class DagInit

Declaration

class DagInit : public TypedInit, public Node, public TrailingObjects { /* full declaration omitted */ };

Description

(v a, b) - Represent a DAG tree value. DAG inits are required to have at least one value then a (possibly empty) list of arguments. Each argument can have a name associated with it.
