Method Detail

refresh

public ExtensionComponentSet refresh()
                              throws ExtensionRefreshException

Description copied from class: ExtensionFinder

Rebuilds the internal index, if any, so that future ExtensionFinder.find(Class, Hudson) calls will discover components newly added to PluginManager.uberClassLoader.

The point of the refresh operation is not to disrupt instances of already loaded ExtensionComponents, and only instantiate those that are new. Otherwise this will break the singleton semantics of various objects, such as Descriptors.

The behaviour is undefined if ExtensionFinder.isRefreshable() is returning false.

Specified by:

refresh in class ExtensionFinder

Returns:

never null

Throws:

ExtensionRefreshException

find

public <T> Collection<ExtensionComponent<T>> find(Class<T> type,
                                                  Hudson jenkins)

Description copied from class: ExtensionFinder

Discover extensions of the given type.

This method is called only once per the given type after all the plugins are loaded, so implementations need not worry about caching.

This method should return all the known components at the time of the call, including those that are discovered later via ExtensionFinder.refresh(), even though those components are separately returned in ExtensionComponentSet.

Specified by:

find in class ExtensionFinder

Type Parameters:

T - The type of the extension points. This is not bound to ExtensionPoint because of Descriptor, which by itself doesn't implement ExtensionPoint for a historical reason.

jenkins - Jenkins whose behalf this extension finder is performing lookup.

Returns:

Can be empty but never null.
