But in the meantime some further changes have been made and uploaded (around 23:30, Tuesday). The above should work. If it doesn't you can not have the most rectn version, and something is wrong.

Bernd, just implemented a combo box for temperature units. As we discussed yesterday, I check the available units with the allsymbols() method: YK ZK EK PK TK GK MK kK hK daK K dK cK mK muK nK pK fK aK zK yK oC oR oF well, maybe also a function, say 'commonsymbols()' that returns only oC,K,oF would be adequate.

Bernd, are you sure that you've uploaded the modified version? I've done a fresh checkout but could not find the Constructors. Also I've tried Concentration cc(0.5,"molL^-1"); to the test program and it did not compile: e.h: In constructor `Quantities::Variable<Quantities::Quantity<GT, Loki::Typelist<U, UTail>, DU, DT>, U>::Variable(DT, const NU&) [with NU =3D char[8], G= T =3D Quantities::ConcentrationGroup, Head =3D Quantities::ConcentrationUnits::MolePerLitre, Tail =3D Loki::Typelist<Quantities::ConcentrationUnits::MilliMolePerLitre, Loki::NullType>, DU =3D Quantities::ConcentrationUnits::MolePerLitre, = U =3D Quantities::ConcentrationUnits::MolePerLitre, DT =3D double]': modelParametersDialog.cpp:339: instantiated from here /home/kl/software/src/quantity/Quantities/Quantity/Variable.h:125: no method ` Units::UnitError<true>::Standard' ??Kai --=20 http://echempp.sourceforge.net Kai Ludwig Institut f=FCr Organische Chemie Auf der Morgenstelle 18 72076 T=FCbingen Tel.: 07071/29-73049 Mail: kai...@un... |

I'm sending this to quantity-devel only, since this is technical stuff. The problem Kai detected is difficult to solve. In fact, regrettably, I hadn't even really tested the constructor Variable (value, unit) in the situation where unit is generated by lookup of the unit string. the lookup function AllUnits::unit (std::string) returns a pointer the the base class of the unit found, i.e. TimeUnit if a Minute is found. That's ok if we just need one of the virtual functions of this object, e.g. standard () (see, method read_value in Variable.h). If we want to use the constructor above, it relies on the correctness of the type of the unit object passed, since it does check (at compile time) whether this type occurs in the list of units of the quantity in question. Of course, the base class is not in the list!! On the other hand, I think, we can not know at compile time the string of the unit symbol anyway, can we? It might be supplied by the user through a GUI for example. Thus, there is no way to compile time check the correctness of the unit object anyway. I suggest to have another constructor Variable (value, std::string) which generates the corresponding unit object at run time through AllUnits::unit (), does the necessary computation and the throws away this object. Note, that a statement like Time t (1.0, Minute ()) generates a Time object which stores its value in seconds, the Minute just indicates that the value 1.0 is to be interpreted as a minute! An object which stores in minutes would be MinuteTime! This would also solve the problem of having the caller require to delete the generated object. It could be done hidden inside the constructor. Maybe AllUnits::unit should then be made private. Would that help?

Kai found earlier a problem with gcc 3.2 compilation of Quantities, and suggested that some compiler flags were the reason. Yes, indeed that's true. In particular, the -W flag produced many warnings, as regards missing initializers, unused variables of function calls, and non-initialized dummy variables. All these things have been corrected in the most recent cvs version of the code. I have also changed all compiler flags to include the -W flag.

The AllUnits template now contains a new member function `allsymbols ()'. This returns a std::vector<std::string> of the unit symbols which are listed for a certain quantity. Could be used as std::vector<std::string> timeunit_symbols Time::AllUnits::allsymbols (); This example is included in QuantityTest.cc. Please check under realistic conditions ...

//! replace the element at position index
template<template<class, class> class Q1, class GT1, class Head1,
class Tail1, class DU1, class U1, class DT1>
void replace (const int index, const Q1<Quantity<GT1,
Typelist<Head1, Tail1>, DU1, DT1>, U1> &new_quantity)
{
if (index >=3D 0 && index < length ())
{
values[index] =3D
Unit::Reverse(CheckAgainstAllUnits<typename Q1<Quantity<GT1,
Typelist<Head1, Tail1>, DU1, DT1>, U1>::Unit,
typename TL::Append<Typelist<Head, Tail>,
NonPrefixable<typename Q1<Quantity<GT1,

GenericUnit, DT>
>::Result >::RET::Standard
(new_quantity.raw_value()));
}
else
{throw QuantityVectorOutOfBounds();}
}

Kai, in the PhysicalQuantitiesTest program you could use PureNumber ratio; cout << ratio (c1/cref) << std::endl; to get rid of the annoying (unknown unit). Alternatively, you can say: Fraction ratio = c1/cref; cout << ratio << std::endl; Bernd -- ======================================================================= Bernd Speiser Institut f"ur Organische Chemie Auf der Morgenstelle 18 D-72076 T"ubingen Germany phone: +49-7071-2976205 (office) +49-7071-2976242 (laboratory) fax: +49-7071-295518 e-mail: ber...@un...
