Persistence in Java Virtual Machine (vars etc)

[Charles Delfs]

Since I'm not a Java guru yet, here's a question,

 

Can and how do I keep variables and states etc. in my java (groovy) between FMP scripts etc.

 

Say I want to have an entire program running and that would communicate with FMP via script calls etc, how would I do that?

 

or ... its the environment totally destroyed at the end of the current script master call once control is passed back to FMP?

AFAIK the JVM is created on opening FMP with ScriptMAster installed and destroyed on exit

 

Any Groovy 'variables' you create during the script are available using SMGetVariable("var") until you run another function when they are destroyed - so you will need to set some FM variables for any kind of persistence.

BUT because the JVM is still alive you can put things into an Expando to store them (see posts from Todd Geist on his site on this)

Great, does anyone have a link to Todd's article, I see lots of references but not the blog itself.
