Detailed Description

Node that groups other nodes.

This has influence on the Node.IsFeature property (a node under the Root CategoryNode) and is used in graphical user interfaces.

Constructor & Destructor Documentation

CategoryNode() [1/2]

CategoryNode

(

string

name

)

Creates a new CategoryNode with the given name .

If the name does not contain a namespace prefix the Namespace.Custom is used.

You must add this node to a NodeMap before most operations are possible.

Parameters

name	Name with optional namespace prefix.

CategoryNode() [2/2]

CategoryNode	(	string	name,
		Namespace	nameSpace
	)

Creates a new CategoryNode with the given name and nameSpace .

You must add this node to a NodeMap before most operations are possible.

Parameters

name	Node name without namespace prefix.
nameSpace	Namespace to place the node in.
