```
public ResourceListDataNode(java.util.List resources)
```
    Constructs a new node whose children are the system resources named in a given list.
    
    Parameters:
    
    resources - a list of strings naming resources available from the class path
- Method Detail
  - 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
  - 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
  - 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:
    
    "."
  - 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.
