Examples of groovy.util.Node

groovy.util.Node
Represents an arbitrary tree node which can be used for structured metadata or any arbitrary XML-like tree. A node can have a name, a value and an optional Map of attributes. Typically the name is a String and a value is either a String or a List of other Nodes, though the types are extensible to provide a flexible structure, e.g. you could use a QName as the name which includes a namespace URI and a local name. Or a JMX ObjectName etc. So this class can represent metadata like {foo a=1 b="abc"} or nested metadata like {foo a=1 b="123" { bar x=12 text="hello" }} @author James Strachan @author Paul King @version $Revision: 19450 $
