The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getDirSummaryDirCount([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setDirSummaryDirCount([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
The number of subdirectories within the directory.
This property reflects the number of subdirectories contained within the directory, calculated recursively. Note that this count will always include the directory itself; i.e., this property would return 1 for a directory with no subfolders.
This property is read-only and not available at design time.
