Detailed Description

template<typename ResultT = ParseResult>
class mlir::AsmParser::KeywordSwitch< ResultT >

This class represents a StringSwitch like class that is useful for parsing expected keywords.

On construction, unless a non-empty keyword is provided, it invokes parseKeyword and processes each of the provided cases statements until a match is hit. The provided ResultT must be assignable from failure().

template<typename FnT>

std::enable_if_t<!std::is_convertible< FnT, ResultT >::value, KeywordSwitch & > mlir::AsmParser::KeywordSwitch< ResultT >::Case ( StringLiteral str, FnT && fn )

inline

Case that invokes the provided functor when true.

The parameters passed to the functor are the keyword, and the location of the keyword (in case any errors need to be emitted).
