Detailed Description

GlobalVarSupply can be used to generate unique GlobalVars.

Constructor & Destructor Documentation

GlobalVarSupplyNode() [1/2]

tvm::GlobalVarSupplyNode::GlobalVarSupplyNode ( )

inline

Empty constructor. Will use an empty NameSupply.

GlobalVarSupplyNode() [2/2]

tvm::GlobalVarSupplyNode::GlobalVarSupplyNode ( NameSupply  name_supply, std::unordered_map< std::string, GlobalVar >  name_to_var_map = {}  )

explicit

Constructor.

Parameters

name_supply	The NameSupply to use for generating the names of fresh GlobalVars.
name_to_var_map	An optional map.

Member Function Documentation

FreshGlobal()

GlobalVar tvm::GlobalVarSupplyNode::FreshGlobal	(	String	name,
		bool	add_prefix = true
	)

Generates a unique GlobalVar from this supply.

Parameters

name	The name from which the name of the GlobalVar is derived.
add_prefix	If set to true, then the prefix of the contained NameSupply will be prepended to the name.

Returns

A unique GlobalVar.

ReserveGlobalVar()

void tvm::GlobalVarSupplyNode::ReserveGlobalVar	(	const GlobalVar &	var,
		bool	allow_conflict = false
	)

Reserves an existing GlobalVar with this supply.

Parameters

var	The GlobalVar to be registered.
allow_conflict	Allow conflict with other GlobalVars that have the same name.

TVM_DECLARE_FINAL_OBJECT_INFO()

tvm::GlobalVarSupplyNode::TVM_DECLARE_FINAL_OBJECT_INFO	(	GlobalVarSupplyNode	,
		Object
	)

UniqueGlobalFor()

GlobalVar tvm::GlobalVarSupplyNode::UniqueGlobalFor	(	const String &	name,
		bool	add_prefix = true
	)

Looks up for a GlobalVar with the given name in this supply. If no entry is found, creates one, places it in the cache and returns it.

Parameters

name	The name of the GlobalVar to search for.
add_prefix	If set to true, the prefix of the contained NameSupply will be prepended to the name before performing the search.

Returns

A cached GlobalVar.

VisitAttrs()

void tvm::GlobalVarSupplyNode::VisitAttrs ( AttrVisitor *  v )

inline
