- Method Detail
  - getName
```
public java.lang.String getName()
```
    Description copied from interface: DataNode
    
    Gets the name of this object. This is an intrinsic property of the object.
    
    Specified by:
    
    getName in interface DataNode
    
    Overrides:
    
    getName in class DefaultDataNode
    
    Returns:
    
    the name of the object
  - getNodeTLA
```
public java.lang.String getNodeTLA()
```
    Description copied from class: DefaultDataNode
    
    The DefaultDataNode implementation returns the string "...".
    
    Specified by:
    
    getNodeTLA in interface DataNode
    
    Overrides:
    
    getNodeTLA in class DefaultDataNode
    
    Returns:
    
    "..."
  - getNodeType
```
public java.lang.String getNodeType()
```
    Description copied from interface: DataNode
    
    Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.
    
    Specified by:
    
    getNodeType in interface DataNode
    
    Overrides:
    
    getNodeType in class DefaultDataNode
    
    Returns:
    
    a short description of the type of this DataNode
  - getPathSeparator
```
public java.lang.String getPathSeparator()
```
    Description copied from class: DefaultDataNode
    
    Returns a default separator string.
    
    Specified by:
    
    getPathSeparator in interface DataNode
    
    Overrides:
    
    getPathSeparator in class DefaultDataNode
    
    Returns:
    
    "."
  - getParentObject
```
public java.lang.Object getParentObject()
```
    Description copied from interface: DataNode
    
    Returns an object which is in some sense the parent of the one this node is based on. The parent is not a DataNode, it is something which may get fed to a DataNodeFactory to create DataNode. If no such object exists, which may well be the case, null should be returned.
    
    Specified by:
    
    getParentObject in interface DataNode
    
    Overrides:
    
    getParentObject in class DefaultDataNode
    
    Returns:
    
    an object which is the parent of this one, or null
  - getDescription
```
public java.lang.String getDescription()
```
    Description copied from interface: DataNode
    
    Gets a concise description of this object. The form of the description will depend on the type of node, but it might detail the shape or type of data represented, or otherwise give some information additional to the name. It should not include the return value of the getName method, since they may be presented together. It should be on one line, and preferably no longer than around 70 characters. The null value may be returned if there is nothing to say.
    
    Specified by:
    
    getDescription in interface DataNode
    
    Overrides:
    
    getDescription in class DefaultDataNode
    
    Returns:
    
    a short string describing this object
  - getChildMaker
```
public DataNodeFactory getChildMaker()
```
    Description copied from interface: DataNode
    
    Gets the factory which should in general be used to generate descendant nodes.
    
    Specified by:
    
    getChildMaker in interface DataNode
    
    Overrides:
    
    getChildMaker in class DefaultDataNode
    
    Returns:
    
    the factory used for generating children
  - allowsChildren
```
public boolean allowsChildren()
```
    Description copied from class: DefaultDataNode
    
    The DefaultDataNode implementation of this method returns false.
    
    Specified by:
    
    allowsChildren in interface DataNode
    
    Overrides:
    
    allowsChildren in class DefaultDataNode
    
    Returns:
    
    true if the node is of a type which can have child nodes, false otherwise
  - getChildIterator
```
public java.util.Iterator getChildIterator()
```
    Description copied from class: DefaultDataNode
    
    The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).
    
    Specified by:
    
    getChildIterator in interface DataNode
    
    Overrides:
    
    getChildIterator in class DefaultDataNode
    
    Returns:
    
    an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.
  - configureDetail
```
public void configureDetail(DetailViewer dv)
```
    Description copied from class: DefaultDataNode
    
    No custom configuration is performed.
    
    Specified by:
    
    configureDetail in interface DataNode
    
    Overrides:
    
    configureDetail in class DefaultDataNode
    
    Parameters:
    
    dv - the detail viewer which this node is given an opportunity to configure
  - addVOComponentViews
```
public static void addVOComponentViews(DetailViewer dv,
                                       uk.ac.starlink.votable.VOElement voel)
```
  - getSource
```
public static javax.xml.transform.dom.DOMSource getSource(uk.ac.starlink.votable.VOElement voel)
```
    Returns a DOM source associated with a given VO Element.
    
    Parameters:
    
    voel - element
    
    Returns:
    
    source
