MixinParentNode (Closure Templates)

java.lang.Object
- com.google.template.soy.basetree.MixinParentNode<N>

```
public final class MixinParentNode<N extends Node>
extends Object
```
Mixin implementation of the parent-specific aspect of the ParentNode interface. Requires the master to be a ParentNode.
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 the master 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.

  - MixinParentNode
```
public MixinParentNode(ParentNode<N> master)
```
    Parameters:
    master - The master node that delegates to this instance.
  - MixinParentNode
```
public MixinParentNode(MixinParentNode<N> orig,
               ParentNode<N> newMaster,
               CopyState copyState)
```
    Copy constructor.
    
    Parameters:
    orig - The node to copy.
    newMaster - The master node for the copy.
- Method Detail
  - numChildren
```
public int numChildren()
```
    Gets the number of children.
    
    Returns:
    The number of children.
  - getChild
```
public 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
```
public 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
```
public List<N> getChildren()
```
    Gets the list of children. Note: The returned list is not 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
```
public void addChild(N child)
```
    Adds the given child.
    
    Parameters:
    child - The child to add.
  - addChild
```
public 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
```
public void removeChild(int index)
```
    Removes the child at the given index.
    
    Parameters:
    index - The index of the child to remove.
  - removeChild
```
public void removeChild(N child)
```
    Removes the given child.
    
    Parameters:
    child - The child to remove.
  - replaceChild
```
public 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
```
public 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
```
public void clearChildren()
```
    Clears the list of children.
  - addChildren
```
public void addChildren(List<? extends N> children)
```
    Adds the given children.
    
    Parameters:
    children - The children to add.
  - addChildren
```
public void addChildren(int index,
               List<? extends N> children)
```
    Adds the given children at the given index (shifting existing children if necessary).

    index - The index to add the children at.
    children - The children to add.
  - appendSourceStringForChildren
```
public void appendSourceStringForChildren(StringBuilder sb)
```
    Appends the source strings for all the children to the given StringBuilder.
    
    Parameters:
    sb - The StringBuilder to which to append the children's source strings.
  - toTreeString
```
public String toTreeString(int indent)
```
    Builds a string that visually shows the subtree rooted at this node (for debugging). Each line of the string will be indented by the given indentation amount. You should pass an indentation of 0 unless this method is being called as part of building a larger tree string.
    
    Parameters:
    indent - The indentation for each line of the tree string (usually pass 0).
    
    Returns:
    A string that visually shows the subtree rooted at this node.
