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:

handleDOMNodeInsertedEvent in interface BridgeUpdateHandler

handleDOMNodeRemovedEvent

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:

handleDOMCharacterDataModified in interface BridgeUpdateHandler

handleCSSEngineEvent

public void handleCSSEngineEvent(CSSEngineEvent evt)

Invoked when an CSSEngineEvent is fired.

Specified by:

handleCSSEngineEvent in interface BridgeUpdateHandler

handleAnimatedAttributeChanged

Invoked when the animated value of an animated attribute has changed.

Specified by:

handleAnimatedAttributeChanged in interface BridgeUpdateHandler

handleOtherAnimationChanged

Invoked when an 'other' animation value has changed.

Specified by:

handleOtherAnimationChanged in interface BridgeUpdateHandler
