Purpose
Defines the file extensions used by the storage engine.
Synopsis
virtual const char ** bas_ext
( |
); |
|
Description
This is the bas_ext method. It is called to
provide the MySQL server with a list of file extensions used by
the storage engine. The list returned is a null-terminated
string array.
By providing a list of extensions, storage engines can in many
cases omit the
delete_table()
function as the MySQL server will close all references to the
table and delete all files with the specified extension.
Parameters
There are no parameters for this function.
Return Values
-
Return value is a null-terminated string array of storage
engine extensions. The following is an example from the
CSV engine:
static const char *ha_tina_exts[] =
{
".CSV",
NullS
};
Usage
static const char *ha_tina_exts[] =
{
".CSV",
NullS
};
const char **ha_tina::bas_ext() const
{
return ha_tina_exts;
}
Default Implementation
static const char *ha_example_exts[] = {
NullS
};
const char **ha_example::bas_ext() const
{
return ha_example_exts;
}
