def enclosingMethodAttribute(classSym: Symbol, classDesc: Symbol => String, methodDesc: Symbol => String): Option[EnclosingMethodEntry]

Data for emitting an EnclosingMethod attribute. None if classSym is a member class (not an anonymous or local class). See doc in BTypes.

Data for emitting an EnclosingMethod attribute. None if classSym is a member class (not an anonymous or local class). See doc in BTypes.

The class is parametrized by two functions to obtain a bytecode class descriptor for a class symbol, and to obtain a method signature descriptor fro a method symbol. These function depend on the implementation of GenASM / GenBCode, so they need to be passed in.

def isAnonymousOrLocalClass(classSym: Symbol): Boolean

True if classSym is an anonymous class or a local class. I.e., false if classSym is a member class. This method is used to decide if we should emit an EnclosingMethod attribute. It is also used to decide whether the "owner" field in the InnerClass attribute should be null.
