Method Detail

makeNode

public Node makeNode(java.lang.String name,
                     FilteredProperties props)

Description copied from interface: NodeMaker

Create a Node for a named menu item. This is allowed to return null to indicate that nodes of this type are disabled/empty and should be suppressed. The NavigationMenuService can be configured to substitute a different node in this case (for example to host child nodes added by the configuration).

Automatic child nodes can be added in this method and will appear first. Followed by nodes from the configuration then nodes from NodeMaker.addChildren(Node, String, FilteredProperties)

Parameters:

name - name of the node

props - FilteredProperties containing the navigation menu configuration

Returns:

Node

getTransitionFactory

protected TransitionFactory<K,T> getTransitionFactory(java.lang.String name,
                                                      FilteredProperties props)

get the TransitionFactory A sub-class can override this to hardwire a particular provider.

Parameters:

name -

props -

Returns:

childNode

public Node childNode(java.lang.String name,
                      T target,
                      K key,
                      FilteredProperties props)

setChildName

protected void setChildName(Node n,
                            T target)

Parameters:
