Class Combinations

java.lang.Object
io.nosqlbench.virtdata.library.basics.shared.from_long.to_string.Combinations
All Implemented Interfaces:
java.util.function.LongFunction<java.lang.String>
public class Combinations
extends java.lang.Object
implements java.util.function.LongFunction<java.lang.String>
Convert a numeric value into a code according to ASCII printable characters. This is useful for creating various encodings using different character ranges, etc. This mapper can map over the sequences of character ranges providing every unique combination and then wrapping around to the beginning again. It can convert between character bases with independent radix in each position. Each position in the final string takes its values from a position-specific character set, described by the shorthand in the examples below. The constructor will throw an error if the number of combinations exceeds that which can be represented in a long value. (This is a very high number).
