Parameters:

object - the object or collection to print

color - the color to print the object with

bold - whether to display it in bold text private void print(Value value, Color color, boolean bold) { CollectionValue collectionValue = value.isCollectionValue(); if (collectionValue != null) { for (Value elementValue : collectionValue) { append(String.valueOf(elementValue), color, bold); } } else { append(String.valueOf(value), color, bold); } /* Collection toPrint; if (object == null) { toPrint = Collections.EMPTY_SET; } else if (object instanceof Collection) { toPrint = (Collection) object; } else if (object.getClass().isArray()) { toPrint = Arrays.asList((Object[]) object); } else { toPrint = Collections.singleton(object); } for (Iterator iter = toPrint.iterator(); iter.hasNext();) { append(toString(iter.next()), color, bold); } * / // append(String.valueOf(object), color, bold); scrollText(); }
