<PRE>
public <B>NodeComponent</B>()</PRE>
<DL>
<DD>Constructs a NodeComponent object with default parameters.
 The default values are as follows:
 <ul>
 duplicate on clone tree : false<br>

<PRE>
public void <B>setDuplicateOnCloneTree</B>(boolean&nbsp;duplicate)</PRE>
<DL>
<DD>Sets this node's duplicateOnCloneTree value.  The
 <i>duplicateOnCloneTree</i> value is used to determine if NodeComponent
 objects are to be duplicated or referenced during a
 <code>cloneTree</code> operation. A value of <code>true</code> means
  that this NodeComponent object should be duplicated, while a value
  of <code>false</code> indicates that this NodeComponent object's
  reference will be copied into the newly cloned object.  This value
  can be overriden via the <code>forceDuplicate</code> parameter of
  the <code>cloneTree</code> method.

<DL>
<DD>Returns this node's duplicateOnCloneTree value. The
 <i>duplicateOnCloneTree</i> value is used to determine if NodeComponent
 objects are to be duplicated or referenced during a
 <code>cloneTree</code> operation. A value of <code>true</code> means
  that this NodeComponent object should be duplicated, while a value
  of <code>false</code> indicates that this NodeComponent object's
  reference will be copied into the newly cloned object.  This value
  can be overriden via the <code>forceDuplicate</code> parameter of
  the <code>cloneTree</code> method.

<DL>
<DD>Used to create a new instance of a NodeComponent object.  This
 routine is called  by <code>cloneNode</code> to duplicate the 
 current node. <br>
 
 <code>cloneNodeComponent</code> should be overridden by any user
 subclassed <i>NodeComponent</i> objects. All subclasses must have their
 <code>cloneNodeComponent</code>
 method consist of the following lines:
 <P><blockquote><pre>
     public NodeComponent cloneNodeComponent(boolean forceDuplicate) {
         UserNodeComponent unc = new UserNodeComponent();
         unc.duplicateNodeComponent(this, forceDuplicate);
         return unc;
     }
