Constructor Details

FeedEntryMessageSource

public FeedEntryMessageSource(URL feedUrl,
 String metadataKey)

Creates a FeedEntryMessageSource that will use a HttpURLFeedFetcher to read feeds from the given URL. If the feed URL has a protocol other than http*, consider providing a custom implementation of the Resource via the alternate constructor.

Parameters:

feedUrl - The URL.

metadataKey - The metadata key.

FeedEntryMessageSource

public FeedEntryMessageSource(Resource feedResource,
 String metadataKey)

Creates a FeedEntryMessageSource that will read feeds from the given Resource.

Parameters:

feedResource - the Resource to use.

metadataKey - the metadata key.

Since:

5.0

Method Details

setMetadataStore

public void setMetadataStore(MetadataStore metadataStore)

setSyndFeedInput

public void setSyndFeedInput(com.rometools.rome.io.SyndFeedInput syndFeedInput)

Specify a parser for Feed XML documents.

Parameters:

syndFeedInput - the SyndFeedInput to use.

Since:

5.0

setPreserveWireFeed

public void setPreserveWireFeed(boolean preserveWireFeed)

Specify a flag to indication if WireFeed should be preserved in the target SyndFeed.

Parameters:

preserveWireFeed - the boolean flag.

Since:

5.0

• SyndFeedInput.setPreserveWireFeed(boolean)

getComponentType

public String getComponentType()

onInit

protected void onInit()

Overrides:

onInit in class AbstractExpressionEvaluator

doReceive

protected @Nullable com.rometools.rome.feed.synd.SyndEntry doReceive()

Description copied from class: AbstractMessageSource

Subclasses must implement this method. Typically, the returned value will be the payload of type T, but the returned value may also be a Message instance whose payload is of type T; also can be AbstractIntegrationMessageBuilder which is used for additional headers population.

Specified by:

doReceive in class AbstractMessageSource<com.rometools.rome.feed.synd.SyndEntry>

Returns:

The value returned.

toString

public String toString()

Overrides:

toString in class Object
