Function Documentation

find_by_id()

const CHARSET_INFO * mysql::collation::find_by_id

(

unsigned

id

)

Find collation by its number.

Parameters

id	Collation id (hardcoded in library sources or specified in Index.xml)

Returns

pointer to a collation object on success, nullptr if not found

find_by_name() [1/2]

const CHARSET_INFO * mysql::collation::find_by_name ( const char *  name )

inline

Find collation by its name.

Parameters

name	'\0'-terminated string of collation name (not normalized name is fine)

Returns

pointer to a collation object on success, nullptr if not found

find_by_name() [2/2]

const CHARSET_INFO * mysql::collation::find_by_name

(

const Name &

name

)

Find collation by its name.

Parameters

name	Collation name

Returns

pointer to a collation object on success, nullptr if not found

find_primary() [1/2]

const CHARSET_INFO * mysql::collation::find_primary ( const char *  cs_name )

inline

Find primary collation by its character set name.

Parameters

cs_name

'\0'-terminated string of character set name (not normalized name is fine)

Returns

pointer to a collation object on success, nullptr if not found

find_primary() [2/2]

const CHARSET_INFO * mysql::collation::find_primary

(

Name

cs_name

)

Find primary collation by its character set name.

Parameters

cs_name

Character set name

Returns

pointer to a collation object on success, nullptr if not found

initialize()

void mysql::collation::initialize	(	const char *	charset_dir = nullptr,
		MY_CHARSET_LOADER *	loader = nullptr
	)

Initialize character set/collation library.

Note

initialize() after shutdown() is UB (untested).

Parameters

charset_dir	Optional "/\0"-terminated path to the directory containing Index.xml
loader	Optional user-specified hooks to the character set/collation parser/initializer.

shutdown()

void mysql::collation::shutdown

(

)

Shutdown character set/collation library.

This call is mainly necessary in ASAN etc. builds.

Note

initialize() after shutdown() is UB (untested).
