  - HDUDataNode
```
public HDUDataNode(nom.tam.fits.Header hdr,
                   FITSDataNode.ArrayDataMaker hdudata)
            throws NoSuchDataException
```
    Initialises a HDUDataNode from a Header object.
    
    Parameters:
    
    hdr - a FITS header object from which the node is to be created
    
    hdudata - an object capable of returning the HDU data
    
    Throws:
    
    NoSuchDataException
- Method Detail
  - 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
  - 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
  - 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
  - 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:
    
    "."
  - getPathElement
```
public java.lang.String getPathElement()
```
    Description copied from class: DefaultDataNode
    
    The DefaultDataNode implementation returns the label as a default path element.
    
    Specified by:
    
    getPathElement in interface DataNode
    
    Overrides:
    
    getPathElement in class DefaultDataNode
    
    Returns:
    
    the node's label
  - getHDUIndex
```
public int getHDUIndex()
```
  - getHduType
