    - #### getSourceUnit

          protected SourceUnit getSourceUnit()

      Specified by:
        `getSourceUnit` in class `ClassCodeVisitorSupport`

    - #### type

          protected abstract ClassNode type()

    - #### createCondition

          protected abstract Expression createCondition()

      Subclasses should implement this method to set the condition of the interruption statement

    - #### getErrorMessage

    - #### setupTransform

          protected void setupTransform(AnnotationNode node)

    - #### visit

          public void visit(ASTNode[] nodes,
                   SourceUnit source)

      Description copied from interface: `ASTTransformation`
      The method is invoked when an AST Transformation is active. For local transformations, it is invoked once each time the local annotation is encountered. For global transformations, it is invoked once for every source unit, which is typically a source file.
      Specified by:
        `visit` in interface `ASTTransformation`
      Parameters:
        `nodes` - The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For global transformations it is usually safe to ignore this parameter.
        `source` - The source unit being compiled. The source unit may contain several classes. For global transformations, information about the AST can be retrieved from this object.

    - #### getBooleanAnnotationParameter

          protected static boolean getBooleanAnnotationParameter(AnnotationNode node,
                                              java.lang.String parameterName,
                                              boolean defaultValue)

    - #### getClassAnnotationParameter

          protected static ClassNode getClassAnnotationParameter(AnnotationNode node,
                                              java.lang.String parameterName,
                                              ClassNode defaultValue)

    - #### internalError

          protected static void internalError(java.lang.String message)

    - #### createInterruptStatement

          protected Statement createInterruptStatement()

      Returns:
        Returns the interruption check statement.

    - #### wrapBlock

          protected final Statement wrapBlock(Statement statement)

      Takes a statement and wraps it into a block statement which first element is the interruption check statement.
      Parameters:
        `statement` - the statement to be wrapped
      Returns:
        a `block statement` which first element is for checking interruption, and the second one the statement to be wrapped.
