As internal representation, it is not exposed to the user. <P>RelationSupport class conforms to the design patterns of standard MBean. So the user can decide to instantiate a RelationSupport object himself as a MBean (as it follows the MBean design patterns), to register it in the MBean Server, and then to add it in the Relation Service. <P>The user can also, when creating his own MBean relation class, have it extending RelationSupport, to retrieve the implementations of required interfaces (see below). <P>It is also possible to have in a user relation MBean class a member being a RelationSupport object, and to implement the required interfaces by delegating all to this member. <P> RelationSupport implements the Relation interface (to be handled by the Relation Service). <P>It implements also the MBeanRegistration interface to be able to retrieve the MBean Server where it is registered (if registered as a MBean) to access to its Relation Service.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><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="../../../javax/management/relation/RelationSupport.html#RelationSupport(java.lang.String, javax.management.ObjectName, javax.management.MBeanServer, java.lang.String, javax.management.relation.RoleList)">RelationSupport</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> theRelId, <A HREF="../../../javax/management/ObjectName.html" title="class in javax.management">ObjectName</A> theRelServiceName, <A HREF="../../../javax/management/MBeanServer.html" title="interface in javax.management">MBeanServer</A> theRelServiceMBeanServer, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> theRelTypeName, <A HREF="../../../javax/management/relation/RoleList.html" title="class in javax.management.relation">RoleList</A> theRoleList)</CODE><BR> Creates object. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/management/relation/RelationSupport.html#RelationSupport(java.lang.String, javax.management.ObjectName, java.lang.String, javax.management.relation.RoleList)">RelationSupport</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> theRelId, <A HREF="../../../javax/management/ObjectName.html" title="class in javax.management">ObjectName</A> theRelServiceName, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> theRelTypeName, <A HREF="../../../javax/management/relation/RoleList.html" title="class in javax.management.relation">RoleList</A> theRoleList)</CODE><BR> Creates object. </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><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="../../../javax/management/relation/RoleResult.html" title="class in javax.management.relation">RoleResult</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/management/relation/RelationSupport.html#getAllRoles()">getAllRoles</A></B>()</CODE><BR> Returns all roles present in the relation.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Map.html" title="class or interface in java.util">Map</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/management/relation/RelationSupport.html#getReferencedMBeans()">getReferencedMBeans</A></B>()</CODE><BR> Retrieves MBeans referenced in the various roles of the relation.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/management/relation/RelationSupport.html#getRelationId()">getRelationId</A></B>()</CODE><BR> Returns relation identifier (used to uniquely identify the relation inside the Relation Service).</TD></TR>⌨️ 快捷键说明
