Description copied from interface: TestDataGenerator

Create a chunk for the given index using random for any desired entropy.

Specified by:

populateChunk in interface TestDataGenerator<Long,Long>

Overrides:

populateChunk in class AbstractReinterpretedGenerator<Long,Long>

Parameters:

toAdd - the index to add values for

random - the random number generator used for this test

Returns:

a chunk of primitives or boxed objects of type U

getType

public Class<Long> getType()

Returns:

the type of the chunk that we populate
