Member Function Documentation

static Unit* units ( )

inlinestatic

Initialize the static Unit class.

Definition at line 29 of file units.h.

References Unit::s_u, Unit::Unit(), and Unit::units_mutex.

Referenced by Application::Application().

static void deleteUnit ( )

inlinestatic

Destroy the static Unit class.

Note this can't be done in a destructor.

Definition at line 41 of file units.h.

References Unit::s_u, and Unit::units_mutex.

doublereal actEnergyToSI ( const std::string & units_ )

inline

Return the multiplier required to convert an activation energy to SI units.

Parameters

units_ activation energy units

Definition at line 57 of file units.h.

References Unit::m_act_u, and Unit::toSI().

doublereal toSI ( const std::string & units_ )

inline

Return the multiplier required to convert a dimensional quantity with units specified by string 'units' to SI units.

The list of recognized units is stored as a stl map <string, doublereal>called m_u[] and m_act_u for activity coefficients. These maps are initialized with likely values.

Parameters

units_ String containing the units description
