CLiwServiceIfBase Class Reference

class CLiwServiceIfBase : public CBase

This is the base service interface to access providers that offer base services.

This interface needs to be implemented by all the LIW providers. Base service providers should inherit from this class directly. Menu service providers should inherit from CLiwServiceIfMenu .

HandleServiceCmdL(const TInt &, const CLiwGenericParamList &, CLiwGenericParamList &, TUint, const MLiwNotifyCallback *)

void	HandleServiceCmdL	(	const TInt &	aCmdId,
			const CLiwGenericParamList &	aInParamList,
			CLiwGenericParamList &	aOutParamList,
			TUint	aCmdOptions = 0,
			const MLiwNotifyCallback *	aCallback = NULL
		)	[pure virtual]

Executes generic service commands included in criteria.

leave: KErrArgument Callback is missing when required.

leave: KErrNotSupported No provider supports service.

Parameters

const TInt & aCmdId	Command to be executed.
const CLiwGenericParamList & aInParamList	Input parameters, can be an empty list.
CLiwGenericParamList & aOutParamList	Output parameters, can be an empty list.
TUint aCmdOptions = 0	Options for the command, see KLiwOpt* in LiwCommon.hrh.
const MLiwNotifyCallback * aCallback = NULL	Callback for asynchronous command handling, parameter checking, etc.

HandleServiceCmdL(const TDesC8 &, const CLiwGenericParamList &, CLiwGenericParamList &, TUint, const MLiwNotifyCallback *)

void	HandleServiceCmdL	(	const TDesC8 &	aCmdName,

			CLiwGenericParamList &	aOutParamList,
			TUint	aCmdOptions = 0,
			const MLiwNotifyCallback *	aCallback = NULL
		)	[inline]

Executes generic service command

leave: KErrArgument Callback is missing when required.

leave: KErrNotSupported No provider supports service.

Parameters

const TDesC8 & aCmdName	The service command to be executed.
const CLiwGenericParamList & aInParamList	Input parameters, can be an empty list.
CLiwGenericParamList & aOutParamList	Output parameters, can be an empty list.
TUint aCmdOptions = 0	Options for the command, see KLiwOpt* in LiwCommon.hrh.

InitialiseL(MLiwNotifyCallback &, const RCriteriaArray &)

void	InitialiseL	(	MLiwNotifyCallback &	aFrameworkCallback,
			const RCriteriaArray &	aInterest
		)	[pure virtual]

Called by the LIW framework to initialise provider with necessary information from the Service Handler. This method is called when the consumer makes the attach operation.

Parameters

MLiwNotifyCallback & aFrameworkCallback	Framework provided callback for provider to send events to framework.
const RCriteriaArray & aInterest	List of criteria items which invoked the provider.
