CMsvSearchSortOperation Constructor

Destructor.

Second phase construction

Implements cancellation of an outstanding request.

This function is called as part of the active object's Cancel() .

It must call the appropriate cancel function offered by the active object's asynchronous service provider. The asynchronous service provider's cancel is expected to act immediately.

DoCancel() must not wait for event completion; this is handled by Cancel() .

CActive::Cancel

Gets the TMsvId of a single index entry object at a time. This function is used when getting the results using iterative mechanism.

Gets one index entry object at a time. This function is used when getting the results using iterative mechanism.

After the completion of asynchronous function RequestL() , this function provides the query Id corresponding to a particular search-sort query.

Returns the count of search-sort results, without returning the actual search-sort results.

After the completion of asynchronous function RequestL() , this function provides a list of index entry Id objects (TMsvId).

After the completion of asynchronous function RequestL() , this function provides a list of index entry objects ( TMsvEntry ).

Allocates and constructs a CMsvSearchSortOperation object.

Search-sort operation is performed on a specified folder (e.g, on INBOX, SENT-ITEMS, DRAFT, OUTBOX or any user created folder).

Getting Search-sort results for specified QueryId.

Handles an active object's request completion event.

A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.

The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.

Before calling this active object's RunL() function, the active scheduler has:

1. decided that this is the highest priority active object with a completed request

2. marked this active object's request as complete (i.e. the request is no longer outstanding)

RunL() runs under a trap harness in the active scheduler. If it leaves, then the active scheduler calls RunError() to handle the leave.

Note that once the active scheduler's Start() function has been called, all user code is run under one of the program's active object's RunL() or RunError() functions.

CActiveScheduler::Start CActiveScheduler::Error CActiveScheduler::WaitForAnyRequest TRAPD

Unmarks the query listed in search-sort cache. The unmarked queries are preferred over marked queries for being disposed from the search-sort cache when the search-sort cache reaches a maximum limit
