AddMetadata Method

Adds a metadata item to the Metadata properties.

Syntax

azureblob.addMetadata(name, value, [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){ }

'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

This method adds a metadata item to the Metadata properties. Name specifies the name of the item, and Value specifies the value of the item.

Note that the class will automatically prepend x-ms-meta- to metadata item names (as necessary) when they are submitted to the server. Also note that while metadata item names are case-preserving, they are not case-sensitive.
