Member Function Documentation

◆ clear()

void mysql::gtid::Uuid::clear ( )

inline

Set to all zeros.

◆ copy_from()

void mysql::gtid::Uuid::copy_from ( const unsigned char * data )

inline

Copies the given 16-byte data to this UUID.

◆ copy_to()

void mysql::gtid::Uuid::copy_to ( unsigned char * data ) const

inline

Copies the given UUID object to this UUID.

◆ equals()

bool mysql::gtid::Uuid::equals ( const Uuid & other ) const

inline

Returns true if this UUID is equal the given UUID.

◆ is_valid()

bool mysql::gtid::Uuid::is_valid	(	const char *	string,
		size_t	len
	)

static

Returns true if parse() would succeed, but doesn't store the result.

Parameters

string	String that needs to be checked.
len	Length of that string.

Return values

true	valid string.
false	invalid string.

◆ operator<()

bool mysql::gtid::Uuid::operator< ( const Uuid & other ) const

inline

◆ parse() [1/2]

int mysql::gtid::Uuid::parse	(	const char *	in_string,
		size_t	len,
		const unsigned char *	out_binary_string
	)

static

Parses the UUID passed as argument in in_string and functions and writes the binary representation in out_binary_string.

Depends on UUID's read_section method and the constants for text length.

Parameters

[in]	in_string	String to be parsed.
[in]	len	Length of that string.
[out]	out_binary_string	String where the binary UUID will be stored

Return values

0	success.
>0	failure.

◆ parse() [2/2]

int mysql::gtid::Uuid::parse	(	const char *	string,
		size_t	len
	)

Stores the UUID represented by a string of the form XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX or XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX or {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX} in this object.

Parameters

string	String to be parsed and stored.
len	Length of that string.

Return values

0	success.
>0	failure.

◆ print()

void mysql::gtid::Uuid::print ( ) const

inline

◆ read_section()

bool mysql::gtid::Uuid::read_section	(	int	section_len,
		const char **	section_str,
		const unsigned char **	out_binary_str
	)

static

Helper method used to validate and parse one section of a uuid.

If the last parameter, out_binary_str, is NULL then the function will just validate the section.

Parameters

[in]	section_len	Length of the section to be parsed.
[in,out]	section_str	Pointer to a string containing the section. It will be updated during the execution as the string is parsed.
[out]	out_binary_str	String where the section will be stored in binary format. If null, the function will just validate the input string.

Return values

false	success.
true	failure.

◆ to_string() [1/3]

std::string mysql::gtid::Uuid::to_string ( ) const

inline

◆ to_string() [2/3]

size_t mysql::gtid::Uuid::to_string ( char * buf ) const

Generates a 36+1 character long representation of this UUID object in the given string buffer.

Return values

36	- the length of the resulting string.

◆ to_string() [3/3]

size_t mysql::gtid::Uuid::to_string	(	const unsigned char *	bytes_arg,
		char *	buf
	)

static

Convert the given binary buffer to a UUID.
