public interface IRepositoryInfo
Provides methods for obtaining information for server repository disk space allocation. Could be used generically to obtain usage information for any mount point, however, this interface is prepared for the API to provide methods to obtain usage info for the server filesystem containing the image uploads. For the OMERO server base this is /OMERO. For this implementation it could be anything e.g. /Data1.
Methods that fail or cannot execute on the server will throw an InternalException. This would not be normal and would indicate some server or disk failure.
