Member Function Documentation

add_collation()

int MY_CHARSET_LOADER::add_collation

(

CHARSET_INFO *

cs

)

Collation parser helper function (not overloadable).

Parameters

cs	New collation object to register in the collation library

Returns

MY_XML_OK on success, otherwise MY_XML_ERROR

mem_free()

virtual void MY_CHARSET_LOADER::mem_free ( void *  ptr )

inlinevirtual

Reimplemented in anonymous_namespace{charset.cc}::Mysys_charset_loader.

mem_malloc()

virtual void * MY_CHARSET_LOADER::mem_malloc ( size_t  size )

inlinevirtual

Reimplemented in anonymous_namespace{charset.cc}::Mysys_charset_loader.

once_alloc()

void * MY_CHARSET_LOADER::once_alloc ( size_t  size )

virtual

Allocate-and-forget version of malloc().

Reimplemented in anonymous_namespace{charset.cc}::Mysys_charset_loader.

operator=() [1/2]

MY_CHARSET_LOADER & MY_CHARSET_LOADER::operator= ( const MY_CHARSET_LOADER &&  )

delete

operator=() [2/2]

MY_CHARSET_LOADER & MY_CHARSET_LOADER::operator= ( const MY_CHARSET_LOADER &  )

delete

read_file()

virtual void * MY_CHARSET_LOADER::read_file ( const char *  path, size_t *  size  )

pure virtual

Loads a file by its OS path into collation parser/initializer.

Parameters

path	'\0'-terminated file path to load
size	Byte size of path

Returns

Pointer to file data on success, otherwise nullptr. This is a caller's responsibility to free this pointer with free().

Implemented in anonymous_namespace{collations_internal.cc}::Charset_loader, anonymous_namespace{charset.cc}::Mysys_charset_loader, and Loader.

reporter()

virtual void MY_CHARSET_LOADER::reporter ( enum loglevel  loglevel, unsigned  errcode,   ...  )

pure virtual

Intercepts error messages from collation parser/initializer.

Parameters

loglevel	ERROR_LEVEL or WARNING_LEVEL
errcode	See include/mysys_err.h

Implemented in anonymous_namespace{collations_internal.cc}::Charset_loader, and Loader.
