Class UserFilesGenerator

java.lang.Object

EDU.purdue.jtb.generate.UserFilesGenerator

public class UserFilesGenerator
extends Object

Class UserFilesGenerator contains methods to generate: CODEJAVA

• the (grammar) user nodes classes (genUserXxx, using UserClassInfo),
• the hook interface and empty class files (genXxxEnterExitHook).

Class maintains a state, and is not supposed to be run in parallel threads (on the same grammar); however it internally uses different threads (streams) to generate the different user classes in parallel.
