Instance Method Detail

def children : Array(ParseTree) #
Description copied from class Arborist::ParseTree

children returns the list of all actual/literal child ParseTree nodes in parse tree structure, rather than skipping some, as with #terms Another way of thinking about this is #children returns concrete children, #terms returns logical children.
