                               message_prefix: '', validator_response_details: nil)

  raise Exceptions::TestSuiteImplementationException.new(
    'Logical Model Validation',
    'Logical model validation not implemented for legacy fhir_validation.'
  )
end

#exclude_message {|message| ... } ⇒ Object

Filter out unwanted validation messages. Any messages for which the block evalutates to a truthy value will be excluded.

Examples:

validator do
  exclude_message { |message| message.type == 'info' }
end

Yield Parameters:

def exclude_message(&block)
  @exclude_message = block if block_given?
  @exclude_message
end

#perform_additional_validation {|resource, profile_url| ... } ⇒ Object

Perform validation steps in addition to FHIR validation.

Examples:

perform_additional_validation do |resource, profile_url|
  if something_is_wrong
    { type: 'error', message: 'something is wrong' }
  else
    { type: 'info', message: 'everything is ok' }
  end
end

Yield Parameters:

  • resource (FHIR::Model)

    the resource being validated

  • profile_url (String)

    the profile the resource is being validated against

Yield Returns:

  • (Array<Hash<Symbol, String>>, Hash<Symbol, String>)

    The block should return a Hash or an Array of Hashes if any validation messages should be added. The Hash must contain two keys: :type and :message. :type can have a value of 'info', 'warning', or 'error'. A type of 'error' means the resource is invalid. :message contains the message string itself.
