This class holds TagNode instances and helps build them into html when the time comes.

It is really just a simple array, with the addition of the #to_html method

Instance Method Details

#to_html(tags) ⇒ Object

This method is vulnerable to stack-level-too-deep scenarios where >=1,200 tags are being parsed.

But that scenario can be mitigated by splitting up the tags. bbtree = { :nodes => [900tags, 1000tags] }, the work for that bbtree can be split up into two passes, do the each node one at a time. I’m not coding that though, it’s pointless, just a thought though
