GetReparseRuleByMask Method

Retrieves the reparse rule associated with the specified file mask.

Syntax

cbfilter.getReparseRuleByMask(mask, productGUID, [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 reparse rule identified by Mask and associated with the application identified by ProductGUID. If such a reparse rule is found, this method returns its reparse mask (see AddReparseRule); otherwise, it returns empty string.

The Mask parameter must be the file mask of an existing rule.

In most cases, the value passed for the ProductGUID parameter should be the same one that was used to call the Initialize method.

Note: The methods and properties related to rule management are not intended to be used from multiple threads at once. Applications that wish to use said methods and properties from multiple threads (such as, e.g., during the AfterFilterAttachToVolume and AfterFilterDetachFromVolume events) are responsible for employing proper thread synchronization techniques to ensure that manipulation and enumeration of the rule lists occurs in a thread-safe manner.
