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<BinomialCoef> BINOMIAL_FACTORY = new SizedObjectFactory<BinomialCoef> {
         protected BinomialCoef create(int size) {
             return new BinomialCoef(size);
         }
     };
     ...
     BinomialCoef bin = BINOMIAL_FACTORY.array(256);
