here are three questions about java scripting api, please help.
(1) How can I get all the variables created inside my engine?
There are two kinds of variables: first kind is Java objects that I have put inside the engine, and second kind is the variables created inside my script, such as 'var a = 4;'. How can I list all the variables of that two kinds, or at least the second kind?
(2) Is there is a way to make 'import static' to the engine? I dont want to write MyClass.MyEnum.MyEnumItem inside my script every time. Also, I cannot put the whole enum into the engine with engine.put("MyEnum", MyEnum); I can put only enum items separately: engine.put("MyEnum", MyEnum.EnumItemA);. Thats why I ask about static import.
(3) How can I cast engine variables back to java variables inside my java code?
Here is my example:
