#member(member_name, type: nil, default: nil, optional: false, transform_value: nil) ⇒ Object

Parameters:

  • member_name (String)
  • type (Array<Class>, Class) (defaults to: nil)
  • default (Object) (defaults to: nil)
  • optional (TrueClass, FalseClass) (defaults to: false) —

    When true, omits tag rather than rendering an empty tag on nil

  • transform_value (Proc) (defaults to: nil) —

    A Proc which is called with the input value to perform type conversion.
