How can I access a variable defined inside a method by using reflection?
I have to create criteria in Hibernate. The database is attribute based.
Consider a movie. A movie can have many languages and many genres. e.g.
Movieid Property Value 1 Language Hindi 1 Language English 1 genre action 2 genre comedy
Let’s assume there are a thousand records of different movies. The user selects a set of genres(action) and languages(hindi, english) to filter the result. Now, I have to create criteria in this order : expression = (property= english and genre = action) or (property= hindi and genre = action)
For the implementation, I have to lookup into a local variable defined inside a for loop condition.
You can’t. If it’s defined in a method, is it a local variable defined in that scope only. Since the method had no state outside of its scope, you have nothing to access.
Accessing a class member (which, by definition, is a state) you can access via “regular” reflection.
