## com.sun.jdi
Interface ClassLoaderReference

All Superinterfaces:
  Mirror, ObjectReference, Value

    public interface ClassLoaderReference

extends ObjectReference

A class loader object from the target VM. A ClassLoaderReference is an `ObjectReference` with additional access to classloader-specific information from the target VM. Instances ClassLoaderReference are obtained through calls to `ReferenceType.classLoader()`

Since:
  1.3
See Also:
  `ObjectReference`

Method Summary
`List<ReferenceType>` | `definedClasses()` Returns a list of all loaded classes that were defined by this class loader.
`List<ReferenceType>` | `visibleClasses()` Returns a list of all classes for which this class loader has been recorded as the initiating loader in the target VM.

Method Detail

### definedClasses

    List<ReferenceType> definedClasses()

  Returns a list of all loaded classes that were defined by this class loader. No ordering of this list guaranteed.

  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.

  Returns:
    a List of `ReferenceType` objects mirroring types loaded by this class loader. The list has length 0 if no types have been defined by this classloader.

### visibleClasses

    List<ReferenceType> visibleClasses()

  Returns a list of all classes for which this class loader has been recorded as the initiating loader in the target VM. The list contains ReferenceTypes defined directly by this loader (as returned by `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 revised 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.

  Returns:
    a List of `ReferenceType` objects mirroring classes initiated by this class loader. The list has length 0 if no classes are visible to this classloader.
