Each mutation of the attribute set can be used to exchange a previous AttributeSet instance with another, preserving the possibility of the AttributeSet remaining immutable. An implementation is provided by the StyleContext class. The Element implementations provided by this class use this interface to provide their MutableAttributeSet implementations, so that different AttributeSet compression techniques can be employed. The method <code>getAttributeContext</code> should be implemented to return the object responsible for implementing the desired compression technique.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../javax/swing/text/StyleContext.html"><CODE>StyleContext</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#addAttribute(javax.swing.text.AttributeSet, java.lang.Object, java.lang.Object)">addAttribute</A></B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> old, <A HREF="../../../java/lang/Object.html">Object</A> name, <A HREF="../../../java/lang/Object.html">Object</A> value)</CODE><BR> Adds an attribute to the given set, and returns the new representative set.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#addAttributes(javax.swing.text.AttributeSet, javax.swing.text.AttributeSet)">addAttributes</A></B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> old, <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> attr)</CODE><BR> Adds a set of attributes to the element.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#getEmptySet()">getEmptySet</A></B>()</CODE><BR> Fetches an empty AttributeSet.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#reclaim(javax.swing.text.AttributeSet)">reclaim</A></B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> a)</CODE><BR> Reclaims an attribute set.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#removeAttribute(javax.swing.text.AttributeSet, java.lang.Object)">removeAttribute</A></B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> old, <A HREF="../../../java/lang/Object.html">Object</A> name)</CODE><BR> Removes an attribute from the set.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/swing/text/AbstractDocument.AttributeContext.html#removeAttributes(javax.swing.text.AttributeSet, javax.swing.text.AttributeSet)">removeAttributes</A></B>(<A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> old, <A HREF="../../../javax/swing/text/AttributeSet.html">AttributeSet</A> attrs)</CODE><BR> Removes a set of attributes for the element.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor">⌨️ 快捷键说明
