◆ get_codepoint()

template<typename BasicJsonType , typename InputAdapterType >

int nlohmann::detail::lexer< BasicJsonType, InputAdapterType >::get_codepoint ( )

inlineprivate

get codepoint from 4 hex characters following \u

For input "\u c1 c2 c3 c4" the codepoint is: (c1 * 0x1000) + (c2 * 0x0100) + (c3 * 0x0010) + c4 = (c1 << 12) + (c2 << 8) + (c3 << 4) + (c4 << 0)

Furthermore, the possible characters '0'..'9', 'A'..'F', and 'a'..'f' must be converted to the integers 0x0..0x9, 0xA..0xF, 0xA..0xF, resp. The conversion is done by subtracting the offset (0x30, 0x37, and 0x57) between the ASCII value of the character and the desired integer value.

Returns: codepoint (0x0000..0xFFFF) or -1 in case of an error (e.g. EOF or non-hex character)

check if the next byte(s) are inside a given range

Adds the current byte and, for each passed range, reads a new byte and checks if it is inside the range. If a violation was detected, set up an error message and return false. Otherwise, return true.

Parameters

[in] ranges list of integers; interpreted as list of pairs of inclusive lower and upper bound, respectively

Precondition: The passed list ranges must have 2, 4, or 6 elements; that is, 1, 2, or 3 pairs. This precondition is enforced by an assertion.

Returns: true if and only if no range violation was detected

token_type nlohmann::detail::lexer< BasicJsonType, InputAdapterType >::scan_number ( )

inlineprivate

scan a number literal

This function scans a string according to Sect. 6 of RFC 7159.

The function is realized with a deterministic finite state machine derived from the grammar described in RFC 7159. Starting in state "init", the input is read and used to determined the next state. Only state "done" accepts the number. State "error" is a trap state to model errors. In the table below, "anything" means any character but the ones listed before.

state	0	1-9	e E	+	-	.	anything
init	zero	any1	[error]	[error]	minus	[error]	[error]
minus	zero	any1	[error]	[error]	[error]	[error]	[error]
zero	done	done	exponent	done	done	decimal1	done
any1	any1	any1	exponent	done	done	decimal1	done
decimal1	decimal2	decimal2	[error]	[error]	[error]	[error]	[error]
decimal2	decimal2	decimal2	exponent	done	done	done	done
exponent	any2	any2	[error]	sign	sign	[error]	[error]
sign	any2	any2	[error]	[error]	[error]	[error]	[error]
any2	any2	any2	done	done	done	done	done

The state machine is realized with one label per state (prefixed with "scan_number_") and goto statements between them. The state machine contains cycles, but any cycle can be left when EOF is read. Therefore, the function is guaranteed to terminate.

During scanning, the read bytes are stored in token_buffer. This string is then converted to a signed integer, an unsigned integer, or a floating-point number.

Returns: token_type::value_unsigned, token_type::value_integer, or token_type::value_float if number could be successfully scanned, token_type::parse_error otherwise

Note: The scanner is independent of the current locale. Internally, the locale's decimal point is used instead of . to work with the locale-dependent converters.

◆ scan_string()

template<typename BasicJsonType , typename InputAdapterType >

token_type nlohmann::detail::lexer< BasicJsonType, InputAdapterType >::scan_string ( )

inlineprivate

scan a string literal

This function scans a string according to Sect. 7 of RFC 7159. While scanning, bytes are escaped and copied into buffer token_buffer. Then the function returns successfully, token_buffer is not null-terminated (as it may contain \0 bytes), and token_buffer.size() is the number of bytes in the string.

Returns: token_type::value_string if string could be successfully scanned, token_type::parse_error otherwise

Note: In case of errors, variable error_message contains a textual description.
