Constructor & Destructor Documentation

◆ Var() [1/2]

tvm::relay::Var::Var	(	String	name_hint,
		Type	type_annotation,
		Span	span = `Span()`
	)

inline

The constructor.

Parameters

name_hint	The name hint of a variable.
type_annotation	The type annotation of a variable.
span	The source span of the expression.

◆ Var() [2/2]

tvm::relay::Var::Var	(	Id	vid,
		Type	type_annotation,
		Span	span = `Span()`
	)

The constructor.

Parameters

vid	The unique id of a variable.
type_annotation	The type annotation of a variable.
span	The source span of the expression.

Member Function Documentation

◆ GenSym()

static Var tvm::relay::Var::GenSym	(	Type	type_annotation = `{}`,
		Span	span = `{}`
	)

static

Return a globally fresh name. Helps with debugging to follow the same variable between passes and sub-expressions.

TODO(mbs): Replace with name creation w.r.t. scopes once available as part of name gen overhaul.

◆ TVM_DEFINE_OBJECT_REF_COW_METHOD()

tvm::relay::Var::TVM_DEFINE_OBJECT_REF_COW_METHOD ( VarNode )

◆ TVM_DEFINE_OBJECT_REF_METHODS()

tvm::relay::Var::TVM_DEFINE_OBJECT_REF_METHODS	(	Var	,
		RelayExpr	,
		VarNode
	)
