Class HashedFloatVectors

java.lang.Object

io.nosqlbench.virtdata.lib.vectors.primitive.HashedFloatVectors

All Implemented Interfaces:

LongFunction<float[]>

public class HashedFloatVectors
extends Object
implements LongFunction<float[]>

Construct an arbitrarily large float vector with hashes. The initial value is assumed to be non-hashed, and is thus hashed on input to ensure that inputs are non-contiguous. Once the starting value is hashed, the sequence of long values is walked and each value added to the vector is hashed from the values in that sequence.

HashedFloatVectors

public HashedFloatVectors(Object sizer,
 Object valueFunc)

Build a double[] generator with a given size value or size function, and the given long->double function.

Parameters:

sizer - Either a numeric type which sets a fixed dimension, or a long->int function to derive it uniquely for each input

valueFunc - A long->double function
