DirSummarySize Property

The total size of the directory contents, excluding file replicas.

Syntax

 hadoopdfs.getDirSummarySize([callback])

Default Value

0

Callback

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 getDirSummarySize([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 setDirSummarySize([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 total size of the directory contents, excluding file replicas.

This property reflects the total size (in bytes) of the directory's contents, calculated recursively.

Unlike DirSummarySpaceUsed, this property's value does not take file replicas into account, and thus should not be interpreted as the actual number of bytes the directory's contents use on disk.

This property is read-only and not available at design time.
