cvs commit: jakarta-commons-sandbox/io/src/java/org/apache/commons/io CountingOutputStream.java TeeOutputStream.java

bayard      02/02/22 20:29:53

  Added:       io/src/java/org/apache/commons/io CountingOutputStream.java
                        TeeOutputStream.java
  Log:
  Pretty standard classes. A stream to count the number of bytes that
  go by it (logging) and a stream for branching into two streams.
