Class ReadWrapper

java.lang.Object
  com.calitha.io.ReadWrapper

public class ReadWrapper
extends Object

A ReadWrapper object is used to use read and write methods on an input stream and random access file without having to know which of those you you are currently dealing with.

The existence of the class is caused by the fact that an input stream and random access file do not have a common interface that define these methods.
