Objects that implement this interface can serve as a source of characters and can transfer one or more at a time to a java.nio.CharBuffer. Readable was added in Java 5.0 as a simple unifying API for java.nio.CharBuffer and character input stream subclasses of java.io.Reader. The java.util.Scanner class can parse input from any Readable object. See also Appendable.

public interface Readable {
// Public Instance Methods
