Hi,
I am trying to embbed Groovy in Java app.
I know that through Binding object I can bind variables from Java app to Groovy script and use it in script. In my app I am trying to change value of Java variable with Groovy script and it works well:

My question is: is there some way to make java variables updates immediately after shell.evaluate() method calling? For example, if I would have 1000 variables i don't want call for every variable

because of one variable change in script code. Is it possible to ommit this step and update java variables with new value automatically?
 
Don't get me started about those stupid light bulbs.
