# Refresh an interface, or collection of interfaces belonging to a
# group.

# The interfaces will be refreshed in z-index order, meaning that
# interfaces with a lower z-index will be drawn first. This means
# overlapping interfaces will be drawn as specified.
#
# @example
# Vedeu.trigger(:_refresh_group_, group_name)
#
# @api private
#
class Refresh
include Vedeu::Common
# @macro param_name
# @return [Array|Vedeu::Error::ModelNotFound] A collection of
# the names of interfaces refreshed, or an exception when the
# group was not found.
