See <tt>ObjectFactory</tt> for details. <p> A <tt>DirObjectFactory</tt> extends <tt>ObjectFactory</tt> by allowing an <tt>Attributes</tt> instance to be supplied to the <tt>getObjectInstance()</tt> method. <tt>DirObjectFactory</tt> implementations are intended to be used by <tt>DirContext</tt> service providers. The service provider, in addition reading an object from the directory, might already have attributes that are useful for the object factory to check to see whether the factory is supposed to process the object. For instance, an LDAP-style service provider might have read the "objectclass" of the object. A CORBA object factory might be interested only in LDAP entries with "objectclass=corbaObject". By using the attributes supplied by the LDAP service provider, the CORBA object factory can quickly eliminate objects that it need not worry about, and non-CORBA object factories can quickly eliminate CORBA-related LDAP entries.<P><DL><DT><B>Since: </B><DD>1.3</DD><DT><B>See Also: </B><DD><A HREF="../../../javax/naming/spi/NamingManager.html#getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable)"><CODE>NamingManager.getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable)</CODE></A>, <A HREF="../../../javax/naming/spi/DirectoryManager.html#getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable, javax.naming.directory.Attributes)"><CODE>DirectoryManager.getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable, javax.naming.directory.Attributes)</CODE></A>, <A HREF="../../../javax/naming/spi/ObjectFactory.html"><CODE>ObjectFactory</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="../../../java/lang/Object.html">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/naming/spi/DirObjectFactory.html#getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable, javax.naming.directory.Attributes)">getObjectInstance</A></B>(<A HREF="../../../java/lang/Object.html">Object</A> obj, <A HREF="../../../javax/naming/Name.html">Name</A> name, <A HREF="../../../javax/naming/Context.html">Context</A> nameCtx, <A HREF="../../../java/util/Hashtable.html">Hashtable</A> environment, <A HREF="../../../javax/naming/directory/Attributes.html">Attributes</A> attrs)</CODE><BR> Creates an object using the location or reference information, and attributes specified.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_javax.naming.spi.ObjectFactory"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface javax.naming.spi.<A HREF="../../../javax/naming/spi/ObjectFactory.html">ObjectFactory</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/naming/spi/ObjectFactory.html#getObjectInstance(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable)">getObjectInstance</A></CODE></TD>⌨️ 快捷键说明
