Field Detail

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 Detail

SVGDocumentBridge

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

Method Detail

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

handleDOMAttrModifiedEvent

public void handleDOMAttrModifiedEvent(MutationEvent evt)
Invoked when an MutationEvent of type 'DOMAttrModified' is fired.

Specified by:
handleDOMAttrModifiedEvent in interface BridgeUpdateHandler

handleDOMNodeInsertedEvent

public void handleDOMNodeInsertedEvent(MutationEvent evt)
Invoked when an MutationEvent of type 'DOMNodeInserted' is fired.

Specified by:

public void handleDOMNodeRemovedEvent(MutationEvent evt)
Invoked when an MutationEvent of type 'DOMNodeRemoved' is fired.

Specified by:
handleDOMNodeRemovedEvent in interface BridgeUpdateHandler

handleDOMCharacterDataModified

public void handleDOMCharacterDataModified(MutationEvent evt)
Invoked when an MutationEvent of type 'DOMCharacterDataModified' is fired.

Specified by:

Invoked when an 'other' animation value has changed.

Specified by:

Disposes this BridgeUpdateHandler and releases all resources.

Specified by:
dispose in interface BridgeUpdateHandler
