Detailed Description

template<typename It>
class donut::json::Lexer< It >

Lexical analyzer for scanning and tokenizing input in the JSON5 format.

Template Parameters

It	iterator type of the underlying input source. Must be an input iterator.

Constructor & Destructor Documentation

Lexer()

template<typename It >

donut::json::Lexer< It >::Lexer ( unicode::UTF8Iterator< It >  it, unicode::UTF8Sentinel  end, const SourceLocation &  source  )

inline

Construct a lexer with a Unicode iterator pair as input.

Parameters

it	iterator to the beginning of the JSON input to scan.
end	sentinel that marks the end of the JSON input to scan.
source	initial source location corresponding to the current position of the iterator.

Warning

The iterator pair [it, end) must form a valid forward range.

Member Function Documentation

scan()

template<typename It >

Token donut::json::Lexer< It >::scan ( )

inline

Scan and consume the next token from the input.

This advances the internal state of the lexer.
