Class MapSizedHashed

java.lang.Object

io.nosqlbench.virtdata.library.basics.shared.from_long.to_collection.MapSizedHashed

All Implemented Interfaces:

LongFunction<Map<Object,Object>>

public class MapSizedHashed
extends Object
implements LongFunction<Map<Object,Object>>

Create a Map from a long input based on a set of provided key and value functions. Any duplicate entries produced by the key functions are elided. As a 'Sized' function, the first argument is a function which determines the size of the resulting map. Additional functions provided are used to generate the elements to add to the collection, as in the pair-wise mode of MapFunctions. If the size is larger than the number of provided functions, the last provided function is used repeatedly as needed. (respectively for key functions as well as value functions) As a 'Hashed' function, the input value is hashed again before being used by each key and value function.
