Disconnect(TRequestStatus &)

IMPORT_C void

Disconnect

(

TRequestStatus &

aStatus

)

OBEX DISCONNECT operation.

This terminates the OBEX connection, and closes the transport on receiving any response from the server.

Parameters

TRequestStatus & aStatus

Asynchronous status word. On completion, KErrNone on normal disconnection, or KErrDisconnected if the server dropped the transport before sending an OBEX response (which is valid behaviour).

EmptyHeaderSet()

void

EmptyHeaderSet

(

)

[private]

ExtensionInterface(TUid)

IMPORT_C TAny *

ExtensionInterface

(

TUid

aUid

)

Provides additional interfaces for CObexClient.

Parameters

TUid aUid

The UID of the interface that is required.

Get(CObexBaseObject &, TRequestStatus &)

IMPORT_C void	Get	(	CObexBaseObject &	aObject,
			TRequestStatus &	aStatus
		)

OBEX GET operation.

The caller specifies in aObject the headers to send to the server to specify the object to get: normally just a name is expected. If the server can serve the request, the object it returns will be loaded into aObject on completion. All headers returned by the server that are also allowed by the object s header mask will be loaded into the relevant attributes of aObject. Any object body is stored according to the implementation type of the CObexBaseObject passed.

Parameters

CObexBaseObject & aObject	OBEX object to get; on completion, the retrieved object
TRequestStatus & aStatus	Asynchronous status word. On completion, KErrNone if the server passed back an OBEX object, or the appropriate file error if the data file could not be opened

GetPutFinalResponseHeaders()

IMPORT_C const CObexHeaderSet &

GetPutFinalResponseHeaders

(

)

This function can be called following the successful completion of a Put, and will return a reference to a CObexHeaderSet containing all the headers that were contained in the final Put response packet returned from the peer Obex server.

The headers in the header set will be deleted by any subsequent call to CObexClient functions that trigger Obex commands (ie. Connect, Disconnect, Put, Get, SetPath).

The reference should not be retained beyond the end of the lifetime of the CObexClient object.

LastServerResponseCode()

IMPORT_C TObexResponse

LastServerResponseCode

(

)

const

Get last server response code This method returns the last received OBEX response code. The method must not be called prior to a response notification being received by the client application. If the method is called a panic will be raised.

panic: ENoResponseCodeToReturn Panics if the method is called prior to a response being received from the OBEX server.

NewL(TObexProtocolInfo &)

IMPORT_C CObexClient *

NewL

(

TObexTransportInfo &

aObexTransportInfo

)

[static]

TTimeIntervalMicroSeconds32

aTimeOut

)

Sets the Command Idle Time-out.

This function sets the timer period to be observed during the progress of all OBEX commands. If the OBEX server does not respond within the set period the current OBEX command will be completed with an error of KErrIrObexRespTimedOut and the transport will be disconnected.

Setting a time-out value of 0, all OBEX commands will be allowed to continue indefinitely.

aObserver

)

Sets a final packet observer.

This replaces any previous observer. The observer will receive a callback when a final packet for a put or get request begins to be sent and another when the send completes. Although the start and finish callbacks are guaranteed to be in order, no guarantees are made about the ordering with respect to the completion of the put or get request.

This does not transfer ownership.

Parameters

MObexFinalPacketObserver * aObserver

The observer to receive packet process events. This may be NULL.
