Member Function Documentation

eachChild()

void mbgl::style::expression::BasicComparison::eachChild ( const std::function< void(const Expression &)> &  visit ) const

overridevirtual

Implements mbgl::style::expression::Expression.

evaluate()

EvaluationResult mbgl::style::expression::BasicComparison::evaluate ( const EvaluationContext &  ) const

overridevirtual

Implements mbgl::style::expression::Expression.

getOperator()

std::string mbgl::style::expression::BasicComparison::getOperator ( ) const

overridevirtual

Implements mbgl::style::expression::Expression.

operator==()

bool mbgl::style::expression::BasicComparison::operator== ( const Expression &  ) const

overridevirtual

Implements mbgl::style::expression::Expression.

possibleOutputs()

std::vector<std::optional<Value> > mbgl::style::expression::BasicComparison::possibleOutputs ( ) const

overridevirtual

Statically analyze the expression, attempting to enumerate possible outputs. Returns an array of values plus the sentinel null optional value, used to indicate that the complete set of outputs is statically undecidable.

Implements mbgl::style::expression::Expression.
