Class SizedObjectFactory<T extends SizedObject>

  • public abstract class SizedObjectFactory<T extends SizedObject>
extends java.lang.Object

    This class holds factories to produces objects of variable size/length. It allows for object recycling, pre-allocation and stack allocations: static SizedObjectFactory BINOMIAL_FACTORY = new SizedObjectFactory { protected BinomialCoef create(int size) { return new BinomialCoef(size); } }; ... BinomialCoef bin = BINOMIAL_FACTORY.array(256);
