Destructor

AddSearchFlag() Adds the search specific flag specifying the field on which the search operation is to be performed.

AddSortFlag() Adds the sort specific flag specifying the field on which the result would be sorted.

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

DoCopySortDataL() copies the sort data. This is obtained by calling the basemtm getextension method.

DoGetEntryForAllIdL() Gets TMsvEntry for all Id's in RArray asynchronously

FindInHeaderBodyL() This function performs the actual search, sort or search-sort operation. Steps: 1) Initializes partlist flags. These flags are used in the client mtm code to identify different message parts and other information. 2) Checks mtm type for each TMsvId specified in the array. If the mtm is found, continues with the operation else registers the particular mtm type and continues. 3) Load message. This sets the context to the message 4) If it is a search operation, than it matches each query option specified in the query table If all the options are succesfully matched, adds it to resultant list 5) If sorting is specified than copies the sort data only when the last of the query table condition is successfully matched 6) In case of sorting, call the pure virtual Find method to copy only the sort data. 7) In case of search by attachment types, restores the attachment manager and identifies the attachment.

GetResultAsInvalidTMsvIdL() Returns a list of TMsvIds that do not satisfy the search criteria and are not part of the final result set

GetResultAsTMsvIdL() Returns a list of TMsvIds and the Sort field data

GetResultAsTMsvIdWithSortFieldL() Returns a list of TMsvIds and the Sort field data

GetResultAsTmsvEntryL()

InitializePartList() Adds flags to parts variable before performing the actual operation. This method gets called once and the flag value persists until all the TMsvIds are exhausted.

ProcessQuery Initialzes the search sort operation. This copies the array of ids and initialzes different parameters for the operartion

RemoveSearchFlag() Removes the search partlist and resets that bit. The next query option could be on different field.

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

SearchSortOnHeaderBodyL Initialzes the search sort operation. This copies the array of ids and initialzes different parameters for the operartion
