- ## Method Details

  - ### addError

    protected void addError(String message, ASTNode node, SourceUnit source)
    Adds a new syntax error to the source unit and then continues.
    Parameters:
      `message` - the message
      `node` - the node for the error report
      `source` - the source unit for the error report

  - ### getTargetAnnotationList

    protected List<AnnotationNode> getTargetAnnotationList(AnnotationNode collector, AnnotationNode aliasAnnotationUsage, SourceUnit source)
    Returns a list of AnnotationNodes for the value attribute of the given AnnotationNode.
    Parameters:
      `collector` - the node containing the value member with the list
      `source` - the source unit for error reporting
    Returns:
      a list of string constants

  - ### visit

    public List<AnnotationNode> visit(AnnotationNode collector, AnnotationNode aliasAnnotationUsage, AnnotatedNode aliasAnnotated, SourceUnit source)
    Implementation method of the alias annotation processor. This method will get the list of annotations we aliased from the collector and adds it to aliasAnnotationUsage. The method will also map all members from aliasAnnotationUsage to the aliased nodes. Should a member stay unmapped, we will add an error. Further processing of those members is done by the annotations.
    Parameters:
      `collector` - reference to the annotation with `AnnotationCollector`
      `aliasAnnotationUsage` - reference to the place of usage of the alias
      `aliasAnnotated` - reference to the node that has been annotated by the alias
      `source` - source unit for error reporting
    Returns:
      list of the new AnnotationNodes
