Class Method Details

.all ⇒ Array

An abbreviated list of possible units. These are known combinations of atoms and prefixes. Since units can be combined to create more complex units (and thus an infinite number), a full list can’t be provided.

Returns:

  • (Array) —

    A list of known units

  @all ||= begin
    units = []
    Atom.all.each do |a|

      Unitwise::Prefix.all.each { |p| units << build(a,p) } if a.metric?
    end
    units
  end
end

.search(term) ⇒ Array

Parameters:

  • term (String, Regexp) —

    The term to search for

Returns:

  • (Array) —

    A list of matching units.
