-
- * An argument handler for use in fields that have a many to one relationship
- * with the table(s) to the left. This adds a bunch of options that are
- * reasonably common with this type of relationship.
- * Definition terms:
- * - numeric: If true, the field will be considered numeric. Probably should
- * always be set TRUE as views_handler_argument_string has many to one
- * capabilities.
- * - zero is null: If true, a 0 will be handled as empty, so for example
- * a default argument can be provided or a summary can be shown.
- *
- * @ingroup views_argument_handlers
