  - setReferenceIndex
```
public void setReferenceIndex(int referenceIndex)
```
    Sets a new reference_index for this ConstantMethodHandleInfo instance.
    If referenceIndex is less than or equal to 0, an IllegalArgumentException will be thrown.
    
    Parameters:
    
    referenceIndex - the new reference_index for this ConstantMethodHandleInfo instance
    
    Throws:
    
    java.lang.IllegalArgumentException - thrown if, and only if, referenceIndex is less than or equal to 0

    java.lang.NullPointerException - thrown if, and only if, document is null
  - newInstance
```
public static ConstantMethodHandleInfo newInstance(int referenceKind,
                                                   int referenceIndex)
```
    Returns a new ConstantMethodHandleInfo.
    If referenceKind is less than 0, or referenceIndex is less than or equal to 0, an IllegalArgumentException will be thrown.
    
    Parameters:
    
    referenceKind - the reference_kind for the new ConstantMethodHandleInfo instance
    
    referenceIndex - the reference_index for the new ConstantMethodHandleInfo instance
    
    Returns:
    
    a new ConstantMethodHandleInfo
    
    Throws:
    
    java.lang.IllegalArgumentException - thrown if, and only if, referenceKind is less than 0, or referenceIndex is less than or equal to 0
  - filter
```
public static java.util.List<ConstantMethodHandleInfo> filter(Node node)
```
    Returns a List with all ConstantMethodHandleInfos.
    All ConstantMethodHandleInfos are found by traversing node using a simple NodeHierarchicalVisitor implementation.
    If node is null, a NullPointerException will be thrown.
