getFormats</H3>
<PRE>
public <A HREF="../../../javax/sound/sampled/AudioFormat.html">AudioFormat</A>[] <B>getFormats</B>()</PRE>
<DL>
<DD>Obtains a set of audio formats supported by the data line.
 Note that <code>isFormatSupported(AudioFormat)</code> might return
 <code>true</code> for certain additional formats that are missing from 
 the set returned by <code>getFormats()</code>.  The reverse is not
 the case: <code>isFormatSupported(AudioFormat)</code> is guaranteed to return
 <code>true</code> for all formats returned by <code>getFormats()</code>.<DD><DL>

 The default implementation of this method simply returns <code>true</code> if
 the specified format matches any of the supported formats.<DD><DL>

 addition, this object's minimum buffer size must be at least as
 large as that of the object specified, its maximum buffer size must
 be at most as large as that of the object specified, and all of its
 formats must match formats supported by the object specified.<DD><DL>
