Introduction

In this page you can find the example usage for org.apache.commons.net.io Util copyStream.

Prototype

public static final long copyStream(InputStream source, OutputStream dest, int bufferSize, long streamSize,
        CopyStreamListener listener) throws CopyStreamException 

Source Link

Document

Copies the contents of an InputStream to an OutputStream using a copy buffer of a given size and notifies the provided CopyStreamListener of the progress of the copy operation by calling its bytesTransferred(long, int) method after each write to the destination.
