Diagnostic

Diagnostic controller base class.

class Diagnostic extends \Hazaar\Controller\Action

This controller provides a common fallback endpoint for diagnostic-style responses and supports multiple response formats (JSON, XML, HTML, text, and Hazaar dump output). It is typically used by internal diagnostics and error-handling flows that need format-aware output from a shared source.

The class also tracks caller context and response code state so subclasses can generate consistent diagnostic payloads across output types.

Properties

code

HTTP status code used by generated diagnostic responses.

protected int $code = 204

Defaults to 204 No Content.

caller

protected array $caller

Methods

__default

Executes the diagnostic run process.

public __default(string $controllerName, string $actionName): Response

This method determines the appropriate response type based on the presence of a response type method or the existence of a 'run' method. If neither is found, it defaults to an HTML response. The response is then wrapped in the appropriate Response object if it is not already an instance of Response.

Parameters

Parameter	Type	Description
$controllerName	string
$actionName	string

setCaller

public setCaller(array $caller): void

Parameters

Parameter	Type	Description
$caller	array

setResponseType

Sets the response type for the diagnostic controller.

public setResponseType(ResponseType $type): void

Parameters

Parameter	Type	Description
$type	ResponseType	the type of response to be returned

json

Returns a JSON response with an error message.

public json(): void

xml

Generates an XML-RPC response.

public xml(): void

This method creates a SimpleXMLElement with a root element xml and adds a child element data with the content 'NO CONTENT'. It then returns this XML structure wrapped in a Response\XML object.

html

Generates an HTML response with a predefined message.

public html(): void

text

Returns a text response with the content 'NO CONTENT' and the specified status code.

public text(): void

hazaar

Outputs a diagnostic dump and terminates the script.

public hazaar(): void

This method sets the HTTP response code to the value of the $code property, outputs a diagnostic message, dumps a placeholder string 'NO CONTENT', prints a backtrace, and then exits the script.
