Class AllowEmbeddedHTMLPlugIn

java.lang.Object
  org.clapper.curn.plugins.AllowEmbeddedHTMLPlugIn

All Implemented Interfaces:

FeedConfigItemPlugIn, MainConfigItemPlugIn, PlugIn, PostFeedParsePlugIn

public class AllowEmbeddedHTMLPlugIn
extends java.lang.Object
implements MainConfigItemPlugIn, FeedConfigItemPlugIn, PostFeedParsePlugIn

The AllowEmbeddedHTMLPlugIn handles stripping (or not stripping) embedded HTML from parsed RSS data. It intercepts the following configuration parameters:

Section	Parameter	Meaning
[curn]	AllowEmbeddedHTML	The default (global) setting for all feeds. If not specified, the default value is "false".
[Feedxxx]	AllowEmbeddedHTML	The setting for a specific feed. If not specified, the global default is used.

Note that enabling embedded HTML for a feed might not be sufficient, since embedded HTML can be disabled on a per-output handler basis, as well.

Constructor Detail

AllowEmbeddedHTMLPlugIn

public AllowEmbeddedHTMLPlugIn()

Default constructor (required).

Method Detail

getPlugInName

public java.lang.String getPlugInName()

Get a displayable name for the plug-in.

Specified by:

getPlugInName in interface PlugIn

Returns:

the name

getPlugInSortKey

public java.lang.String getPlugInSortKey()

Get the sort key for this plug-in.

Specified by:

getPlugInSortKey in interface PlugIn

Returns:

the sort key string.

initPlugIn

public void initPlugIn()
                throws CurnException

Initialize the plug-in. This method is called before any of the plug-in methods are called.

Specified by:

initPlugIn in interface PlugIn

Throws:

CurnException - on error

runMainConfigItemPlugIn

public void runMainConfigItemPlugIn(java.lang.String sectionName,
                                    java.lang.String paramName,
                                    CurnConfig config)
                             throws CurnException

Called immediately after curn has read and processed a configuration item in the main [curn] configuration section. All configuration items are passed, one by one, to each loaded plug-in. If a plug-in class is not interested in a particular configuration item, this method should simply return without doing anything. Note that some configuration items may simply be variable assignment; there's no real way to distinguish a variable assignment from a blessed configuration item.

Specified by:

runMainConfigItemPlugIn in interface MainConfigItemPlugIn

Parameters:

sectionName - the name of the configuration section where the item was found

paramName - the name of the parameter

config - the CurnConfig object

Throws:

CurnException - on error

runFeedConfigItemPlugIn

public boolean runFeedConfigItemPlugIn(java.lang.String sectionName,
                                       java.lang.String paramName,
                                       CurnConfig config,
                                       FeedInfo feedInfo)
                                throws CurnException

Called immediately after curn has read and processed a configuration item in a "feed" configuration section. All configuration items are passed, one by one, to each loaded plug-in. If a plug-in class is not interested in a particular configuration item, this method should simply return without doing anything. Note that some configuration items may simply be variable assignment; there's no real way to distinguish a variable assignment from a blessed configuration item.

Specified by:

runFeedConfigItemPlugIn in interface FeedConfigItemPlugIn

Parameters:

sectionName - the name of the configuration section where the item was found

paramName - the name of the parameter

config - the active configuration

feedInfo - partially complete FeedInfo object for the feed. The URL is guaranteed to be present, but no other fields are.

Returns:

true to continue processing the feed, false to skip it

Throws:

CurnException - on error

runPostFeedParsePlugIn

public boolean runPostFeedParsePlugIn(FeedInfo feedInfo,
                                      RSSChannel channel)
                               throws CurnException

Called immediately after a feed is parsed, but before it is otherwise processed. This method can return false to signal curn that the feed should be skipped. For instance, a plug-in that filters on the parsed feed data could use this method to weed out non-matching feeds before they are downloaded. Similarly, a plug-in that edits the parsed data (removing or editing individual items, for instance) could use method to do so.

Specified by:

runPostFeedParsePlugIn in interface PostFeedParsePlugIn

Parameters:

feedInfo - the FeedInfo object for the feed that has been downloaded and parsed.

channel - the parsed channel data

Returns:

true if curn should continue to process the feed, false to skip the feed. A return value of false aborts all further processing on the feed. In particular, curn will not pass the feed along to other plug-ins that have yet to be notified of this event.

Throws:

CurnException - on error
