PHP tao_helpers_File::truePath方法代码示例

 /**
  * It is sometimes necessary to identify the link between assessmentItemRefs described in a QTI Test definition and the resources
  * describing items in IMS Manifest file. This utility method helps you to achieve this.
  * 
  * The method will return an array describing the IMS Manifest resources that were found in an IMS Manifest file on basis of
  * the assessmentItemRefs found in an AssessmentTest definition. The keys of the arrays are assessmentItemRef identifiers and
  * values are IMS Manifest Resources. 
  * 
  * If an IMS Manifest Resource cannot be found for a given assessmentItemRef, the value in the returned array will be false.
  * 
  * @param XmlDocument $test A QTI Test Definition.
  * @param taoQtiTest_models_classes_ManifestParser $manifestParser A Manifest Parser.
  * @param string $basePath The base path of the folder the IMS archive is exposed as a file system component.
  * @return array An array containing two arrays (items and dependencies) where keys are identifiers and values are oat\taoQtiItem\model\qti\Resource objects or false.
