Clarification about DelegateExecution and Execution

[gokceng1]

Hi,
The classes I've mentioned are:

org.activiti.engine.runtime.Execution
org.activiti.engine.delegate.DelegateExecution

The latter is used in JavaDelegate and ExecutionListeners. The former is the result of some RuntimeService API methods. Is there a relation between them? Is casting one to another is safe or may I use one of them's id to get/query another?

Afaik, DelegateExecution or ExecutionEntity is a small representation of an Execution at some activity. At each step Activiti can supply DelegateExecution or ExecutionEntity via ExecutionListener or JavaDelegate methods. I can get the main/broader view of the related execution using runtimeService.createExecutionQuery() method.

If there are some other relations or explanations over those classes could you please explain?

Thanks.

You can discard ExecutionEntity totally. I've noticed it's implementation of those two other interfaces.

Any idea?

DelegateExecution hides a bit of the complexity so people can't burn their fingers when using it in a JavaDelegate.
