Classes
class	Halide::Param< T >
	A scalar parameter to a halide pipeline. More...

Namespaces
namespace	Halide
	This file defines the class FunctionDAG, which is our representation of a Halide pipeline, and contains methods to using Halide's bounds tools to query properties of it.

Macros
#define	HALIDE_HANDLE_TYPE_DISPATCH(CODE, BITS, TYPE)
#define	HALIDE_HANDLE_TYPE_DISPATCH(CODE, BITS, TYPE)

Functions
Expr	Halide::user_context_value ()
	Returns an Expr corresponding to the user context passed to the function (if any).
