Тема: [C-target] Child-parent relationship
Кому: [email protected]
Hi!
Please correct me if I'm wrong. When constructing AST, child-parent
relationships are created by calling "freshenPACindixesAll" in function
"addChild"?
If so why "freshenPACindixesAll" is called only in one branch of
if-statement?
(antlr3basetree.c)
Why do we do selected action in function "setParent"? As a parent of "tree"
we set parent of "parent".
static void
setParent (pANTLR3_BASE_TREE tree, pANTLR3_BASE_TREE parent)
{
((pANTLR3_COMMON_TREE)(tree->super))->parent = parent == NULL ? NULL :
((pANTLR3_COMMON_TREE)(parent->super))->parent;
}
