Typedefs

typedef std::function<CExpr*(CBit*)> cbit_constructor_t

We typedef the cbit_constructor_t is a constructor that use cbit create cexpr.

typedef std::map<std::string, cbit_constructor_t> cbit_constructor_map_t

We typedef the cbit_constructor_map_t is a collection of constructors that use cbit create cexpr.

typedef std::function<CExpr*(cbit_size_t)> value_constructor_t

We typedef the value_constructor_t is a constructor that use value create cexpr.

typedef std::map<std::string, value_constructor_t> value_constructor_map_t

We typedef the value_constructor_map_t is a collection of constructors that use value create cexpr.

typedef std::function<CExpr*(CExpr*, CExpr*, int)> operator_constructor_t

We typedef the operator_constructor_t is a constructor that use operator create cexpr.

typedef std::map<std::string, operator_constructor_t> operator_constructor_map_t

We typedef the operator_constructor_map_t is a collection of constructors that use operator create cexpr.

Fields

Methods

static CExprFactory& GetFactoryInstance()

Get the Factory Instance object.

Returns:

CExprFactory &

CExpr* GetCExprByCBit(CBit* cbit)

Get cexpr by cbit.

Parameters:

cbit	target cbit

Returns:

CExpr*

void registerclass_CBit_(std::string& name, cbit_constructor_t constructor)

Registration function This function can be used to register constructors that inherit subclasses of the CExpr class.

Parameters:

std::string	name subclass name
cbit_constructor_t	constructor subclass constructor

CExpr* GetCExprByValue(cbit_size_t value)

Get cexpr by value.

Parameters:

cbit_size_t

target value

Returns:

CExpr*

void registerclass_Value_(std::string&, value_constructor_t)

Registration function This function can be used to register constructors that inherit subclasses of the CExpr class.

Parameters:

std::string	subclass name
value_constructor_t	subclass constructor

CExpr* GetCExprByOperation(CExpr* left_cexpr, CExpr* right_cexpr, int operat)

Get cexpr by Operation.

Parameters:

CExpr*	left CExpr
CExpr*	right CExpr
int	target operator

Returns:

CExpr*

void registerclass_operator_ (std::string&, operator_constructor_t)

Registration function This function can be used to register constructors that inherit subclasses of the CExpr class.

Parameters:

std::string	subclass name
operator_constructor_t	subclass constructor
