Method make_class_group

code2flow/php.py:355–399

Given an AST for the subgroup (a class), generate that subgroup. In this function, we will also need to generate all of the nodes internal to the group. Specific to PHP, this can also be a namespace or class. :param tree ast: :param parent Group:

(tree, parent)
