Member Function Documentation

accept()

template<typename BasicJsonType >

bool nlohmann::detail::parser< BasicJsonType >::accept ( const bool  strict = true )

inline

public accept interface

Parameters

[in]

strict

whether to expect the last token to be EOF

Returns

whether the input is a proper JSON text

parse()

template<typename BasicJsonType >

void nlohmann::detail::parser< BasicJsonType >::parse ( const bool  strict, BasicJsonType &  result  )

inline

public parser interface

Parameters

[in]	strict	whether to expect the last token to be EOF
[in,out]	result	parsed JSON value

Exceptions

parse_error.101	in case of an unexpected token
parse_error.102	if to_unicode fails or surrogate error
parse_error.103	if to_unicode fails
