Hello all,
I've been spinning my wheels over this all day. I have 2 things I'm trying
to accomplish:
1- Wire up Hivemind to get singleton and inject it into my page.
2- If necessary, since I can not serialize my providers, data squeeze the
singleton.
Essentially, I call a synchronized current() method on a provider (with a
private constructor), which returns the singleton. My provider implements a
factory interface used to build the object returned.
This is where I'm at...please see if you can help!
hivemodule.xml
<service-point id="report" interface="com.myApp.ReportFactory"/>
<implementation service-id="reportMap">
<invoke-factory model="singleton">
<construct class="com.myApp.ReportProvider"
initialize-method="current"/>
</invoke-factory>
</implementation>
MyPage.page
<inject object="service:myReportingApp.reportMap" property="provider"/>
MyPage.java
public abstract AdminReportMapFactory getProvider();
ReportProvider .java
public class ReportProvider implements ReportFactory {
private static ReportProvider current = null;
private ReportProvider() {
// default constructor - needs to be private to enforce singleton
nature
super();
}
/**
* Get the singleton instance
* @return ReportProvider
*/
public static synchronized ReportProvider current() {
if (current == null) {
current = new ReportProvider();
}
return current;
}
public List lookup(String name, String reportID) {
return getFactory().lookupReportID(name, reportID);
}
private ReportFactory getFactory() {
return ReportFactoryImpl.getInstance();
}
