A typical AST view of a MIDP class in an application might look like this:


CompilationUnit

 ImportDeclaration

  Name:javax.microedition.midlet

 ImportDeclaration

  Name:javax.microedition.lcdui

 TypeDeclaration

  ClassOrInterfaceDeclaration(Me)(class)

   ExtendsList

    ClassOrInterfaceType:MIDlet

   ClassOrInterfaceBody

    ClassOrInterfaceBodyDeclaration

     ConstructorDeclaration:(public)

      FormalParameters

    ClassOrInterfaceBodyDeclaration

     MethodDeclaration:(public)

      ResultType

      MethodDeclarator:startApp

       FormalParameters

      Block

    ClassOrInterfaceBodyDeclaration

     MethodDeclaration:(public)

      ResultType

      MethodDeclarator:pauseApp

       FormalParameters

      Block

    ClassOrInterfaceBodyDeclaration

     MethodDeclaration:(public)

      ResultType

      MethodDeclarator:destroyApp

       FormalParameters

        FormalParameter:(package private)

         Type

          PrimitiveType:boolean

         VariableDeclaratorId:unconditional

      Block

This is of course a correct MIDlet class. Bascially, I want to test for the absence of specific items such as ClassType, in this case MIDlet. Other items to check for the absence of are MethodDeclarators such as destroyApp, pauseApp, and startApp.
