- Constructor Detail
  - ByteArrayAnnotatedOutput
```
public ByteArrayAnnotatedOutput(byte[] data)
```
    Constructs an instance with a fixed maximum size. Note that the given array is the only one that will be used to store data. In particular, no reallocation will occur in order to expand the capacity of the resulting instance. Also, the constructed instance does not keep annotations by default.
    
    Parameters:
    
    data - non-null; data array to use for output
  - ByteArrayAnnotatedOutput
```
public ByteArrayAnnotatedOutput()
```
    Constructs a "stretchy" instance. The underlying array may be reallocated. The constructed instance does not keep annotations by default.
  - ByteArrayAnnotatedOutput
```
public ByteArrayAnnotatedOutput(int size)
```

    isVerbose in interface AnnotatedOutput
    
    Returns:
    
    true iff annotations are to be verbose
  - annotate
```
public void annotate(java.lang.String msg)
```
    Add an annotation for the subsequent output. Any previously open annotation will be closed by this call, and the new annotation marks all subsequent output until another annotation call.

    annotate in interface AnnotatedOutput
    
    Parameters:
    
    msg - non-null; the annotation message

```
    Add an annotation for a specified amount of subsequent output. Any previously open annotation will be closed by this call. If there is already pending annotation from one or more previous calls to this method, the new call "consumes" output after all the output covered by the previous calls.
    
    Specified by:
    
    annotate in interface AnnotatedOutput

    amt - >= 0; the amount of output for this annotation to cover
    
    msg - non-null; the annotation message
  - endAnnotation

public void endAnnotation()
```
    End the most recent annotation. Subsequent output will be unannotated, until the next call to AnnotatedOutput.annotate(java.lang.String).
    
    Specified by:
    
    endAnnotation in interface AnnotatedOutput
  - getAnnotationWidth
```
public int getAnnotationWidth()
```
    Get the maximum width of the annotated output. This is advisory: Implementations of this interface are encouraged to deal with too-wide output, but annotaters are encouraged to attempt to avoid exceeding the indicated width.
    
    Specified by:
    
    getAnnotationWidth in interface AnnotatedOutput
    
    Returns:
    
    >= 1; the maximum width
  - enableAnnotations
```
public void enableAnnotations(int annotationWidth,
                              boolean verbose)
```
    Indicates that this instance should keep annotations. This method may be called only once per instance, and only before any data has been written to the it.
    
    Parameters:
    
    annotationWidth - >= 40; the desired maximum annotation width
    
    verbose - whether or not to indicate verbose annotations
  - finishAnnotating
```
public void finishAnnotating()
```
    Finishes up annotation processing. This closes off any open annotations and removes annotations that don't refer to written data.
  - writeAnnotationsTo
```
public void writeAnnotationsTo(java.io.Writer out)
                        throws java.io.IOException
```
    Writes the annotated content of this instance to the given writer.

    out - non-null; where to write to
    
    Throws:
    
    java.io.IOException
