<PRE>
public <A HREF="../../../javax/sound/sampled/Line.Info.html">Line.Info</A> <B>getLineInfo</B>()</PRE>

 line.<DD><DL>

<A NAME="open()"><!-- --></A><H3>
open</H3>
<PRE>
public void <B>open</B>()
          throws <A HREF="../../../javax/sound/sampled/LineUnavailableException.html">LineUnavailableException</A></PRE>
<DL>
<DD>Opens the line, indicating that it should acquire any required
 system resources and become operational.  
 If this operation 
 succeeds, the line is marked as open, and an <code>OPEN</code> event is dispatched
 to the line's listeners.
 <p>
 Note that some lines, once closed, cannot be reopened.  Attempts
 to reopen such a line will always result in an <code>LineUnavailableException</code>.
 <p>
 Some types of lines have configurable properties that may affect 
 resource allocation.   For example, a <code>DataLine</code> must
 be opened with a particular format and buffer size.  Such lines 
 should provide a mechanism for configuring these properties, such
 as an additional <code>open</code> method or methods which allow
 an application to specify the desired settings.  
 <p>
 This method takes no arguments, and opens the line with the current 
 settings.  For <code><A HREF="../../../javax/sound/sampled/SourceDataLine.html"><CODE>SourceDataLine</CODE></A></code> and 
 <code><A HREF="../../../javax/sound/sampled/TargetDataLine.html"><CODE>TargetDataLine</CODE></A></code> objects, this means that the line is
 opened with default settings.  For a <code><A HREF="../../../javax/sound/sampled/Clip.html"><CODE>Clip</CODE></A></code>, however, 
 the buffer size is determined when data is loaded.  Since this method does not
 allow the application to specify any data to load, it allocates 
 resources for a clip with zero frames of data, and there is no
 means for subsequently loading data into that clip.  Therefore, 
 you should instead use one of the <code>open</code> methods provided in 
 the <code>Clip</code> interface to load data into the <code>Clip</code>.<DD><DL>
<DT><B>Throws:</B><DD><CODE><A HREF="../../../javax/sound/sampled/LineUnavailableException.html">LineUnavailableException</A></CODE> - if the line cannot be
