Iterable<? extends MutableAsset> discover(Collection<? extends AssetType> types)
                                          throws Exception

Returns all the assets of given types which are available through the bound service.

This method is invoked only if the RepositoryService declares an Importer for at least one of the given types. Implementations do not need to perform this check, and may in fact ignore the input entirely if their RepositoryService supports only one type.

Parameters:

types - the asset types

Returns:

the assets

Throws:

Exception - if the assets cannot be discovered
