definedClassesReturns a list of all classes defined by this class loader. No ordering of this list guaranteed. The returned list will include all reference types, including hidden classes or interfaces, loaded at least to the point of preparation, and types (like array) for which preparation is not defined.
ReferenceTypeobjects mirroring types defined by this class loader. The list has length 0 if no types have been defined by this classloader.
visibleClassesReturns a list of all classes which this class loader can find by name via
Class::forNameand bytecode linkage in the target VM. That is, all classes for which this class loader has been recorded as an initiating loader.
Each class in the returned list was created by this class loader either by defining it directly or by delegation to another class loader (see JVMS 5.3).
The visible class list has useful properties with respect to the type namespace. A particular type name will occur at most once in the list. Each field or variable declared with that type name in a class defined by this class loader must be resolved to that single type.
No ordering of the returned list is guaranteed.
Note that unlike
VirtualMachine.allClasses(), some of the returned reference types may not be prepared. Attempts to perform some operations on unprepared reference types (e.g.
fields()) will throw a
ReferenceType.isPrepared()to determine if a reference type is prepared.
