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().

Member Function Documentation

◆ Case() [1/2]

template<typename ResultT = ParseResult>
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).

◆ Case() [2/2]

template<typename ResultT = ParseResult>
KeywordSwitch& mlir::AsmParser::KeywordSwitch< ResultT >::Case ( StringLiteral  str,
ResultT  value 
)
inline

Case that uses the provided value when true.

◆ Default() [2/2]

template<typename ResultT = ParseResult>
KeywordSwitch& mlir::AsmParser::KeywordSwitch< ResultT >::Default ( ResultT  value)
inline

◆ hasValue()

template<typename ResultT = ParseResult>
bool mlir::AsmParser::KeywordSwitch< ResultT >::hasValue ( ) const
inline

Returns true if this switch has a value yet.

◆ operator ResultT()

template<typename ResultT = ParseResult>
mlir::AsmParser::KeywordSwitch< ResultT >::operator ResultT ( )
inline

Return the result of the switch.
