    - #### isCompatibleWith

          public boolean isCompatibleWith​(ClassNode classNode)

      Compares this generics type with the provided class node. If the provided class node is compatible with the generics specification, returns true. Otherwise, returns false. The check is complete, meaning that nested generics are also checked.
      Returns:
        if `classNode` is or is not compatible with this generics specification
