“r_link_cnt”の意思

  The r_link_cnt attribute has double usage one is for folder and another is for virtual document. FOr folder is store the number of object linked to folder. In case of virtual document it store the number of components in virtual document.
  

 

   A document is said to be a virtual document, if the value “r_is_virtual_doc” attribute is set to “1″.
If the value is set to “0″ then it is not a virtual document unless “r_link_cnt” attribute of the object is greater than “1″ and the object is not of type “dm_folder” or “dm_cabinet”.

    If r_link_cnt is > 0 the object is a virtual document or a folder/cabinet.
  “r_link_cnt” will never have a value of 1, because the parent of the virtual document is also considered a child. So if you add one component, r_link_cnt=2. If you add a second component, r_link_cnt=3, and so on.”r_link_cnt” attribute applies to dm_folder/dm_cabinet, indicating how many objects are linked to this folder.
