module Vedeu
# 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)
#
class RefreshGroup
include Vedeu::Common
# @param name [String] The name of the group to be refreshed.
# @return [Array|Vedeu::Error::ModelNotFound] A collection of the names of
# interfaces refreshed, or an exception when the group was not found.
