public static final SoyErrorKind INVALID_DELEGATE_NAME
```
- Method Detail
  - getKind
```
public SoyNode.Kind getKind()
```
    Description copied from interface: SoyNode
    
    Returns this node's kind (corresponding to this node's specific type).
  - getDelCalleeName
```
public String getDelCalleeName()
```
    Returns the name of the delegate template being called.
  - getDelCalleeVariantExpr
```
@Nullable
public ExprRootNode getDelCalleeVariantExpr()
```

  - setParamsToRuntimeCheck
```
public void setParamsToRuntimeCheck(com.google.common.collect.ImmutableMap<TemplateDelegateNode,com.google.common.collect.ImmutableList<TemplateParam>> paramsToRuntimeCheck)
```
    Sets the template params that require runtime type checking for each possible delegate target.
  - getParamsToRuntimeCheck
```
public Collection<TemplateParam> getParamsToRuntimeCheck(TemplateNode callee)
```
    Description copied from class: CallNode
    
    Returns the subset of params of the callee that require runtime type checking when this node is being rendered.
    
    Overrides:
    
    getParamsToRuntimeCheck in class CallNode
  - allowsEmptyDefault
```
public boolean allowsEmptyDefault()
```
    Returns whether this delegate call defaults to empty string if there's no active impl.
  - getAllExprUnions
```
public List<ExprUnion> getAllExprUnions()
```
    Description copied from interface: SoyNode.ExprHolderNode
    
    Returns the list of expressions in this node.
    
    Specified by:
    
    getAllExprUnions in interface SoyNode.ExprHolderNode
    
    Overrides:
    
    getAllExprUnions in class CallNode
  - copy
```
public CallDelegateNode copy(CopyState copyState)
```
    Description copied from interface: Node
    Copies this node. The copy's parent pointer is set to null.
    All copy() overrides should follow this contract:
    - only leaf classes (in the class hierarchy) should have non-abstract clone methods
    - all leaf classes should be final
    - all leaf copy constructors should be private
    - all clone methods should look exactly like:
      {@literal @}Override public T copy(CopyState copyState) { return new T(this, copyState); }
    - all non-leaf copy constructors should be protected
    TODO(lukes): The usecases for a copy method are few and far between. Making the AST nodes immutable (or at least unmodifiable) would be preferable to maintaining our copy() methods.
    Don't clone nodes unless you know what you're doing. The Soy AST is not actually a tree (it contains back edges from variables to their definitions), and naively copying nodes can result in pointers into stale ASTs
    Returns:
    A clone of this code.
  - numChildren
```
public int numChildren()
```
    Description copied from interface: ParentNode
    
    Gets the number of children.
    
    Specified by:
    
    numChildren in interface ParentNode<N extends SoyNode>
    
    Returns:

public N getChild(int index)
```
    Description copied from interface: ParentNode
    
    Gets the child at the given index.
    
    Specified by:
    
    getChild in interface ParentNode<N extends SoyNode>
    
    Parameters:
    index - The index of the child to get.
    
    Returns:
    The child at the given index.
  - getChildIndex
```
public int getChildIndex(N child)
```
    Description copied from interface: ParentNode
    
    Finds the index of the given child.
    
    Specified by:

    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()
```
    Description copied from interface: ParentNode
    
    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.
    
    Specified by:
    
    getChildren in interface ParentNode<N extends SoyNode>
