<PRE>
public void <B>setOutputLocator</B>(<A HREF="../../javax/media/MediaLocator.html">MediaLocator</A>&nbsp;output)</PRE>
<DL>
<DD>Sets the output <code>MediaLocator</code> for this <CODE>DataSink</CODE>.
 This method should only be called once; an error is thrown if
 the locator has already been set.<DD><DL>

<A NAME="start()"><!-- --></A><H3>
start</H3>
<PRE>
public void <B>start</B>()
           throws java.io.IOException</PRE>
<DL>
<DD>Initiates data transfer. 
 You must call <CODE>open</CODE> before calling the <CODE>start</CODE> method.<DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Throws:</B><DD>java.io.IOException - If there are IO problems with the source

          throws java.io.IOException,
                 java.lang.SecurityException</PRE>
<DL>
<DD>Opens a connection to the destination described by
 the output <CODE>MediaLocator</CODE>. This method 
 establishes a channel between this <CODE>DataSink</CODE> and its destination.<DD><DL>
</DL>
</DD>
<DD><DL>
<DT><B>Throws:</B><DD>java.io.IOException - If there are IO problems
 when <CODE>open</CODE> is called.<DD>java.lang.SecurityException - If there are any security

<A NAME="close()"><!-- --></A><H3>
close</H3>
<PRE>
public void <B>close</B>()</PRE>
<DL>
<DD>Closes the connection to the destination described by the 
 output <CODE>MediaLocator</CODE>.
 This method frees the resources used to maintain a
 connection to the destination.
 If no resources are in use, <CODE>close</CODE> is ignored.
 If <CODE>stop</CODE> hasn't already been called,
 calling <CODE>close</CODE> stops the data transfer.
 A <CODE>DataSink</CODE> can no longer be used once it has been closed.<DD><DL>
