如何更新现有的协作者

Question

我有一个遍历文件夹树的程序，以便根据员工及其位置的列表来设置文件夹树的安全性。

首先，我将删除所有安全性，然后再添加用户和组。当用户被重新添加为合作者时，这产生了数千封电子邮件，并且有很多讨厌的邮件给我！

因此，现在我试图找到一种更新协作者的方法，而不是删除/添加。我正在做的事情是从文件夹中建立一个协作者列表。然后，我在列表中寻找特定用户。如果找不到它们，我添加它们。如果找到它们，我需要将其安全性从“编辑器”更新为“ Co_Owner”。

有人知道怎么做吗？参见下面的代码。...

//  Loop through the property's sub-folders
for (final BoxFolder propertySubfolder : boxService.getSubFolders( propertyFolder ))
{
    out.format( "  %s%n", propertySubfolder.getInfo().getName() );

// Capture a list of all existing collaborators for later...
List<BoxCollaboration.Info > listOfCollaborators = new ArrayList<BoxCollaboration.Info >();

for( final BoxCollaboration.Info collaboration : propertySubfolder.getCollaborations() )
{
    //  Loop through existing collaborators and remove any groups so we can add them later with the appropriate access
    if( collaboration.getAccessibleBy() != null )
    {
        String collabName = collaboration.getAccessibleBy().getName();
        if( StringUtils.containsIgnoreCase( listOfGroupEditors.toString(), collabName ) )
        {
            out.println( "  Removing: " + collabName );
            collaboration.getResource().delete();
        }
        else
        {
            // Add all collaborators in this subfolder to a list for checking if we need to add collaborators later
            listOfCollaborators.add( collaboration );
        }
    }
}

int index;
BoxCollaboration.Info aCollaboration;
// Add the regional directory as a co_owner
if( regionalDirector != null )
{
    index = findCollaborator( regionalDirector, listOfCollaborators );
    if( index == -1 )
    {
        out.println( "  Adding regional director: " + regionalDirector.getInfo().getName() );
        propertySubfolder.collaborate( regionalDirector, BoxCollaboration.Role.CO_OWNER );
    }
    else
    {
        aCollaboration = listOfCollaborators.get( index );
        aCollaboration.setRole( BoxCollaboration.Role.CO_OWNER );
        // now what?
    }
}
