This class is used in <code>Request</code> operations to describe the contexts that need to be resolved and sent with the invocation. (A context is resolved by giving a property name and getting back the value associated with it.) This is done by calling the <code>Context</code> method <code>get_values</code> and supplying a string from a <code>ContextList</code> object as the third parameter. The method <code>get_values</code> returns an <code>NVList</code> object containing the <code>NamedValue</code> objects that hold the value(s) identified by the given string. <P> A <code>ContextList</code> object is created by the ORB, as illustrated here: <PRE> ORB orb = ORB.init(args, null); org.omg.CORBA.ContextList ctxList = orb.create_context_list(); </PRE> The variable <code>ctxList</code> represents an empty <code>ContextList</code> object. Strings are added to the list with the method <code>add</code>, accessed with the method <code>item</code>, and removed with the method <code>remove</code>.<P><DL><DT><B>Since: </B><DD>JDK1.2</DD><DT><B>See Also: </B><DD><A HREF="../../../org/omg/CORBA/Context.html"><CODE>Context</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/omg/CORBA/ContextList.html#ContextList()">ContextList</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== 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>abstract void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ContextList.html#add(java.lang.String)">add</A></B>(<A HREF="../../../java/lang/String.html">String</A> ctx)</CODE><BR> Adds a <code>String</code> object to this <code>ContextList</code> object.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ContextList.html#count()">count</A></B>()</CODE><BR> Returns the number of <code>String</code> objects in this <code>ContextList</code> object.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract <A HREF="../../../java/lang/String.html">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ContextList.html#item(int)">item</A></B>(int index)</CODE><BR> Returns the <code>String</code> object at the given index.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ContextList.html#remove(int)">remove</A></B>(int index)</CODE><BR> Removes the <code>String</code> object at the given index.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.lang.<A HREF="../../../java/lang/Object.html">Object</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../java/lang/Object.html#clone()">clone</A>, <A HREF="../../../java/lang/Object.html#equals(java.lang.Object)">equals</A>, <A HREF="../../../java/lang/Object.html#finalize()">finalize</A>, <A HREF="../../../java/lang/Object.html#getClass()">getClass</A>, <A HREF="../../../java/lang/Object.html#hashCode()">hashCode</A>, <A HREF="../../../java/lang/Object.html#notify()">notify</A>, <A HREF="../../../java/lang/Object.html#notifyAll()">notifyAll</A>, <A HREF="../../../java/lang/Object.html#toString()">toString</A>, <A HREF="../../../java/lang/Object.html#wait()">wait</A>, <A HREF="../../../java/lang/Object.html#wait(long)">wait</A>, <A HREF="../../../java/lang/Object.html#wait(long, int)">wait</A></CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><A NAME="constructor_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Constructor Detail</B></FONT></TD></TR></TABLE><A NAME="ContextList()"><!-- --></A><H3>ContextList</H3><PRE>public <B>ContextList</B>()</PRE><DL></DL><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="count()"><!-- --></A><H3>count</H3><PRE>public abstract int <B>count</B>()</PRE><DL><DD>Returns the number of <code>String</code> objects in this <code>ContextList</code> object.<DD><DL><DT><B>Returns:</B><DD>an <code>int</code> representing the number of <code>String</code>s in this <code>ContextList</code> object</DL></DD></DL><HR><A NAME="add(java.lang.String)"><!-- --></A><H3>add</H3><PRE>public abstract void <B>add</B>(<A HREF="../../../java/lang/String.html">String</A> ctx)</PRE><DL><DD>Adds a <code>String</code> object to this <code>ContextList</code> object.<DD><DL><DT><B>Parameters:</B><DD><CODE>ctx</CODE> -
