It is usually used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has a CORBA Object reference as an "out" or "inout" parameter, the programmer must pass an instance of <code>ObjectHolder</code> as the corresponding parameter in the method invocation; for "inout" parameters, the programmer must also fill the "in" value to be sent to the server. Before the method invocation returns, the ORB will fill in the value corresponding to the "out" value returned from the server. <P> If <code>myObjectHolder</code> is an instance of <code>ObjectHolder</code>, the value stored in its <code>value</code> field can be accessed with <code>myObjectHolder.value</code>.<P><DL><DT><B>Since: </B><DD>JDK1.2</DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/omg/CORBA/Object.html">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ObjectHolder.html#value">value</A></B></CODE><BR> The <code>Object</code> value held by this <code>ObjectHolder</code> object.</TD></TR></TABLE> <!-- ======== 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/ObjectHolder.html#ObjectHolder()">ObjectHolder</A></B>()</CODE><BR> Constructs a new <code>ObjectHolder</code> object with its <code>value</code> field initialized to <code>null</code>.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/omg/CORBA/ObjectHolder.html#ObjectHolder(org.omg.CORBA.Object)">ObjectHolder</A></B>(<A HREF="../../../org/omg/CORBA/Object.html">Object</A> initial)</CODE><BR> Constructs a new <code>ObjectHolder</code> object with its <code>value</code> field initialized to the given <code>Object</code>.</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> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ObjectHolder.html#_read(org.omg.CORBA.portable.InputStream)">_read</A></B>(<A HREF="../../../org/omg/CORBA/portable/InputStream.html">InputStream</A> input)</CODE><BR> Reads from <code>input</code> and initalizes the value in this <code>ObjectHolder</code> object with the unmarshalled data.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/omg/CORBA/TypeCode.html">TypeCode</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/omg/CORBA/ObjectHolder.html#_type()">_type</A></B>()</CODE><BR> Returns the TypeCode corresponding to the value held in this <code>ObjectHolder</code> object</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="../../../org/omg/CORBA/ObjectHolder.html#_write(org.omg.CORBA.portable.OutputStream)">_write</A></B>(<A HREF="../../../org/omg/CORBA/portable/OutputStream.html">OutputStream</A> output)</CODE>⌨️ 快捷键说明
