C++ (Cpp) updateParametersFromXmlFile Examples

Example #1

File: Teuchos_XMLParameterListHelpers.cpp Project: 00liujj/trilinos

void Teuchos::updateParametersFromXmlFileAndBroadcast(
  const std::string &xmlFileName,
  const Ptr<ParameterList> &paramList,
  const Comm<int> &comm
  )
{
  if (comm.getSize()==1)
    updateParametersFromXmlFile(xmlFileName, paramList);
  else {
    if (comm.getRank()==0) {
      XMLParameterListReader xmlPLReader;
      xmlPLReader.setAllowsDuplicateSublists( false );
      FileInputSource xmlFile(xmlFileName);
      XMLObject xmlParams = xmlFile.getObject();
      std::string xmlString = toString(xmlParams);
      int strsize = xmlString.size();
      broadcast<int, int>(comm, 0, &strsize);
      broadcast<int, char>(comm, 0, strsize, &xmlString[0]);
      updateParametersFromXmlString(xmlString, paramList);
    }
    else {
      int strsize;
      broadcast<int, int>(comm, 0, &strsize);
      std::string xmlString;
      xmlString.resize(strsize);
      broadcast<int, char>(comm, 0, strsize, &xmlString[0]);
      updateParametersFromXmlString(xmlString, paramList);
    }
  }
}

Example #2

Teuchos::RCP<Teuchos::ParameterList>
Teuchos::getParametersFromXmlFile(const std::string &xmlFileName)
{
  RCP<ParameterList> pl = parameterList();
  updateParametersFromXmlFile(xmlFileName, pl.ptr());
  return pl;
}

Example #3

File: ParameterList_XMLDuplicateSublists.cpp Project: OpenModelica/OMCompiler-3rdParty

 TEUCHOS_UNIT_TEST( ParameterList, XMLDuplicatedSublists )
 {
   ParameterList pl;
   TEST_THROW( updateParametersFromXmlFile(filename, inOutArg(pl) ), DuplicateParameterSublist );
   TEST_THROW( getParametersFromXmlFile(filename), DuplicateParameterSublist );
   TEST_THROW( getParametersFromXmlFile(filename,null), DuplicateParameterSublist );
   //
   std::ifstream fin(filename.c_str());
   std::string xmlstring( (std::istreambuf_iterator<char>(fin)),
                           std::istreambuf_iterator<char>()      );
   TEST_THROW( updateParametersFromXmlString(xmlstring,inOutArg(pl) ), DuplicateParameterSublist );
   TEST_THROW( getParametersFromXmlString(xmlstring), DuplicateParameterSublist );
   TEST_THROW( getParametersFromXmlString(xmlstring,null), DuplicateParameterSublist );
 }

Example #4

File: ParameterList_UnitTest_Parallel.cpp Project: Blevs/Trilinos_tutorial

  std::string inputFile="input.xml";
  ParameterList A;
  ParameterList B;
  updateParametersFromXmlFile(inputFile, &A);
  updateParametersFromXmlFileAndBroadcast(inputFile, &B, *comm);
  out << "B = " << B;
  TEST_ASSERT( B.begin() != B.end() ); // Avoid false positive from empty lists

  // See if any process returned a failed (i.e. a non-zero local_failed)
  int local_failed = !(A == B);
  int global_failed = -1;
