public interface NormalizedKeyComputer
```
Normalized key computer for BinaryInMemorySortBuffer. For performance, subclasses are usually implemented through CodeGenerator.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`compareKey(MemorySegment segI, int offsetI, MemorySegment segJ, int offsetJ)`	Compares two normalized keys in respective `MemorySegment`.
`int`	`getNumKeyBytes()`	Get normalized keys bytes length.
`boolean`	`invertKey()`	Flag whether normalized key comparisons should be inverted key.
`boolean`	`isKeyFullyDetermines()`	whether the normalized key can fully determines the comparison.
`void`	`putKey(RowData record, MemorySegment target, int offset)`	Writes a normalized key for the given record into the target `MemorySegment`.
`void`	`swapKey(MemorySegment segI, int offsetI, MemorySegment segJ, int offsetJ)`	Swaps two normalized keys in respective `MemorySegment`.

void putKey(RowData record,
            MemorySegment target,
            int offset)

Writes a normalized key for the given record into the target MemorySegment.
