Macro Definition Documentation

CHECK_STATUS

#define CHECK_STATUS

(

s

)

Value:

  do {                     \
    int const status_ = s; \
    CHECK_EQ(0, status_);  \
  } while (0)

The argument to this macro is the invocation of a XPRS function that returns a status. If the function returns non-zero the macro aborts the program with an appropriate error message.

setParamIfPossible_MACRO

#define setParamIfPossible_MACRO	(		target_map,
			setter,
			converter )

Value:

  {                                                                      \
    auto matchingParamIter = (target_map).find(paramAndValuePair.first); \
    if (matchingParamIter != (target_map).end()) {                       \
      const auto convertedValue = converter(paramAndValuePair.second);   \
      VLOG(1) << "Setting parameter " << paramAndValuePair.first         \
              << " to value " << convertedValue << std::endl;            \
      setter(mLp, matchingParamIter->second, convertedValue);            \
      continue;                                                          \
    }                                                                    \

XPRS_NAN

#define XPRS_NAN   std::numeric_limits<double>::quiet_NaN()

In case we need to return a double but don't have a value for that we just return a NaN.
