<div class="block">The <a href="../../../../../org/apache/commons/io/input/ObservableInputStream.html" title="class in org.apache.commons.io.input"><code>ObservableInputStream</code></a> allows, that an InputStream may be consumed
 by other receivers, apart from the thread, which is reading it.
 The other consumers are implemented as instances of <a href="../../../../../org/apache/commons/io/input/ObservableInputStream.Observer.html" title="class in org.apache.commons.io.input"><code>ObservableInputStream.Observer</code></a>. A
 typical application may be the generation of a <a href="http://docs.oracle.com/javase/7/docs/api/java/security/MessageDigest.html?is-external=true" title="class or interface in java.security"><code>MessageDigest</code></a> on the
 fly.
 <code>Note</code>: The <a href="../../../../../org/apache/commons/io/input/ObservableInputStream.html" title="class in org.apache.commons.io.input"><code>ObservableInputStream</code></a> is <em>not</em> thread safe,
 as instances of InputStream usually aren't.
 If you must access the stream from multiple threads, then synchronization, locking,
 or a similar means must be used.</div>
