Detailed Description

Service Handler implementation. This class is used to resolve and load service provider plugins. This class also allows listing of service providers

This class is a service handler capable of returning instances of services. Current assumptions for this class are as follows: -Service is registered in the service db -Client DLL name is known -Ownership of instantiated service object is returned to the owner -Service class should make all Javascript accessible methods as public slots

getInterface ( T **, const QString &, const ServiceInterfaceInfo &, bool, SecSession * )

void	getInterface	(	T **	aInterface,
			const QString &	aServiceName,
			const ServiceInterfaceInfo &	aInterfaceInfo,
			bool	aRefCounted,
			SecSession *	aSecSession
		)	[inline]

Creates an instance of a service and return interface pointer

Parameters
aServiceName	Name of the service provider
aInterfaceInfo	Interface info
aRefCounted	true the underlying service object is reference counted. false the underlying service object is not reference counted and the object is owned by service handler
aSecSession	Security Session (not owned). If NULL then that means no security check will be done.

Return Value: IServiceBase* interface pointer to the service if the service is found, NULL if service is not found

getServiceProviders ( SecSession * )

QStringList

getServiceProviders

(

SecSession *

aSecSession = NULL

)

Gets a list of all services from the service resolver

Return Value: QStringList of all services

getServiceVersion ( const QString & )

QString

getServiceVersion

(

const QString &

aServiceName

)

Gets version of a service provider from the service resolver

Parameters
aServiceName	Name of the service provider

Return Value: QString service version
