Detailed Description

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() [1/2]

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.

get_token_string() [2/2]

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() [1/2]

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

skip_bom() [2/2]

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
