Overview

Takes care of registering validations for a media type. It allows for nested schemes and registers each one so it can be looked up at a later time.

Constructor Details

#initialize(media_type, registry = {}, scheme = Scheme.new, &block) ⇒ Validations

Creates a new stack of validations

Parameters:

  • media_type (Constructable) —

    a Constructable media type

  • registry (Hash) (defaults to: {}) —

    the registry reference, or nil if top level

  • scheme (Scheme) (defaults to: Scheme.new) —

    the current scheme or nil if top level

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *arguments, &block) ⇒ Object

def method_missing(method_name, *arguments, &block)
  if scheme.respond_to?(method_name)
    return scheme.send(method_name, *arguments, &block)
  end

  super
end

Instance Method Details

#find(media_type, default = -> { Scheme::NotStrict.new }) ⇒ Scheme

Looks up the validations for Constructable

Parameters:

  • media_type (String, Constructable)
  • default (lambda) (defaults to: -> { Scheme::NotStrict.new }) —

    the lambda if nothing can be found

Returns:

  • (Scheme) —

    the scheme for the given media_type
