Parameters

CPosLmActiveOperation * aActiveOp

ExecuteAsyncStep()

void ExecuteAsyncStep ( ) [private]

ExecuteL()

void ExecuteL ( ) [virtual]

From CPosLmOperation .

Synchronous execution of the operation.

When this function returns, the operation has successfully finished.

ExecuteSyncStep()

void ExecuteSyncStep ( ) [private]

ExecuteSyncStepL()

void ExecuteSyncStepL ( ) [private]

HandleMultiDbSearchDeleted()

void HandleMultiDbSearchDeleted ( )

This function must be called by the CPosLmMultiDbSearch class if it is deleted before the search operation has completed.

IncrementSearchStatus()

void IncrementSearchStatus ( ) [private]

IncrementSearchStep()

void IncrementSearchStep ( ) [private]

NewL(CPosLmMultiDbSearch *, const CPosLmSearchCriteria &, CPosLmMultiDbSortPref *, TBool)

CPosLmMultiDbSearchOperation * NewL ( CPosLmMultiDbSearch * aMultiDbSearch,
const CPosLmSearchCriteria & aCriteria,
CPosLmMultiDbSortPref * aSortPref,
TBool aSearchOnlyPreviousMatches
) [static]

Two-phased constructor.

Parameters

CPosLmMultiDbSearch * aMultiDbSearch A pointer to the multi db search object.
const CPosLmSearchCriteria & aCriteria The search criteria.
CPosLmMultiDbSortPref * aSortPref A pointer to the sort preference object. This class takes ownership.
TBool aSearchOnlyPreviousMatches This flag may be used to perform a search within the results of previous search.

NextStep(TRequestStatus &, TReal32 &)

void NextStep ( TRequestStatus & aStatus,
TReal32 & aProgress
) [virtual]

From CPosLmOperation .

Performs one step of the operation asynchronously.

Parameters

TRequestStatus & aStatus The request status. Will be completed when the step has been performed. The request status will be KRequestPending if the step has not completed. It will be KPosLmOperationNotComplete if the step has completed but more steps are needed before the operation has finished. The request status will be KErrNone if the operation has finished successfully.
TReal32 & aProgress Will be set to the progress of the operation when the step has finished.

OpenDbAndCreateInitOpL()

CPosLmOperation * OpenDbAndCreateInitOpL ( ) [private]

OperationCallBack(TAny *)

TInt OperationCallBack ( TAny * aPtr ) [static]

Parameters

TAny * aPtr
