public interface ParentNode<N extends Node>
extends Node
```
A node that may have children in the parse tree.
Important: Do not use outside of Soy code (treat as superpackage-private).
The parameter N represents the interface or class that is the superclass of all possible children for this ParentNode. E.g. for a Soy parse tree node, N is usually SoyNode, but for SoyFileSetNode N is SoyFileNode, for SoyFileNode N is TemplateNode, etc; for a Soy expression parse tree, N is usually ExprNode.

- Method Detail
  - numChildren
```
int numChildren()
```
    Gets the number of children.
    
    Returns:
    The number of children.
  - getChild
```
N getChild(int index)
```
    Gets the child at the given index.
    
    Parameters:
    index - The index of the child to get.
    
    Returns:
    The child at the given index.
  - getChildIndex
```
int getChildIndex(N child)
```
    Finds the index of the given child.
    
    Parameters:
    child - The child to find the index of.
    
    Returns:
    The index of the given child, or -1 if the given child is not a child of this node.
  - getChildren
```
List<N> getChildren()
```
    Gets the list of children. Note: The returned list may not be a copy. Please do not modify the list directly. Instead, use the other methods in this class that are intended for modifying children. Also, if you're iterating over the children list as you're modifying it, then you should first make a copy of the children list to iterate over, in order to avoid ConcurrentModificationException.
    
    Returns:
    The list of children.
  - addChild
```
void addChild(N child)
```
    Adds the given child.
    
    Parameters:
    child - The child to add.
  - addChild
```
void addChild(int index,
            N child)
```
    Adds the given child at the given index (shifting existing children if necessary).
    
    Parameters:
    index - The index to add the child at.
    child - The child to add.
  - removeChild
```
void removeChild(int index)
```
    Removes the child at the given index.
    
    Parameters:
    index - The index of the child to remove.
  - removeChild
```
void removeChild(N child)
```
    Removes the given child.
    
    Parameters:
    child - The child to remove.
  - replaceChild
```
void replaceChild(int index,
                N newChild)
```
    Replaces the child at the given index with the given new child.
    
    Parameters:
    index - The index of the child to replace.
    newChild - The new child.
  - replaceChild
```
void replaceChild(N currChild,
                N newChild)
```
    Replaces the given current child with the given new child.
    
    Parameters:
    currChild - The current child to be replaced.
    newChild - The new child.
  - clearChildren
```
void clearChildren()
```
    Clears the list of children.
  - addChildren
```
void addChildren(List<? extends N> children)
```
    Adds the given children.
    
    Parameters:
    children - The children to add.
  - addChildren
```
void addChildren(int index,
               List<? extends N> children)
```
    Adds the given children at the given index (shifting existing children if necessary).
    
    Parameters:
