Function Documentation
static void * _next (pANTLR3_REWRITE_RULE_ELEMENT_STREAM stream) [static]
Do the work of getting the next element, making sure that it's a tree node or subtree. Deal with the optimization of single- element list versus list of size > 1. Throw an exception (or something similar) if the stream is empty or we're out of elements and size>1. You can override in a 'subclass' if necessary.

static pANTLR3_BASE_TREE nextNode (pANTLR3_REWRITE_RULE_ELEMENT_STREAM stream) [static]
Treat next element as a single node even if it's a subtree. This is used instead of next() when the result has to be a tree root node. Also prevents us from duplicating recently-added children; e.g., ^(type ID)+ adds ID to type and then 2nd iteration must dup the type node, but ID has been added.
Referencing to a rule result twice is ok; dup entire tree as we can't be adding trees; e.g., expr expr.
