| /** | ||
| * {@link TokenParser} for the 'lazyFor' node. | ||
| * | ||
| * This node allow lazy iteration over a {@link Stream}, without | ||
| * invoking extraneous terminal operations. In practice, this node | ||
| * is a wrapper for {@link Stream#forEach(java.util.function.Consumer)}. | ||
| * | ||
| * Unlike the regular 'for' node, no extra variables are defined, only | ||
| * the iteration variable, named in the token's usage. | ||
| * | ||
| * Accepted arguments are instance of {@link Stream}, {@link Collection} or arrays. | ||
| * | ||
| * Example: | ||
| * | ||
| * <pre> | ||
| * {% lazyFor item in itemStream %} | ||
| * {{item.name}} | ||
| * {% endLazyFor %} | ||
| * </pre> | ||
