Class AdjustableNumberGenerator<T extends java.lang.Number>

  • Type Parameters:
    T - The type of number generated by this number generator.
    All Implemented Interfaces:
    NumberGenerator<T>
    public class AdjustableNumberGenerator<T extends java.lang.Number>
extends java.lang.Object
implements NumberGenerator<T>
    Implementation of NumberGenerator that works similarly to ConstantGenerator but allows the returned value to be changed after instantiation. The most useful application of this type of number generator is to permit runtime re-configuration of objects that rely on NumberGenerators for their parameters. This can be achieved by creating UI components (e.g. sliders and spinners) that invoke setValue(Number) when their state changes.
