CSenServiceManager Class Reference

class CSenServiceManager : public CActive

CSenServiceManager class offers API for accessing and managing WebServicesFramework (WSF) service and identity related data. The class is designed using abstract factory pattern: it only offers a instance (pointer) to the actual implementation class meeting this interface. Typically, service consumers use of CSenServiceManager to register service or identity based data, which is required for accessing some invocable, possibly remote service. The class is meant for both default frameworks offered by WSF and for any custom plug-in service invocation framework implementation. The default frameworks are: 1) Identity Based Web Services Framework (ID-WSF). 2) Basic Web Services Framework. For Basic Web Service consumer, the only applicable operations are Identity data managing methods. These can be used to make connection specific Basic Authentication (BASIC-AUTH) credentials available without later end-user interaction. Otherwise required authentication info will be requested via notifier dialog prompts. ID-WSF consumer has to use the CSenServiceManager methods to register authentication service description and identity provider (which are the same service in ID-WSF) and finally associate some actual service (contract to a WSP) to this IDP.

The current client-server framework implementation of CSenServiceManager is synchronous, although class inherits CActive for future extensions. So, the class instance will not be an active object handled by ActiveScheduler, and it does not have implementation in RunL() or DoCancel() methods.

AssociateServiceL(const TDesC8 &, const TDesC8 &)

TInt	AssociateServiceL	(	const TDesC8 &	aURI,
			const TDesC8 &	aProviderID
		)	[pure virtual]

Consumer applications use this method to associate some pre-registered service to certain (registered) identity provider. The association adds the service ID (contract of the service that trusts this identity provider) into WSF identity database. In ID-WSF, consumers typically associate authentication service description with some identity provider. This way the ID-WSF framework can find the identity provider by using the contract of the service as a search pattern (for e.g. liberty AS contract).

Parameters

const TDesC8 & aURI	either the contract or the endpoint identifying some service
const TDesC8 & aProviderID	the ID of an identity provider

CredentialsL(const TDesC8 &, RCredentialArray &, RCredentialPropertiesArray &)

TInt	CredentialsL	(	const TDesC8 &	aEndpoint,

		)	[pure virtual]

Consumer applications use this method for finding Credentials. IdentityProvider or Username and Password are given either via IdentityProviderL() callback or UsernameL() and Password() callbacks from MSenAuthenticationProvider (which can be given through specialized NewL or NewLC methods).

Error codes: KErrNotFound Web Services framework couldn't find the Credentials using given Endpoint. KErrSenNoPermission Given IdentityProvider or Username and Password did not match for IdentityProvider which is related to found Credential(s). Other error codes are system-wide Symbian error codes.

TInt	DissociateServiceL	(	const TDesC8 &	aServiceID,
			const TDesC8 &	aProviderID
		)	[pure virtual]

Dissociate a service from an identity provider.

Parameters

const TDesC8 & aServiceID	the contract or endpoint of a service
const TDesC8 & aProviderID	the id of an identity provider

InterfaceByUid(TUid)

TAny *

InterfaceByUid

(

TUid

aUID

)

[pure virtual]

This method provides an interface which is identified by unique ID (UID). Currently, there is only one supported interface: KSenInterfaceUidInternalServiceManager => MSenInternalServiceManager

Parameters

TUid aUID

Register an identity provider for the current active identity. It is required for both Basic Web Service and ID-WSF consumers that endpoint is defined in identity provider instance to make this data accessible later on while creating a service connection. A possible work-around for this would be to unregister such conflicting identity provider using this particular ProviderID, but this solution is not recommended. Instead, separate providers, locating in different endpoints, SHOULD always use different ProviderIDs. Other error codes are system-wide Symbian error codes.

Parameters

CSenIdentityProvider & aProvider

an identity provider to be registered

RegisterServiceDescriptionL(MSenServiceDescription &)

TInt

RegisterServiceDescriptionL

(

MSenServiceDescription &

aSD

)

[pure virtual]

Used by consumer applications to register new service to WSF The service could not otherwise be discovered while creating a service connection. ID-WSF Authentication Service is an example of this kind of remote service. The Basic Web Service consumer does not need to and cannot register any service related data. In service description, the default framework ID is "ID-WSF", through which frameworks performing the actual registration are looked up. For any custom framework plug-in, the framework ID must be separately set. For ID-WSF service descriptions it is mandatory to set both contract and endpoint. Calling the method performs one of the following: 1. It registers a new service description 2. It updates an existing service description with matching contract and endpoint.

Parameters

MSenServiceDescription & aSD

a service description to be registered

RemoveCredentialsL(const MSenServiceDescription &, const CSenIdentityProvider &)

TInt	RemoveCredentialsL	(	const MSenServiceDescription &	aPattern,
			const CSenIdentityProvider &	aIdP
		)	[pure virtual]

ServiceDescriptionsL(const TDesC8 &, RServiceDescriptionArray &)

TInt	ServiceDescriptionsL	(	const TDesC8 &	aURI,
			RServiceDescriptionArray &	aList
		)	[pure virtual]

Consumers use this to find services with matching URI (contract or endpoint) of the service. ID-WSF consumers typically use the service type (contract) they are interested on. Contract is typically some URN and most endpoints are URLs. The Basic Web Service descriptions are not written into WSF database, so they cannot be searched using this method.

Parameters

const TDesC8 & aURI
RServiceDescriptionArray & aList	an array with 0 or more service descriptions which are already registered to WSF. The ownership of the array is passed to the caller so before the array goes out of scope in the client, the caller must call RPointerArray::ResetAndDestroy() on the array to free any entries.

ServiceDescriptionsL(MSenServiceDescription &, RServiceDescriptionArray &)

TInt	ServiceDescriptionsL	(	MSenServiceDescription &	aSD,
			RServiceDescriptionArray &	aList
		)	[pure virtual]

Consumers use this to find services with matching service description. The service description may include specific contract or endpoint of the service as a searching criteria. Contract is typically some URN and most endpoints are URLs. The Basic Web Service descriptions are not written into WSF database, so they cannot be searched using this method.

Parameters

MSenServiceDescription & aSD	a service description specifying search pattern (which includes contract, URI or both) used to find matching service descriptions.
RServiceDescriptionArray & aList	an array with 0 or more ServiceDescriptions which are already registered to WSF. The ownership of the array is passed to the caller so before the array goes out of scope in the client, the caller must call RPointerArray::ResetAndDestroy() on the array to free any entries.
