## Interface InterfaceType

- All Superinterfaces:
    Accessible, Comparable<ReferenceType>, Mirror, ReferenceType, Type

      @Exported
      public interface InterfaceType
      extends ReferenceType

  A mirror of an interface in the target VM. An InterfaceType is a refinement of `ReferenceType` that applies to true interfaces in the JLS sense of the definition (not a class, not an array type). An interface type will never be returned by `ObjectReference.referenceType()`, but it may be in the list of implemented interfaces for a `ClassType` that is returned by that method.
  Since:
    1.3
  See Also:
    `ObjectReference`

- - ### Method Detail

    - #### superinterfaces

          List<InterfaceType> superinterfaces()

      Gets the interfaces directly extended by this interface. The returned list contains only those interfaces this interface has declared to be extended.
      Returns:
        a List of `InterfaceType` objects each mirroring an interface extended by this interface. If none exist, returns a zero length List.
      Throws:
        `ClassNotPreparedException` - if this class not yet been prepared.

    - #### subinterfaces

          List<InterfaceType> subinterfaces()

      Gets the currently prepared interfaces which directly extend this interface. The returned list contains only those interfaces that declared this interface in their "extends" clause.
      Returns:
        a List of `InterfaceType` objects each mirroring an interface extending this interface. If none exist, returns a zero length List.

    - #### implementors

          List<ClassType> implementors()

      Gets the currently prepared classes which directly implement this interface. The returned list contains only those classes that declared this interface in their "implements" clause.
      Returns:
        a List of `ClassType` objects each mirroring a class implementing this interface. If none exist, returns a zero length List.
