Public Instance Methods

make_set(*value_or_set_or_array) click to toggle source

Return a set containing the input item or list of items. If the input is a set or an array, it is returned. In all cases, the constructed set is a flattened version of the input and any nil elements are removed by strip_set_nils. Note that this behavior effectively converts nil to [].

# File lib/aquarium/utils/set_utils.rb, line 11
def make_set *value_or_set_or_array
  strip_set_nils(convert_to_set(*value_or_set_or_array))
end
