Detailed Description

template<class Iter_type>
class units_converter::Semantic_actions< Iter_type >

Class manages parsing of user defined field unit.

Class contains:

• object of type UnitData for storing user defined unit
• methods for create UnitData object
• methods managing exceptions, if user defined unit is not in correct format

For example, unit is defined in format: "MPa/rho/g_; rho = 990*kg*m^-3; g_ = 9.8*m*s^-2"

• this unit is composed of three parts separated by semicolons
• first part (MPa/rho/g) defines unit and allows operations multiplication, division and exponentiation of factors
• factor 'MPa' is predefined (MegaPascal), factors 'rho' and 'g_' must be defined in next parts
• first part is always obligatory
• following parts must be in format: '<shortcut> = (<multipicative_coeficient>*)<definition>'
• shotcut must correspond with user defined factor in first part
• multipicative_coeficient is optional
• definition allows operations multiplication, division and exponentiation of factors too
• symbol 'g_' must be defined in this format because 'g' is in conflict with gram

Member Function Documentation

template<class Iter_type>

void units_converter::Semantic_actions< Iter_type >::check_unit_data ( )

inline

Check unit_data_ object.

Method:

• marks factors that are defined as derived unit
• checks undefined factors of unit
• check conflicts in definitions of unit (same shortcut is defined by user and predefined in application)
• checks cyclic definition of unit
