Methods summary

`public`	# `__construct( mixed $body = null, integer\|ICanBoogie\HTTP\Status $status = Status::OK, ICanBoogie\HTTP\Headers\|array $headers = [] )` Initializes the $body, $header, $date and $status properties. Initializes the $body, $header, $date and $status properties. Parameters `$body` The body of the response. `$status` The status code of the response. `$headers` The initial header fields of the response.
`public`	# `__clone( )` Clones the `ICanBoogie\HTTP\Response::$headers` and $status properties. Clones the `ICanBoogie\HTTP\Response::$headers` and $status properties.
`public string`	# `__toString( )` Renders the response as an HTTP string. Renders the response as an HTTP string. Returns string
`public`	# `__invoke( )` Issues the HTTP response. Issues the HTTP response. `ICanBoogie\HTTP\Response::finalize()` is invoked to finalize the headers (a cloned actually) and the body. `ICanBoogie\HTTP\Response::send_headers()` is invoked to send the headers and `ICanBoogie\HTTP\Response::send_body()` is invoked to send the body, if the body is not `null`. The body is not send in the following instances: The finalized body is `null`. The status is not ok.
`protected`	# `finalize( ICanBoogie\HTTP\Headers & $headers, mixed & $body )` Finalize the body. Finalize the body. Subclasses might want to override this method if they wish to alter the header or the body before the response is sent or transformed into a string. Parameters `$headers` Reference to the final header. `$body` Reference to the final body.

`protected`	# `assert_body_is_valid( $body )` Asserts that the a body is valid. Asserts that the a body is valid. Parameters `$body` Throws UnexpectedValueException if the specified body doesn't meet the requirements.
