An activation identifier (an instance of the class <code>ActivationID</code>) contains several pieces of information needed for activating an object: <ul> <li> a remote reference to the object's activator, and <li> a unique identifier for the object. </ul> <p> An activation id for an object can be obtained by registering an object with the activation system. Registration is accomplished in a few ways: <ul> <li>via the <code>Activatable.register</code> method <li>via the first <code>Activatable</code> constructor (that takes three arguments and both registers and exports the object, and <li>via the first <code>Activatable.exportObject</code> method that takes the activation descriptor, object and port as arguments; this method both registers and exports the object. </ul><P><DL><DT><B>Since: </B><DD>1.2</DD><DT><B>See Also: </B><DD><A HREF="../../../java/rmi/activation/Activatable.html"><CODE>Activatable</CODE></A>, <A HREF="../../../serialized-form.html#java.rmi.activation.ActivationID">Serialized Form</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="../../../java/rmi/activation/ActivationID.html#ActivationID(java.rmi.activation.Activator)">ActivationID</A></B>(<A HREF="../../../java/rmi/activation/Activator.html">Activator</A> activator)</CODE><BR> The constructor for <code>ActivationID</code> takes a single argument, activator, that specifies a remote reference to the activator responsible for activating the object associated with this identifier.</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> <A HREF="../../../java/rmi/Remote.html">Remote</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/activation/ActivationID.html#activate(boolean)">activate</A></B>(boolean force)</CODE><BR> Activate the object for this id.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/activation/ActivationID.html#equals(java.lang.Object)">equals</A></B>(<A HREF="../../../java/lang/Object.html">Object</A> obj)</CODE><BR> Compares two activation ids for content equality.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/activation/ActivationID.html#hashCode()">hashCode</A></B>()</CODE><BR> Returns a hashcode for the activation id.</TD></TR></TABLE>⌨️ 快捷键说明
