template<typename BasicJsonType, typename InputAdapterType>
class detail::lexer< BasicJsonType, InputAdapterType >

lexical analysis

This class organizes the lexical analysis during JSON deserialization.

Member Function Documentation

◆ get_token_string()

template<typename BasicJsonType , typename InputAdapterType >

std::string detail::lexer< BasicJsonType, InputAdapterType >::get_token_string ( ) const

inline

return the last read token (for errors only). Will never contain EOF (an arbitrary value that is not a valid char value, often -1), because 255 may legitimately occur. May contain NUL, which should be escaped.

◆ skip_bom()

template<typename BasicJsonType , typename InputAdapterType >

bool detail::lexer< BasicJsonType, InputAdapterType >::skip_bom ( )

inline

skip the UTF-8 byte order mark

Returns: true iff there is no BOM or the correct BOM has been skipped
