示例1: IsNextNonActionElementEOA

}示例2: EnsureAltIsSimpleNodeOrTree
/** Rules in tree grammar that use -> rewrites and are spitting out
* templates via output=template and then use rewrite=true must only
* use -> on alts that are simple nodes or trees or single rule refs
* that match either nodes or trees. The altAST is the ALT node
* for an ALT. Verify that its first child is simple. Must be either
* ( ALT ^( A B ) <end-of-alt> ) or ( ALT A <end-of-alt> ) or
* other element.
*
* Ignore predicates in front and labels.
