    • validate

      public List<Throwable> validate(DbControl dc)
      Validate the files in this file set. This method will invoke extensions for the "net.sf.basedb.core.filehandler.validator" extension point and let them handle the actual validation. This method will not throw any errors that have been caused by the validation process. Errors are returned as a list of Throwable:s and is also reported by setting the FileSetMember.isValid() and FileSetMember.getErrorMessage() properties for each file.

      Note! PermissionDeniedException:s are not considered validation errors. They are ignored and doesn't change the validation status.

      InvalidRelationException is a less severe type of exception and can be used by a validator when the actual file it is validating is valid but a dependent file is not. For example, a valid CEL file has been attached to a raw bioassay, but it doesn't match the CDF file attached to the array design. If a validator throws this exception the member status will be set to invalid, but metadata is not reset.

      Parameters:
      dc - The DbControl to use in the validation process
      Returns:
      A list of validation errors, if everything is successful the list is empty
