become the parent of the to-be-inserted node.

insertNodeBelow

protected void insertNodeBelow(Node toBeInsertedNode,
                               Node refNode)

Adds a DOM node to the SVG document. The node will be inserted below refNode, i.e. refNode will become the parent of the inserted node and all children of refNode will become children of the to-be-inserted node.

addToSVGDefinition

protected void addToSVGDefinition(Element element)

Adds a DOM element to to the definition block of the SVG document. The definition block is the right place for javascript definitions and other global stuff.

writeDocument

protected void writeDocument(Node svgDocument,
                             Writer writer)
                      throws IOException

Throws:

IOException
