<A NAME="reclaim(javax.swing.text.AttributeSet)"><!-- --></A><H3>
reclaim</H3>
<PRE>
public void <B>reclaim</B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A>&nbsp;a)</PRE>
<DL>
<DD>Returns a set no longer needed by the MutableAttributeSet implmentation.
 This is useful for operation under 1.1 where there are no weak 
 references.  This would typically be called by the finalize method
 of the MutableAttributeSet implementation.
 <p>
 This method is thread safe, although most Swing methods
 are not. Please see 
 <A HREF="http://java.sun.com/products/jfc/swingdoc-archive/threads.html">Threads

<DL>
<DD>Create a large set of attributes that should trade off
 space for time.  This set will not be shared.  This is
 a hook for subclasses that want to alter the behavior
 of the larger attribute storage format (which is 
 SimpleAttributeSet by default).   This can be reimplemented

 attribute conversion.<DD><DL>

<DL>
<DD>Writes a set of attributes to the given object stream
 for the purpose of serialization.  This will take
 special care to deal with static attribute keys that
 have been registered wit the 
 <code>registerStaticAttributeKey</code> method.
 Any attribute key not regsitered as a static key
 will be serialized directly.  All values are expected
 to be serializable.<DD><DL>

<DL>
<DD>Reads a set of attributes from the given object input
 stream that have been previously written out with
 <code>writeAttributeSet</code>.  This will try to restore
 keys that were static objects to the static objects in
 the current virtual machine considering only those keys
 that have been registered with the 
 <code>registerStaticAttributeKey</code> method.
 The attributes retrieved from the stream will be placed
 into the given mutable set.<DD><DL>

registerStaticAttributeKey</H3>
<PRE>
public static void <B>registerStaticAttributeKey</B>(<A HREF="../../../java/lang/Object.html">Object</A>&nbsp;key)</PRE>
<DL>
<DD>Registers an object as a static object that is being
 used as a key in attribute sets.  This allows the key
 to be treated specially for serialization.
 <p>
 For operation under a 1.1 virtual machine, this
 uses the value returned by <code>toString</code>
 concatenated to the classname.  The value returned
 by toString should not have the class reference
 in it (ie it should be reimplemented from the 
 definition in Object) in order to be the same when
 recomputed later.<DD><DL>
