public abstract class AbstractByteBigList extends AbstractByteCollection implements ByteBigList, ByteStack
An abstract class providing basic methods for big lists implementing a type-specific big list interface.

Most of the methods in this class are optimized with the assumption that the List will have have constant-time random access. If this is not the case, you should probably at least override listIterator(long) and the xAll() methods (such as addAll(long, java.util.Collection<? extends java.lang.Byte>)) with a more appropriate iteration scheme. Note the subList(long, long) method is cognizant of random-access or not, so that need not be reimplemented.
