| forward (&$i, &$current) | |
| Iterator function, which starts with the next token and continues until you reach the end of the input tokens. More... | |
| forwardUntilEndToken (&$i, &$current, &$nesting) | |
| Similar to _forward, but accepts a third parameter $nesting (which should be initialized at 0) and stops when we hit the end tag for the node $this->inputIndex starts in. More... | |
| backward (&$i, &$current) | |
| Iterator function, starts with the previous token and continues until you reach the beginning of input tokens. More... | |
