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.

Definition at line 120 of file opt_range.h.

void QUICK_RANGE::make_max_endpoint ( key_range *  kr )

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.

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.
