We typedef the cbit_constructor_t is a constructor that use cbit create cexpr.
We typedef the cbit_constructor_map_t is a collection of constructors that use cbit create cexpr.
We typedef the value_constructor_t is a constructor that use value create cexpr.
We typedef the value_constructor_map_t is a collection of constructors that use value create cexpr.
We typedef the operator_constructor_t is a constructor that use operator create cexpr.
We typedef the operator_constructor_map_t is a collection of constructors that use operator create cexpr.
Fields¶
A collection of constructors that use cbit create cexpr.
A collection of constructors that use value create cexpr.

Methods¶
Get the Factory Instance object.
Returns:
Get cexpr by cbit.
Parameters:
| cbit | target cbit |
Returns:
CExpr*
Registration function This function can be used to register constructors that inherit subclasses of the CExpr class.
Parameters:

| cbit_constructor_t | constructor subclass constructor |
Get cexpr by value.
Parameters:
| cbit_size_t | target value |
Returns:
CExpr*

| CExpr* | right CExpr |
| int | target operator |
Returns:
CExpr*
Registration function This function can be used to register constructors that inherit subclasses of the CExpr class.
Parameters:
