public class FibonacciLongGenerator
extends RecurrenceRelationNumberGenerator<java.lang.Long>

Generates Fibonacci Numbers. It is defined recursively by

• F(0) = 1
• F(1) = 1
• F(n) = F(n-1) + F(n-2)

Constructor Detail

FibonacciLongGenerator

public FibonacciLongGenerator(java.lang.Long min,
                              java.lang.Long max,
                              boolean unique)

Method Detail

aN

protected java.lang.Long aN()

Description copied from class: RecurrenceRelationNumberGenerator

Must be implemented by child classes to implement the recurrence relation. It needs to use the RecurrenceRelationNumberGenerator.aN(int) method to retrieve the most recent calculated values.

Specified by:

aN in class RecurrenceRelationNumberGenerator<java.lang.Long>

a0

protected java.lang.Long a0(int n)

Description copied from class: RecurrenceRelationNumberGenerator

Must be implemented by child classes to return the seed values of the recurrence relation. These are the initial values which are defined as constants (a(0)..a(depth-1)).

Specified by:

a0 in class RecurrenceRelationNumberGenerator<java.lang.Long>

resetMembers

protected void resetMembers()

Overrides:

resetMembers in class RecurrenceRelationNumberGenerator<java.lang.Long>
