Member Functions Documentation

Compare(const CCalEntry &, const CCalEntry &)

TInt	Compare	(	const CCalEntry &	aFirst,
			const CCalEntry &	aSecond
		)	[static]

Wrapper which traps leaving CompareL() , and in leave situation returns that objects are equal since that is a safer interpretation and avoids duplicates in database. In real life CompareL() is not expected to ever leave.

Parameters

const CCalEntry & aFirst	entry
const CCalEntry & aSecond	entry

CompareL(const CCalEntry &, const CCalEntry &)

TInt	CompareL	(	const CCalEntry &	aFirst,
			const CCalEntry &	aSecond
		)	[static]

Helper which allows ordering entries in an array. That is implemented by evaluating GUID and RECURRENCE-ID of the two entries.

Parameters

const CCalEntry & aFirst	entry
const CCalEntry & aSecond	entry

DbStatus()

MESMRCalDbObserver::TDbStatus

DbStatus

(

)

Database status getter.

EntryView()

const CCalEntryView *

EntryView

(

)

const

Entry view accessor. Ownership not transferred.

EntryView()

CCalEntryView *

EntryView

(

)

Entry view accessor. Ownership not transferred.

FetchWithRangeL(RPointerArray< CCalEntry > &, const CalCommon::TCalTimeRange &, TBool)

void	FetchWithRangeL	(	RPointerArray < CCalEntry > &	aCalEntryArray,
			const CalCommon::TCalTimeRange &	aCalTimeRange,
			TBool	aFetchFullCopy = ETrue
		)

CCalEntryView lacks fetch with time range. This method provides such functionality. In case of repeating entries the entire sequence must be within range (but modifying entries are considered separately). If database doesn't have both instance and entry view then this method leaves with KErrNotSupported.

Parameters

RPointerArray < CCalEntry > & aCalEntryArray	fetched entries, caller owns array items
const CalCommon::TCalTimeRange & aCalTimeRange	time range
TBool aFetchFullCopy = ETrue	copy type of calendar entry

InstanceView()

const CCalInstanceView *

InstanceView

(

)

const

Instance view accessor. Ownership not transferred.

InstanceView()

CCalInstanceView *

InstanceView

(

)

Instance view accessor. Ownership not transferred.

IsCompletelyWithinRangeL(const CCalEntry &, const CalCommon::TCalTimeRange &)

TBool	IsCompletelyWithinRangeL	(	const CCalEntry &	aEntry,
			const CalCommon::TCalTimeRange &	aCalTimeRange
		)	[static]

Tests whether given entry fits completely within given time range.

Parameters

const CCalEntry & aEntry	entry to test
const CalCommon::TCalTimeRange & aCalTimeRange	criterion

NotifyProgress()

TBool

NotifyProgress

(

)

[protected]

Progress(TInt)

void

Progress

(

TInt

aPercentageCompleted

)

[protected]

Parameters

TInt aPercentageCompleted

ResetDbL()

void

ResetDbL

(

)

[virtual]

Reset database, causes asynchronous db initialization which is notified through MMRUtilsCalDbObserver interface. Calling this method requires that there are no external open references for the session. The default implementation leaves with KErrNotSupported.

Session()

const CCalSession *

Session

(

)

const

Session accessor. Ownership not transferred.

Session()

CCalSession *

Session

(

)

Session accessor. Ownership not transferred.
