Hi,
in the importer module in GeoServer I have a need to determine which files
compose a certain store or reader.
This is needed because I need to perform some work on the files I'm given
(transformations) and only if they succeed, decide to move the files to
a final place (their stable location in the data dir).
For data stores, maybe we could have a sub-interface of ResourceInfo?
FileResourceInfo, that would have an extra method such as
/**
* Returns all files making up this resource
*/
List<File> getFiles();
For coverage readers there is already a getSource() method, which
for file based readers returns a File object, or a String/URL that
can be turned into a File.
In AbstractGridCoverage2DReader there is also getInfo, which returns a
ServiceInfo...
maybe we could have a FileServiceInfo there, with the same extension
as ResourceInfo, or a mixin interface FileInfo that can be applied to
both.
I guess I like best the mixin one, seems like something that's also
easy to backport to the stable series (as a pure addition, with no breakage
of existing interfaces)
Opinions?
Cheers
Andrea
