Transfer Event

Fired while the article text gets transferred (to or from the NewsServer ).

Syntax

snntp.on('Transfer', [callback])

Callback

The 'callback' is called when the 'Transfer' event is emited.

function(e){ }

The argument 'e' has the following properties:

e.direction
e.bytesTransferred
e.percentDone
e.text (buffer)
e.EOL

Remarks

One or more Transfer events are fired during article retrieval. The Text parameter contains the portion of article data being retrieved.

The BytesTransferred parameter contains the number of bytes transferred since the beginning of the article, including header bytes.

One or more Transfer events are also fired during article posting. Articles consist of ArticleText and an optional AttachedFile. The BytesTransferred parameter shows the number of bytes sent starting from the beginning of ArticleText and/or AttachedFile.

The Transfer event is fired for every line of the article. For complete lines, there is no terminating newline at the end of the Text parameter, and EOL is True. The EOL parameter is False when a line is broken (usually for being too long).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
