GetFileTagSize Method

Retrieves the size of a raw file tag attached to the specified vault item.

Syntax

cbvault.getFileTagSize(fileName, tagId, [callback])

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 this 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.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method retrieves the size of the binary data held by a raw file tag, identified by TagId, attached to the vault item (file, directory, or alternate stream) specified by FileName. If there isn't a raw file tag with the specified TagId attached to the specified vault item, this method returns 0 as the tag size.

The value passed for FileName must be a vault-local absolute path. The value passed for TagId must be in the range 0x0001 to 0xCFFF (inclusive).

Please refer to the File Tags topic for more information.

Note: This method can only be called when Active is true.
