The class representing the original values of the cells of databases.
The databases' cell translators for continuous variables.
virtual void setLowerBoundFromDouble(const double new_bound)=0
updates the lower bound of the domain of the variable
DBTranslator4ContinuousVariable(const std::vector< std::string > &missing_symbols, const bool fit_range=false)
default constructor without any initial variable
std::size_t domainSize() const final
returns std::numeric_limits<std::size_t>::max ()
const IContinuousVariable * variable() const final
returns the variable stored into the translator
HashTable< std::size_t, std::size_t > reorder() final
returns an empty mapping, indicating that old tanslations are equal to the newly reordered ones.
std::string translateBack(const DBTranslatedValue translated_val) const final
returns the original value for a given translation
bool needsReordering() const final
indicates that the translations should never be reordered
DBTranslatedValue missingValue() const final
returns the translation of a missing value
Set< std::string > missing_symbols_
the set of missing symbols
#define GUM_ERROR(type, msg)
