NoneAn abstract class, interface or naming convention which is used to state that the given object is used to write data to a file, stream, device or other destination
A Writer clause is often used as a part of a name of an object in object-oriented programming. Good examples are BufferedWriter from Java 6 or StreamWriter from C#.
Abstract writers are often defined as interfaces or abstract classes to provide means of making the process of writing separable from what is being written. In Java or.NET there are Writer implementations for files, network connections and, more general, streams.
