Class LinkedReaderAndWriter

java.lang.Object
  edu.rice.cs.plt.io.LinkedReaderAndWriter

public class LinkedReaderAndWriter
extends java.lang.Object

Coordinates reading and writing from the same source. Ensures that the given Writer will never write past the location of the Reader, potentially corrupting its contents. When the Writer needs to write more characters than have been read, a buffer is used to store the characters in between. In order to take advantage of these linking features, all interaction with the user-provided Reader and Writer must subsequently take place via the results of reader() and writer(), respectively.
