Method Detail

bufferedCopy

public static void bufferedCopy(InputStream input,
                                OutputStream output)
                         throws IOException
Deprecated. Buffering streams is actively harmful! See the class description as to why. Use copy(InputStream, OutputStream) instead.

Copy bytes from an InputStream to an OutputStream, with buffering. This is equivalent to passing a BufferedInputStream and BufferedOutputStream to copy(InputStream, OutputStream), and flushing the output stream afterwards. The streams are not closed after the copy.

Parameters:
input - DOCUMENT ME!
output - DOCUMENT ME!
Throws:
IOException - DOCUMENT ME!

contentEquals

public static boolean contentEquals(InputStream input1,
                                    InputStream input2)
                             throws IOException
Compare the contents of two Streams to determine if they are equal or not.

Parameters:
input1 - the first stream
input2 - the second stream
Returns:
true if the content of the streams are equal or they both don't exist, false otherwise
Throws:
IOException - DOCUMENT ME!
