Detailed Description

IR nodes are passed around opaque handles to them.

This is a base class for those handles. It manages the reference count, and dispatches visitors.

Member Function Documentation

accept()

void Halide::Internal::IRHandle::accept ( IRVisitor * v ) const

inline

Dispatch to the correct visitor method for this node.

E.g. if this node is actually an Add node, then this will call IRVisitor::visit(const Add *)

as()

template<typename T >

const T * Halide::Internal::IRHandle::as ( ) const

inline

Downcast this ir node to its actual type (e.g.

Add, or Select). This returns nullptr if the node is not of the requested type. Example usage:

if (const Add *add = node->as<Add>()) { // This is an add node }
