Constructor & Destructor Documentation

CSdpAttributeRequester(RSdpSession &, CSdpAgentEng &)

CSdpAttributeRequester	(	RSdpSession &	aSdpSession,
		CSdpAgentEng &	aParent
	)	[private]

Constructor: Adds this CSdpAttributeRequester to Active Scheduler. Sets parent, and passes client side object for session with SDP server (currently ESock). Sets up cont state member to default 0 length descriptor.

Parameters

RSdpSession & aSdpSession
CSdpAgentEng & aParent

Member Functions Documentation

AttributeRequestL(const TBTDevAddr &, TSdpServRecordHandle, TUint16, CSdpAttrIdMatchList &, const TDesC8 &)

void	AttributeRequestL	(	const TBTDevAddr &	aRemoteDev,
			TSdpServRecordHandle	aHandle,
			TUint16	aMaxAttrByteCount,
			CSdpAttrIdMatchList &	aMatchList,
			const TDesC8 &	aContState
		)

Sets up appropriate member variables, then attempts to connect to remote device. (If connection is made the state machine takes over to make the actual attribute request.)

Parameters

const TBTDevAddr & aRemoteDev
TSdpServRecordHandle aHandle
TUint16 aMaxAttrByteCount
CSdpAttrIdMatchList & aMatchList
const TDesC8 & aContState

ConstructL()

void

ConstructL

(

)

[private]

Currently blank.

DoCancel()

void

DoCancel

(

)

[private, virtual]

Cancels current asynchronous requests. This could be with the Sdp server (currently ESOCK) or if this CSdpRequesterBase is in idle state it cancels the time out timer (set-up to perform a disconnection after a defined length of time).

HandleAttributeResponseL()

void

HandleAttributeResponseL

(

)

[private]

IssueRequestL()

void

IssueRequestL

(

)

[private, virtual]

Requester is now connected. Called down from requester base class. Time to actually issue the request

NewL(RSdpSession &, CSdpAgentEng &)

CSdpAttributeRequester *	NewL	(	RSdpSession &	aSdpSession,
			CSdpAgentEng &	aParent
		)	[static]

Standard NewL method. Note: need to pass the client side object of the SDP service session, and the CSdpA.gentEng parent which is managing this CSdpAttributeRequester active object.

Parameters

RSdpSession & aSdpSession
CSdpAgentEng & aParent

RequestCompleteL()

void

RequestCompleteL

(

)

[private, virtual]

Response parameter format is

         byte count of attr list		TUint16
		Attribute ID & Value		DES
		Continuation State			1 + 0-16 bytes

Reset()

void

Reset

(

)

[private, virtual]

Called when base requester idle timer expires, and when an error is reported Cleans up and makes sure we really are disconnected.

RunError(TInt)

TInt

RunError

(

TInt

aError

)

[private, virtual]

Called automatically when a RunL leaves. Calls appropriate error handling function in the CSdpAgentEng parent.

Parameters

TInt aError

SendAttributeRequest()

void

SendAttributeRequest

(

)
