Member Function Documentation

void QUICK_RANGE::make_max_endpoint	(	key_range *	kr,
		uint	prefix_length,
		key_part_map	keypart_map
	)		[inline]

Initalizes a key_range object for communication with storage engine.

This function facilitates communication with the Storage Engine API by translating the maximum endpoint of the interval represented by this QUICK_RANGE into an index range endpoint specifier for the engine.

Parameters:

Pointer	to an uninitialized key_range C struct.
prefix_length	The length of the search key prefix to be used for lookup.
keypart_map	A set (bitmap) of keyparts to be used.

void QUICK_RANGE::make_min_endpoint	(	key_range *	kr,
		uint	prefix_length,
		key_part_map	keypart_map
	)		[inline]

Initalizes a key_range object for communication with storage engine.

This function facilitates communication with the Storage Engine API by translating the minimum endpoint of the interval represented by this QUICK_RANGE into an index range endpoint specifier for the engine.

Parameters:

Pointer	to an uninitialized key_range C struct.
prefix_length	The length of the search key prefix to be used for lookup.
keypart_map	A set (bitmap) of keyparts to be used.
