ArrayType - Type of the primitive array; e.g., double[].BaseType - Boxed type of the array element; e.g., Double.public abstract class AbstractPrimitiveArray<ArrayType,BaseType> extends AbstractList<BaseType> implements PrimitiveArray<ArrayType,BaseType>
This class makes it easy to implement extensible arrays backed by fixed-size primitive type arrays, re-allocating and copying data as needed. To avoid frequent re-allocation, by default, the fixed-size array will be expanded by 50% when running out of space.
