Class LinkedInputAndOutputStream

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

public class LinkedInputAndOutputStream
extends java.lang.Object

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