code: protected Object getValue(Object value, ComparisonType type) {
          return type == ComparisonType.NODE_TYPE ? nodeType((Short) value) : value;
      }
docs: May alter the display of a comparison value for {@link #getShortString} based on the comparison type.
  
  <p>This implementation returns {@code value} unless it is a comparison of node types in which case the numeric
  value (one of the constants defined in the {@link Node} class) is mapped to a more useful String.</p>
  
  @param value the value to display
  @param type the comparison type
  @return the display value
