All Implemented Interfaces:

```
public final class ExprRootNode
extends AbstractParentExprNode
```
Dummy node that serves as the root of an expression tree so that the tree can be arbitrarily changed without needing to change the reference to the tree.
Important: Do not use outside of Soy code (treat as superpackage-private).
This node should always have exactly one child.

- Constructor Detail
  - ExprRootNode
```
public ExprRootNode(ExprNode child)
```
    Creates a new instance with the given node as the child.
    
    Parameters:
    child - The child to add to the new node.
- Method Detail
  - unwrap
```
public static List<ExprNode> unwrap(Iterable<ExprRootNode> exprs)
```
  - wrap
```
public static List<ExprRootNode> wrap(Iterable<? extends ExprNode> exprs)
```
  - getKind
```
public ExprNode.Kind getKind()
```
    Description copied from interface: ExprNode
    
    Gets this node's kind (corresponding to this node's specific type).
    
    Returns:
    This node's kind (corresponding to this node's specific type).
  - getRoot
```
public ExprNode getRoot()
```
  - getChild
```
public ExprNode getChild(int index)
```
    Description copied from interface: ParentNode
    
    Gets the child at the given index.
    
    Specified by:
    
    getChild in interface ParentNode<ExprNode>
    
    Overrides:
    
    getChild in class AbstractParentExprNode
    
    Parameters:
    index - The index of the child to get.
    
    Returns:
    The child at the given index.
  - toSourceString
```
public String toSourceString()
```
    Description copied from interface: Node
    
    Builds a Soy source string that could be the source for this node. Note that this is not the actual original source string, but a (SORT OF, NOT QUITE) canonical equivalent. Note: Some nodes do not have a direct mapping to Soy source (such as nodes created during some optimization passes). Thus this method may not always be supported.
    
    Returns:
    A Soy string that could be the source for this node.
  - copy
```
public ExprRootNode copy(CopyState copyState)
```
    Description copied from interface: ExprNode
    
    See Node.copy(CopyState) for a description of the copy contract.
    
    Returns:
    A clone of this code.
