NodeAddData (Apache Commons Configuration 1.10 API)

java.lang.Object
- org.apache.commons.configuration.tree.NodeAddData

```
public class NodeAddData
extends Object
```
A simple data class used by ExpressionEngine to store the results of the prepareAdd() operation.

If a new property is to be added to a configuration, the affected Configuration object must know, where in its hierarchy of configuration nodes new elements have to be added. This information is obtained by an ExpressionEngine object that interprets the key of the new property. This expression engine will pack all information necessary for the configuration to perform the add operation in an instance of this class.

Information managed by this class contains:
- the configuration node, to which new elements must be added
- the name of the new node
- whether the new node is a child node or an attribute node
- if a whole branch is to be added at once, the names of all nodes between the parent node (the target of the add operation) and the new node

- Constructor Detail
  - NodeAddData
```
public NodeAddData()
```
    Creates a new, uninitialized instance of NodeAddData.
  - NodeAddData
```
public NodeAddData(ConfigurationNode parent,
           String nodeName)
```
    Creates a new instance of NodeAddData and sets the most important data fields.
    
    Parameters:
    parent - the parent node
    nodeName - the name of the new node
- Method Detail
  - isAttribute
```
public boolean isAttribute()
```
    Returns a flag if the new node to be added is an attribute.
    
    Returns:
    true for an attribute node, false for a child node
  - setAttribute
```
public void setAttribute(boolean attribute)
```
    Sets the attribute flag. This flag determines whether an attribute or a child node will be added.
    
    Parameters:
    attribute - the attribute flag
  - getNewNodeName
```
public String getNewNodeName()
```
    Returns the name of the new node.
    
    Returns:
    the new node's name
  - setNewNodeName
```
public void setNewNodeName(String newNodeName)
```
    Sets the name of the new node. A node with this name will be added to the configuration's node hierarchy.
    
    Parameters:
    newNodeName - the name of the new node
  - getParent
```
public ConfigurationNode getParent()
```
    Returns the parent node.
    
    Returns:
    the parent node
  - setParent
```
public void setParent(ConfigurationNode parent)
```
    Sets the parent node. New nodes will be added to this node.
    
    Parameters:
    parent - the parent node
  - getPathNodes
```
public List<String> getPathNodes()
```
    Returns a list with further nodes that must be added. This is needed if a complete branch is to be added at once. For instance imagine that there exists only a node database. Now the key database.connection.settings.username (assuming the syntax of the default expression engine) is to be added. Then username is the name of the new node, but the nodes connection and settings must be added to the parent node first. In this example these names would be returned by this method.
    
    Returns:
    a list with the names of nodes that must be added as parents of the new node (never null)
  - addPathNode
```
public void addPathNode(String nodeName)
```
    Adds the name of a path node. With this method an additional node to be added can be defined.
    
    Parameters:
    nodeName - the name of the node

    getPathNodes()
