nsIFeedProcessor 编辑

toolkit/components/feeds/public/nsIFeedProcessor.idlScriptable This interface parses RSS or Atom feeds, triggering callbacks based on their contents during and after the processing. 1.0 66 Introduced Gecko 1.8.1 Inherits from: nsIStreamListener Last changed in Gecko 1.8.1 (Firefox 2 / Thunderbird 2 / SeaMonkey 1.1)

Implemented by: @mozilla.org/feed-processor;1. To create an instance, use:

var feedProcessor = Components.classes["@mozilla.org/feed-processor;1"]
                   .createInstance(Components.interfaces.nsIFeedProcessor);

Method overview

void parseAsync(in nsIRequestObserver requestObserver, in nsIURI uri);

void parseFromStream(in nsIInputStream stream, in nsIURI uri);

void parseFromString(in AString str, in nsIURI uri);

Attributes

Attribute	Type	Description
listener	nsIFeedResultListener	The feed result listener that will respond to feed events.

Methods

parseAsync()

Parses a feed asynchronously. The caller must then call the processor's nsIStreamListener methods to drive the parsing process. You must not call any of the other parsing methods on the nsIFeedProcessor interface during an asynchronous parse.

 void parseAsync(
   in nsIRequestObserver requestObserver,
   in nsIURI uri
 );

Parameters

requestObserver

The observer to be notified when parsing starts and stops. This can be null.

uri

The base URI against which any URIs in the feed are resolved.

parseFromStream()

Parses a feed from an nsIInputStream.

 void parseFromStream(
   in nsIInputStream stream,
   in nsIURI uri
 );

Parameters

stream

Pointer to the nsIInputStream from which to read and parse the feed.

uri

The base URI against which any URIs in the feed are resolved.

parseFromString()

Parses a feed from an AString.

 void parseFromString(
   in AString str,
   in nsIURI uri
 );

Parameters

str

The string to parse as a feed.

uri

The base URI against which any URIs in the feed are resolved.
