  Returns:
    The WireFeed this was created from, or null

### getFeedType

    `encoding` - the charset encoding of the feed.

### getUri

    public String getUri()

  Returns the feed URI.

  How the feed URI maps to a concrete feed type (RSS or Atom) depends on the concrete feed type. This is explained in detail in Rome documentation, Feed and entry URI mapping.

  The returned URI is a normalized URI as specified in RFC 2396bis.

  Note: The URI is the unique identifier, in the RSS 2.0/atom case this is the GUID, for RSS 1.0 this is the URI attribute of the item. The Link is the URL that the item is accessible under, the URI is the permanent identifier which the aggregator should use to reference this item. Often the URI will use some standardized identifier scheme such as DOI's so that items can be identified even if they appear in multiple feeds with different "links" (they might be on different hosting platforms but be the same item). Also, though rare, there could be multiple items with the same link but a different URI and associated metadata which need to be treated as distinct entities. In the RSS 1.0 case the URI must be a valid RDF URI reference.

  Specified by:
    `getUri` in interface `SyndFeed`
  Returns:
    the feed URI, null if none.

### setUri

    public void setUri(String uri)
