Member Functions Documentation

MHFRunError(TInt, RHTTPTransaction, const THTTPEvent &)

IMPORT_C TInt MHFRunError ( TInt aError,
RHTTPTransaction aTransaction,
const THTTPEvent & aEvent
) [virtual]

Called when RunL leaves from a transaction event. This works in the same way as CActve::RunError; return KErrNone if you have handled the error. If you don't completely handle the error, a panic will occur.

Parameters

TInt aError The leave code that RunL left with.
RHTTPTransaction aTransaction The transaction that was being processed.
const THTTPEvent & aEvent The Event that was being processed.

MHFRunL(RHTTPTransaction, const THTTPEvent &)

IMPORT_C void MHFRunL ( RHTTPTransaction aTransaction,
const THTTPEvent & aEvent
) [virtual]

Called when the filter's registration conditions are satisfied for events that occur on a transaction. Any Leaves must be handled by the appropriate MHFRunError. Note that this function is not allowed to leave if called with certain events. THTTPEvent Most Filters will be either a transaction filter or a session event filter. Default implementations of all MHTTPFilterBase functions are provided so filter implementors only have to override the functions they need

Parameters

RHTTPTransaction aTransaction The transaction that the event has occurred on.
const THTTPEvent & aEvent The event that has occurred.

MHFSessionRunError(TInt, const THTTPSessionEvent &)

IMPORT_C TInt MHFSessionRunError ( TInt aError,
const THTTPSessionEvent & aEvent
) [virtual]

Called when MHFRunL leaves from a session event. This works in the same way as CActve::RunError If you don't completely handle the error, a panic will occur.

Parameters

TInt aError The leave code that RunL left with.
const THTTPSessionEvent & aEvent The Event that was being processed.

MHFSessionRunL(const THTTPSessionEvent &)

IMPORT_C void MHFSessionRunL ( const THTTPSessionEvent & aEvent ) [virtual]

Called when the filters registration conditions are satisfied for events that occur on the session. Any leaves must be handled by the appropriate MHFRunError.

Parameters
