[Trilinos-Users] [EXTERNAL] error reading xml ParameterList

[Bartlett, Roscoe A.]

There should be a single macro that does this.  My guess is that there are no tests for that particular parameter (but that is hard to believe given this is selecting the Belos solver type).

Hello

I think the correct line should be like this:

Teuchos::ValidatorXMLConverterDB::addConverter(
        Teuchos::DummyObjectGetter<
            Teuchos::StringToIntegralParameterEntryValidator<Thyra::EBelosSolverType>
            >::getDummyObject()
        ,
        Teuchos::rcp(
            new Teuchos::StringToIntegralValidatorXMLConverter<Thyra::EBelosSolverType>()
        )
    );

However, still the same error is thrown. Please check out the attach code.

P/S: I like Eric's stratimikos.xml. The reader works nicely with this. 8-)

This actually has to do with some code I wrote awhile back that helps serialize validators along with the parameter list when writing the parameterlist out to XML. By default Teuchos knows how to write out most of the validators to XML but for some (especially templated ones) it just doesn't know how to write them out. So you need to say to Teuchos: "Hey, I've got this validator that I want you to write out to XML whenever you serialize a parameterlist. Here's how to do it." Fortunately there's an easy way to do this for StringIntegralValidators. Just add the following code at the beggining of your program.

Teuchos::ValidatorXMLConverterDB::addConverter(DummyObjectGetter< StringIntegralValidator<Thyra::EBelosSolverType> >::getDummyObject(), rcp(new StringToIntegralValidatorXMLConverter<Thyra::EBelosSolverType>))


You'll wanna include the headers:
Teuchos_ValidatorXMLConverterDB.hpp
Teuchos_StandardValidatorXMLConverters.hpp
Teuchos_DummyObjectGetter.hpp


It might be good for us to even add a simple macro or function for adding new StringToIntegralValidator converters to the ValidatorXMLConverterDB since that's probably a common case.

This is an ugly file. Does someone know why the parameter list writer
spits out all of this extra stuff?

I've attached a version of the file to look at and use. Hopefully the
parameter list reader does a better job with it. I've removed all the
validator stuff, the RCP stuff and the docString stuff.
