Java event handler example

Like the JavaScript event handler in the previous section, the Java code example in Listing 24-2 uses the getUserRoles( ) method to retrieve the user’s roles and displays the contents of a table if the user role is Manager. The TableEH class extends the TableEventAdapter class and implements the event-handler script in the onPrepare event method.

Listing 24-2

Java event handler class

package server.api.eh;

 

import java.util.List;

 

import org.eclipse.birt.report.engine.api.script.IReportContext;

import org.eclipse.birt.report.engine.api.script.element.ITable;

import org.eclipse.birt.report.engine.api.script.eventadapter.TableEventAdapter;

 

import com.actuate.reportapi.engine.IServerContext;

 

public class TableEH extends TableEventAdapter {

  

  public void onPrepare(ITable tbl, IReportContext reportContext)

  {

 

    IServerContext scontext;

    scontext = (IServerContext)reportContext.getAppContext().get("ServerContext");

    List<String> userRoles = scontext.getUserRoles();

    scontext.appendToJobStatus("The user roles are:" + userRoles+"\n");

    for (int i = 0; i < userRoles.size(); i++)

    {

      if ( userRoles.get(i).contentEquals("Manager"))

      {

        reportContext.setGlobalVariable("HideDetails", "false");

        scontext.appendToJobStatus("The user has a Manager role\n");  

        break;

      }

    }

  }

}
