- All Implemented Interfaces:
    `GroovydocHolder<AnnotatedNode>`, `NodeMetaDataHandler`, `org.objectweb.asm.Opcodes`
  Enclosing class:
    WideningCategories

      public static class WideningCategories.LowestUpperBoundClassNode
      extends ClassNode

  This `ClassNode` specialization is used when the lowest upper bound of two types cannot be represented by an existing type. For example, if B extends A, C extends A and both C and B implement a common interface not implemented by A, then we use this class to represent the bound. At compile time, some classes like `AsmClassGenerator` need to know about a real class node, so we compute a "compile time" node which will be used to return a name and a type class.

          public LowestUpperBoundClassNode​(String name,
                                           ClassNode upper,
                                           ClassNode... interfaces)

  - ### Method Detail

    - #### getLubName

          public String getLubName()

    - #### getName

          public String getName()

      Overrides:
        `getName` in class `ClassNode`

    - #### getTypeClass

          public Class getTypeClass()

      Description copied from class: `ClassNode`
      Returns the concrete class this classnode relates to. However, this method is inherently unsafe as it may return null depending on the compile phase you are using. AST transformations should never use this method directly, but rather obtain a new class node using `ClassNode.getPlainNodeReference()`.
      Overrides:
        `getTypeClass` in class `ClassNode`
      Returns:
        the class this classnode relates to. May return null.

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `ClassNode`

    - #### getText

          public String getText()

      Overrides:
        `getText` in class `ClassNode`

    - #### getPlainNodeReference

          public ClassNode getPlainNodeReference()

      Overrides:
        `getPlainNodeReference` in class `ClassNode`
