possibleOutputs()

std::vector<std::optional<Value> > mbgl::style::expression::Step::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.

serialize()

overridevirtual

Reimplemented from mbgl::style::expression::Expression.
