parseChar()

char parseChar	(	LINE_READER &	aReader,
		const char *	aCurrentToken,
		const char **	aNextToken = nullptr
	)

Parse a single ASCII character and updates the pointer at aOutput if it is not NULL.

Parameters

aReader	- The line reader used to generate exception throw information.
aCurrentToken	- A pointer the current position in a string.
aNextToken	- The pointer to a string pointer to copy the string pointer position when the parsing is complete.

Returns

A valid ASCII character.

Exceptions

IO_ERROR	on an unexpected end of line.

parseQuotedString()

void parseQuotedString	(	wxString &	aString,
		LINE_READER &	aReader,
		const char *	aCurrentToken,
		const char **	aNextToken = nullptr,
		bool	aCanBeEmpty = false
	)

Parse an quoted ASCII utf8 and updates the pointer at aOutput if it is not NULL.

The parsed string must be contained within a single line. There are no multi-line quoted strings in the legacy schematic file format.

Parameters

aString	- A reference to the parsed string.
aReader	- The line reader used to generate exception throw information.
aCurrentToken	- A pointer the current position in a string.
aNextToken	- The pointer to a string pointer to copy the string pointer position when the parsing is complete.
aCanBeEmpty	- True if the parsed string is optional. False if it is mandatory.

Exceptions

IO_ERROR	on an unexpected end of line.
PARSE_ERROR	if the aCanBeEmpty is false and no string was parsed.

		const char *	aCurrentToken,
		const char **	aNextToken = nullptr,
		bool	aCanBeEmpty = false
	)

Parse an unquoted utf8 string and updates the pointer at aOutput if it is not NULL.

The parsed string must be a continuous string with no white space.

Parameters

aString	- A reference to the parsed string.
aReader	- The line reader used to generate exception throw information.
aCurrentToken	- A pointer the current position in a string.
aNextToken	- The pointer to a string pointer to copy the string pointer position when the parsing is complete.
