transformChildren

public IrNode transformChildren(UnaryOperator<IrNode> op)

Description copied from class: IrNode

Function-style child transformation hook used by the transform pipeline to descend into nested structures. Contract: - Leaf nodes return this unchanged. - Container nodes return a new instance with their immediate children transformed using the provided operator. - Implementations must not mutate this or its existing children.

Overrides:

getVars

public Set<Var> getVars()

Description copied from class: IrNode

Collect variables referenced by this node and all of its children (if any). Default implementation returns an empty set; container and triple-like nodes override to include their own Vars and recurse into child nodes.
