Detailed Description

Implementation of token/tree streams that are used by the tree re-write rules to manipulate the tokens and trees produced by rules that are subject to rewrite directives.

Function Documentation

◆ _next()

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.

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.
