Method Summary

Methods

Modifier and Type	Method and Description
byte[][]	generateKeys(int size) Generate B+Tree keys (no null, no duplicates, data are fully ordered based on unsigned byte[] comparison).
byte[][]	generateValues(int size) Generate B+Tree values (may include nulls).
boolean	isKeysGenerator() If the generator can generate B+Tree keys.
boolean	isValuesGenerator() If the generator can generate B+Tree values.

Method Detail

isKeysGenerator

boolean isKeysGenerator()

If the generator can generate B+Tree keys.

isValuesGenerator

boolean isValuesGenerator()

If the generator can generate B+Tree values.

generateKeys

byte[][] generateKeys(int size)

Generate B+Tree keys (no null, no duplicates, data are fully ordered based on unsigned byte[] comparison).

Parameters:

size - The #of keys.

Returns:

The keys.

Throws:

UnsupportedOperationException - if the generator can not generate B+Tree keys.

generateValues

byte[][] generateValues(int size)

Generate B+Tree values (may include nulls).

Parameters:

size - The #of values.

Returns:

The values.

Throws:

UnsupportedOperationException - if the generator can not generate B+Tree values.
