- Constructor Detail
  - PDNameTreeNode
```
protected PDNameTreeNode()
```
    Constructor.
  - PDNameTreeNode
```
protected PDNameTreeNode(COSDictionary dict)
```
    Constructor.
    
    Parameters:
    dict - The dictionary that holds the name information.
- Method Detail
  - getCOSObject
```
public COSDictionary getCOSObject()
```
    Convert this standard java object to a COS object.
    
    Specified by:
    
    getCOSObject in interface COSObjectable
    
    Returns:
    The cos object that matches this Java object.
  - getParent
```
public PDNameTreeNode getParent()
```
    Returns the parent node.
    
    Returns:
    parent node
  - setParent
```
public void setParent(PDNameTreeNode parentNode)
```
    Sets the parent to the given node.
    
    Parameters:
    parentNode - the node to be set as parent
  - isRootNode
```
public boolean isRootNode()
```
    Determines if this is a root node or not.
    
    Returns:
    true if this is a root node
  - getKids
```
public List<PDNameTreeNode<T>> getKids()
```
    Return the children of this node. This list will contain PDNameTreeNode objects.
    
    Returns:
    The list of children or null if there are no children.
  - setKids
```
public void setKids(List<? extends PDNameTreeNode<T>> kids)
```
    Set the children of this named tree.
    
    Parameters:
    kids - The children of this named tree.
  - getValue
```
public T getValue(String name)
                                 throws IOException
```
    The name to retrieve.
    
    Parameters:
    name - The name in the tree.
    
    Returns:
    The value of the name in the tree.
    
    Throws:
    
    IOException - If an there is a problem creating the destinations.
  - getNames
```
public Map<String,T> getNames()
                                             throws IOException
```
    This will return a map of names. The key will be a string, and the value will depend on where this class is being used.
    
    Returns:
    ordered map of cos objects or null if dictionary contains no 'Names' entry
    
    Throws:
    
    IOException - If there is an error while creating the sub types.
  - convertCOSToPD
```
protected abstract T convertCOSToPD(COSBase base)
                                                   throws IOException
```
    Method to convert the COS value in the name tree to the PD Model object. The default implementation will simply return the given COSBase object. Subclasses should do something specific.
    
    Parameters:
    base - The COS object to convert.
    
    Returns:
    The converted PD Model object.
    
    Throws:
    
    IOException - If there is an error during creation.
  - createChildNode
```
protected abstract PDNameTreeNode<T> createChildNode(COSDictionary dic)
```
    Create a child node object.
    
    Parameters:
    dic - The dictionary for the child node object to refer to.
    
    Returns:
    The new child node object.
  - setNames
```
public void setNames(Map<String,T> names)
```
    Set the names of for this node. The keys should be java.lang.String and the values must be a COSObjectable. This method will set the appropriate upper and lower limits based on the keys in the map.
    
    Parameters:
    names - map of names to objects, or null
  - getUpperLimit
```
public String getUpperLimit()
```
    Get the highest value for a key in the name map.
    
    Returns:
    The highest value for a key in the map.
  - getLowerLimit
```
public String getLowerLimit()
```
    Get the lowest value for a key in the name map.
    
    Returns:
    The lowest value for a key in the map.
