                      configurationProvider(_:didCompleteWith:)

Delegate method called by ConfigurationLoader.loadConfiguration(userInputs:) when configuration data is found, or when the queue has been exhausted with no data found.

Declaration

Swift

func configurationProvider(_ provider: ConfigurationProviding?, didCompleteWith result: Bool)

Parameters

`provider`	The configuration provider in the loader’s queue that obtained configuration data, or the last item in the queue if no data was found. Optional to support case where an empty queue was submitted.
`result`	The result of the returned provider’s attempt to retrieve configuration data (see `ConfigurationProviding.provideConfiguration(input:)`). `true` if data was found; otherwise, `false`.


                      
                      
                      configurationProvider(_:didEncounter:)

Delegate method called by ConfigurationLoader when an error is encountered during the call to a provider’s ConfigurationProviding.provideConfiguration(input:).

Declaration

Swift

func configurationProvider(_ provider: ConfigurationProviding, didEncounter error: Error)

Parameters

`provider`	The configuration provider in the loader’s queue that encountered the error.
`error`	The `Error` encountered by the configuration provider.


                      
                      
                      configurationProvider(_:requestedInput:completionHandler:)

Delegate method called by ConfigurationLoader.loadConfiguration(userInputs:) after its queue’s input requirements have been gathered. This method will only be called if input is needed and was not supplied during ConfigurationLoader.loadConfiguration(userInputs:).

Example of input object for a DiscoveryServiceConfigurationProvider; note the empty value for the emailAddress key:

 var input = ["com.sap.configuration.provider.discoveryservice": ["emailAddress": ""]]

Declaration

Swift

func configurationProvider(_ loader: ConfigurationLoader, requestedInput: [String : [String : Any]], completionHandler: @escaping (_ input: [String : [String : Any]]) -> Void)
