Initializing the service

Every service must have an init() method which tells TYPO3 CMS whether the service is available or not. This is where you should test the connection to whatever remote application you are connecting to. If that test connection fails, the init() method should return false. Otherwise it should return true.

If your connector has no risk of failing (for example, because it operates locally and is not dependent on anything special), you must still implement the init() method and have it return true all the time.

The init() method of the base connector class (\Cobweb\Svconnector\Service\ConnectorBase) performs some initializations, including reading its own configuration. So in your own service you should always call the parent method and - if reading a specific configuration - you should store it in its own member variable or merge it with the base class configuration. The code should look something like:

protected function init() {
        parent::init();
        $localConfiguration = unserialize($GLOBALS['TYPO3_CONF_VARS']['EXT']['extConf'][$this->extKey]);
        $this->extConfiguration = array_merge($this->extConfiguration, $localConfiguration);
}

Obviously you can ignore this if your extension has no configuration.
