nmodl::units::UnitTable Class Reference

Class that stores all the units, prefixes and names of base units used. More...

Detailed Description

Class that stores all the units, prefixes and names of base units used.

The UnitTable encapsulates all the containers that are needed to store all the Units defined. Those containers are:

• A table (hash map) that stores all the Units
• A hash map that stores all the Prefixes
• An array to store the base units names

The names and the design is based on the corresponding ones of MOD2C. The table is a hash map that uses as key the name of the Unit and as objects a shared_ptr to a Unit. This is needed as the parser passes to the UnitTable shared_ptrs, so that there is no need to allocate more space for the units or take care of the deallocation of the memory, which is done automatically by the smart pointer. A shared_ptr to a UnitTable is kept by the UnitDriver, to be able to populate the UnitTable by using multiple sources (files and strings). The UnitTable takes care of inserting Units, Prefixes and base units to the table calculating or the needed factors and dimensions.

Member Function Documentation

calc_denominator_dims()

void nmodl::units::UnitTable::calc_denominator_dims	(	const std::shared_ptr< Unit > &	unit,
		std::string	denominator_name
	)

Calculate unit's dimensions based on its denominator unit named denominator_name which is stored in the UnitTable's table.

Definition at line 192 of file units.cpp.

calc_nominator_dims()

void nmodl::units::UnitTable::calc_nominator_dims	(	const std::shared_ptr< Unit > &	unit,
		std::string	nominator_name
	)

get_base_unit_name()

const std::string& nmodl::units::UnitTable::get_base_unit_name ( int  id ) const

inlinenoexcept

Get base unit name based on the ID number of the dimension.

Definition at line 288 of file units.hpp.

get_unit()

const std::shared_ptr<Unit>& nmodl::units::UnitTable::get_unit ( const std::string &  unit_name ) const

inline

insert()

void nmodl::units::UnitTable::insert

(

const std::shared_ptr< Unit > &

unit
