public int actualSize(int position,
                      int length)
```
    Returns:
    
    the actual size of the AST node at position, including comments.
  - actualStartColumn
```
public Integer actualStartColumn(int position)
```
    Returns:
    
    the start column of the token at position, including leading comments.
  - addAll
```
public final void addAll(List<Op> ops)
```
    Add a list of Ops.
  - getInput
```
public final Input getInput()
```
    Get the OpsBuilder's Input.
  - depth
```
public int depth()
```
    Returns the number of unclosed open ops in the input stream.
  - checkClosed
```
public void checkClosed(int previous)
```
    Checks that all open ops in the op stream have matching close ops.
    
    Throws:
    
    FormattingError - if any ops were unclosed
  - diagnostic
```
public FormatterDiagnostic diagnostic(String message)
```
    Create a FormatterDiagnostic at the current position.
  - sync
```
public final void sync(int inputPosition)
```
    Sync to position in the input. If we've skipped outputting any tokens that were present in the input tokens, output them here and optionally complain.
    
    Parameters:
    
    inputPosition - the 0-based input position
  - drain
```
public final void drain()
```
    Output any remaining tokens from the input stream (e.g. terminal whitespace).
  - open
```
public final void open(Indent plusIndent)
```
    Open a new level by emitting an OpenOp.
    
    Parameters:
    
    plusIndent - the extra indent for the new level
  - close
```
public final void close()
```
    Close the current level, by emitting a CloseOp.

```
    Return the text of the next Input.Token, or absent if there is none.
  - guessToken
```
public final void guessToken(String token)
```
    Emit an optional token iff it exists on the input. This is used to emit tokens whose existence has been lost in the AST.
