CSdpRequesterBase Class Reference
| class CSdpRequesterBase : public CActive |
Constructor & Destructor Documentation
CSdpRequesterBase(RSdpSession &, CSdpAgentEng &)
Constructor: This is where ESock session and the CSdpAgentEng parent are provided. Other member variables are given default values.
~CSdpRequesterBase()
Destructor: Deletes buffer for responses. Ensures we are disconnected.
Member Functions Documentation
ConnectL()
Ask to connect to remote device address currently set-up in this active object. Note that we ensure that we are disconnected first...we could be connected to a different device.
Disconnect()
| void | Disconnect | ( | ) | [private] |
Bring down a currently existing connection.
DoCancel()
| void | DoCancel | ( | ) | [protected, virtual] |
Cancels current asynchronous request. This will be either an SDP query being performed through ESock or, if this CSdpRequesterBase is in the idle state, a timer (set-up to perform a disconnection after a defined length of time).
IssueRequestL()
| void | IssueRequestL | ( | ) | [protected, pure virtual] |
NewRequestL(const TBTDevAddr &)
| void | NewRequestL | ( | const TBTDevAddr & | aRemDev | ) | [protected] |
Attempts to connect to the remote device. This is the first thing to do on receipt of a new request.
RequestCompleteL()
| void | RequestCompleteL | ( | ) | [protected, pure virtual] |
Reset()
| void | Reset | ( | ) | [protected, virtual] |
RetrieveResponseL()
| void | RetrieveResponseL | ( | ) | [protected] |
The initial response to a search or attribute request contains a buffer size. To obtain the actual result, the response buffer has to be made big enough, and then have the actual result copied into it from the server. RetrieveResponseL() does just this.
RunL()
| void | RunL | ( | ) | [private, virtual] |
Runs state machine. If no errors then:
state disconnected -> state requesting
The request was stored before
connection, and now is made.
state requesting -> state idle.
The request has completed. See
if any further requests come in
over a brief period.
state idle -> state disconnected
if idle state interrupted by new request,
this is notional - the RunL is immediately
called again to set state to requesting
and issue the actual request.
