Hello, I’m starting with Flowable and doing some tests I used a script task to set instance variables with the execution.setVariable (x, y) method. My question is how can I know that other methods are in “execution” and what are their uses. I can not find this information in the documentation.  
Example

> execution.setVariable(“personInstanceVar”, person );

Thank you very much

Marcelo

The execution object is a java object that implements (amongst other, but most importantly) the following intefaces:

- [http://www.flowable.org/docs/javadocs/org/flowable/engine/runtime/Execution.html](http://www.flowable.org/docs/javadocs/org/flowable/engine/runtime/Execution.html)
- [http://www.flowable.org/docs/javadocs/org/flowable/engine/delegate/VariableScope.html](http://www.flowable.org/docs/javadocs/org/flowable/engine/delegate/VariableScope.html)

All methods in those interfaces are applicable to the execution object in a scrip.

the links have been update i suppose. could you please provide new ones? also, how is this “execution” object instance is available directly? is there also “runtimeService” available if i wanna use inside a groovy script task?
