Returns a list of all loaded classes that were defined by this
class loader.

List<ReferenceType> definedClasses()
The returned list will include reference types loaded at least to the point of preparation and types (like array) for which preparation is not defined.
ReferenceType

loaded by this class loader. The list has length 0 if no types
have been defined by this classloader.List<ReferenceType> visibleClasses()
definedClasses()
) and any types for which
loading was delegated by this class loader to another class loader.
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.
See The Java™ Virtual Machine Specification, section 5.3 - Creation and Loading for more information on the initiating classloader.
Note that unlike definedClasses()
and 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 ClassNotPreparedException
.
Use ReferenceType.isPrepared()
to determine if
a reference type is prepared.
