Hello IvyTeam,

Is there a way to get the list of parameters which are defined in the Signature of a process start element ? *I need this information before starting the process instance.

I checked the public API but such information is not available. So, I assume there is an Internal API that I can use ? Can you provide some code snipet?

Best Regards, Yordan

Yes there is indeed internal API to do this. The following example shows how to read process (IProcess) from a project and use the process model API to play with instances of RequestStart.

package com.axonivy.demo;

import java.util.List;
import java.util.Set;

import ch.ivyteam.ivy.environment.EnvironmentNotAvailableException;
import ch.ivyteam.ivy.environment.Ivy;
import ch.ivyteam.ivy.persistence.PersistencyException;
import ch.ivyteam.ivy.process.IProcess;
import ch.ivyteam.ivy.process.model.element.event.start.RequestStart;
import ch.ivyteam.ivy.resource.datamodel.ResourceDataModelException;

public class Startables {

    public static void logStarts() throws Exception
        Set<IProcess> allProcessInMyProject = Ivy.request().getProject().getProcesses(null);
        for(IProcess proc : allProcessInMyProject)
            List<RequestStart> starts = proc.getModel().search().type(RequestStart.class)
                .and(start -> start.isStartByHttpRequestAllowed())

    private static void log(RequestStart start)
        Ivy.log().info(start.getRequestPath().getLinkName()+" /signature="+start.getSignature().toSignatureString());

if you wan't all globally available process:

IProcessManager manager = DiCore.getGlobalInjector().getInstance(IProcessManager.class);
Set<IProcess> allProcessOnEngine = manager.getDataModels(null).getModels()
