示例1:
/** Transform ^(nil x) to x
*/
static pANTLR3_BASE_TREE
rulePostProcessing (pANTLR3_BASE_TREE_ADAPTOR adaptor, pANTLR3_BASE_TREE root)
{
pANTLR3_BASE_TREE saveRoot;
// Keep track of the root we are given. If it is a nilNode, then we
// can reuse it rather than orphaning it!
//
saveRoot = root;
if (root != NULL && root->isNilNode(root))
{
if (root->getChildCount(root) == 0)
{
root = NULL;
}
else if (root->getChildCount(root) == 1)
{
root = (pANTLR3_BASE_TREE)root->getChild(root, 0);
root->setParent(root, NULL);
root->setChildIndex(root, -1);
// The root we were given was a nil node, wiht one child, which means it has
// been abandoned and would be lost in the node factory. However
// nodes can be flagged as resuable to prevent this terrible waste
//
saveRoot->reuse(saveRoot);
}
}
return root;
