Constructor Details

#initialize(factory, inflector, terms, *args) ⇒ Isomorphism

Default constructor.

Parameters:

• factory (Isomorphic::Factory::AbstractFactory) —

  the Isomorphic factory

• inflector (Isomorphic::Inflector::AbstractInflector) —

  the Isomorphic inflector

• terms (Array<Object>) —

  the inflectable terms

• args (Array<Object>) —

  the arguments for the isomorphism

Raises:

• (Isomorphic::InflectorError) —

  if an inflectable term is invalid

# File 'lib/isomorphic/lens.rb', line 324

def initialize(factory, inflector, terms, *args)
  super(factory, inflector)

  @terms = terms
  @args = args

  @method_name = inflector.isomorphism(terms)
end
