When a caller binds an object using <tt>DirContext.bind()</tt>, he might also specify a set of attributes to be bound with the object. The object and attributes to be bound are passed to the <tt>getStateToBind()</tt> method of a factory. If the factory processes the object and attributes, it returns a corresponding pair of object and attributes to be bound. If the factory does not process the object, it must return null.<p> For example, a caller might bind a printer object with some printer-related attributes.<blockquote><pre> ctx.rebind("inky", printer, printerAttrs);</pre></blockquote> An LDAP service provider for <tt>ctx</tt> uses a <tt>DirStateFactory</tt> (indirectly via <tt>DirectoryManager.getStateToBind()</tt>) and gives it <tt>printer</tt> and <tt>printerAttrs</tt>. A factory for an LDAP directory might turn <tt>printer</tt> into a set of attributes and merge that with <tt>printerAttrs</tt>. The service provider then uses the resulting attributes to create an LDAP entry and updates the directory. <p> Since <tt>DirStateFactory</tt> extends <tt>StateFactory</tt>, it has two <tt>getStateToBind()</tt> methods, where one differs from the other by the attributes argument. <tt>DirectoryManager.getStateToBind()</tt> will only use the form that accepts the attributes argument, while <tt>NamingManager.getStateToBind()</tt> will only use the form that does not accept the attributes argument. <p> Either form of the <tt>getStateToBind()</tt> method of a DirStateFactory may be invoked multiple times, possibly using different parameters. The implementation is thread-safe.<P><DL><DT><B>Since: </B><DD>1.3</DD><DT><B>See Also: </B><DD><A HREF="../../../javax/naming/spi/DirectoryManager.html#getStateToBind(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable, javax.naming.directory.Attributes)"><CODE>DirectoryManager.getStateToBind(java.lang.Object, javax.naming.Name, javax.naming.Context, java.util.Hashtable, javax.naming.directory.Attributes)</CODE></A>, <A HREF="../../../javax/naming/spi/DirObjectFactory.html"><CODE>DirObjectFactory</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><A NAME="inner_class_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Inner Class Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static class</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/naming/spi/DirStateFactory.Result.html">DirStateFactory.Result</A></B></CODE><BR> An object/attributes pair for returning the result of DirStateFactory.getStateToBind().</TD></TR></TABLE> <!-- =========== 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">⌨️ 快捷键说明
