Enum Class MethodHandles.Lookup.ClassOption
- All Implemented Interfaces:
- Serializable,- Comparable<MethodHandles.Lookup.ClassOption>,- Constable
- Enclosing class:
- MethodHandles.Lookup
The set of class options that specify whether a hidden class created by
 
Lookup::defineHiddenClass method is dynamically added as a new member
 to the nest of a lookup class and/or whether a hidden class has
 a strong relationship with the class loader marked as its defining loader.- Since:

Enum Constant Details- 
NESTMATESpecifies that a hidden class be added to nest of a lookup class as a nestmate.A hidden nestmate class has access to the private members of all classes and interfaces in the same nest. - See Also:
 
- 
STRONGSpecifies that a hidden class has a strong relationship with the class loader marked as its defining loader, as a normal class or interface has with its own defining loader. This means that the hidden class may be unloaded if and only if its defining loader is not reachable and thus may be reclaimed by a garbage collector (JLS 12.7).By default, a hidden class or interface may be unloaded even if the class loader that is marked as its defining loader is reachable. - See Java Language Specification:
