## Classes
struct | Halide::Internal::IRNode
| The abstract base classes for a node in the Halide IR. More...
struct | Halide::Internal::BaseStmtNode
| IR nodes are split into expressions and statements. More...
struct | Halide::Internal::BaseExprNode
| A base class for expression nodes. More...
struct | Halide::Internal::ExprNode< T >
| We use the "curiously recurring template pattern" to avoid duplicated code in the IR Nodes. More...
struct | Halide::Internal::StmtNode< T >
struct | Halide::Internal::IRHandle
| IR nodes are passed around opaque handles to them. More...
struct | Halide::Internal::IntImm
| Integer constants. More...
struct | Halide::Internal::UIntImm
| Unsigned integer constants. More...
struct | Halide::Internal::FloatImm
| Floating point constants. More...
struct | Halide::Internal::StringImm
| String constants. More...
struct | Halide::Expr
| A fragment of Halide syntax. More...
struct | Halide::ExprCompare
| This lets you use an Expr as a key in a map of the form map<Expr, Foo, ExprCompare> More...
struct | Halide::Range
| A single-dimensional span. More...
struct | Halide::Internal::Stmt
| A reference-counted handle to a statement node. More...
struct | Halide::Internal::Stmt::Compare
| This lets you use a Stmt as a key in a map of the form map<Stmt, Foo, Stmt::Compare> More...
