PolicyManager returns objects typed as Policy Value Sets, which arederivatives of simple Maps. A Policy Value Set (PVS) is a set ofapplication specific attributes that create points of variability insome apsect of the calling application. The goal of the Policy ManagerAPI is to provide the same API to policy consumers, or applications ,independant of the platforms they are calling from. For example, thesame policy code could be made from a server side portlet running withinWebsphere Portal, as well as from an application on the rich client. <BR><BR>Targets are rules engine objects to assist policy in navigating the treeof subpolicies. Execution of a Target results in a list of profiles,that provide the next possible step down the policy subtree. Targets'uses are limited to the server side consumers of policy. Alternative toTargets, if policy consumers know the policy tree topology, they canform their own <I>policy path</I> in the form of a String. <BR><BR>Use the WebSphere Portal JNDI portlet service lookup mechanism to locatethe PolicyManager implementation.</P><p>Usage examples:<ul> <li>Code with a known policy path:<pre><code> import com.ibm.policy.manager.*; import javax.naming.InitialContext; import javax.naming.Context; import javax.naming.NamingException; ... PolicyManagerService pms; javax.naming.Context ctx = new javax.naming.InitialContext(); try { pms = (PolicyManagerService)ctx.lookup("portal:service/policy/PolicyManager"); } catch(javax.naming.NameNotFoundException ex) { ... error handling ... } ... // request the service via the home interface PolicyManager pManager = pms.getPolicyManager(); String knownPolicyPath="Taxes/UnitedStates/NorthCarolina"; PolicyValueSet set=pManager.getPVSByPath(knownPolicyPath); int taxRate=set.get("rate");</CODE></PRE></li> <li>Code requesting evaluation of the current request to determine applicable policy.<PRE><CODE> import com.ibm.policy.manager.*; import com.ibm.policy.manager.portal.*; import javax.naming.InitialContext; import javax.naming.Context; import javax.naming.NamingException; ... PolicyManager pManager=null; PolicyManagerService pms; Context ctx = new InitialContext(); try { pms = (PolicyManagerService)ctx.lookup("portal:service/policy/PolicyManager"); } catch(javax.naming.NameNotFoundException ex) { ... error handling ... } ... // request the service via the home interface PolicyManager pManager = pms.getPolicyManager(); String knownPolicyType="Taxes"; RuleContext ruleCtx=new PortletRequestRuleContext(portletRequest); Target tar=pManager.createTarget(ruleCtx); PolicyValueSet set=pManager.getPVSByTarget(tar, knownPolicyType); Integer taxRate=set.get("rate");</CODE></PRE></li></ul><p>Please note that as a general rule, all of the interfaces of this APImust not be implemented. Your code may only implement an interface ifthe according interface description explicitely states that this isallowed. <br><P><P><HR><!-- ======= START OF BOTTOM NAVBAR ====== --><A NAME="navbar_bottom"><!-- --></A><A HREF="#skip-navbar_bottom" title="Skip navigation links"></A><TABLE BORDER="0" WIDTH="100%" CELLPADDING="1" CELLSPACING="0" SUMMARY=""><TR><TD COLSPAN=3 BGCOLOR="#EEEEFF" CLASS="NavBarCell1"><A NAME="navbar_bottom_firstrow"><!-- --></A><TABLE BORDER="0" CELLPADDING="0" CELLSPACING="3" SUMMARY=""> <TR ALIGN="center" VALIGN="top"> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../overview-summary.html"><FONT CLASS="NavBarFont1"><B>Overview</B></FONT></A> </TD> <TD BGCOLOR="#FFFFFF" CLASS="NavBarCell1Rev"> <A HREF="#main"><FONT CLASS="NavBarFont1Rev"><B>Package</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <FONT CLASS="NavBarFont1">Class</FONT> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-tree.html"><FONT CLASS="NavBarFont1"><B>Tree</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../serialized-form.html"><FONT CLASS="NavBarFont1"><B>Serialized</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../deprecated-list.html"><FONT CLASS="NavBarFont1"><B>Deprecated</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../index-all.html"><FONT CLASS="NavBarFont1"><B>Index</B></FONT></A> </TD> <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../help-doc.html"><FONT CLASS="NavBarFont1"><B>Help</B></FONT></A> </TD> </TR></TABLE></TD><TD ALIGN="right" VALIGN="top" ROWSPAN=3><EM></EM></TD></TR><TR><TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> <A HREF="../../../../com/ibm/content/binder/service/package-summary.html"><B>PREV PACKAGE</B></A> <A HREF="../../../../com/ibm/portal/package-summary.html"><B>NEXT PACKAGE</B></A></FONT></TD><TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> <A HREF="../../../../index.html" target="_top"><B>FRAMES</B></A> <A HREF="package-summary.html" target="_top"><B>NO FRAMES</B></A> <SCRIPT type="text/javascript"> <!-- if(window==top) { document.writeln('<A HREF="../../../../allclasses-noframe.html"><B>All Classes</B></A>'); } //--></SCRIPT><NOSCRIPT> <A HREF="../../../../allclasses-noframe.html"><B>All Classes</B></A></NOSCRIPT></FONT></TD></TR></TABLE><A NAME="skip-navbar_bottom"></A><!-- ======== END OF BOTTOM NAVBAR ======= --><HR></BODY></HTML>?? 快捷鍵說明
