Member Functions Documentation

ConstructL(const RArray< TItemId > *, const TMdEIntRange *)

voidConstructL(const RArray< TItemId > *aRelationIds,
const TMdEIntRange *aParameterRange
)[private]

Second-phase constructor. Creates two LogicConditions as children of this relation condition and creates range condition for parameter. Ownership of the parameter stays with caller.

Parameters

const RArray< TItemId > * aRelationIdsThe relation IDs which an relation must match.
const TMdEIntRange * aParameterRangeparameter range conditions

Guid(TInt64 &, TInt64 &)

IMPORT_C TBoolGuid(TInt64 &aGuidHigh,
TInt64 &aGuidLow
)const

Gets the GUID which a relation must match.

Parameters

TInt64 & aGuidHighreference where GuidHigh will be stored
TInt64 & aGuidLowreference where GuidLow will be stored

InternalQueryOptimizationFlags(TUint32 &)

TUint32 InternalQueryOptimizationFlags(TUint32 &aFlags)

Get possible query's internal optimization flags from condition.

Parameters

TUint32 & aFlags

LastModifiedDateRange(TMdETimeRange &)

IMPORT_C TBoolLastModifiedDateRange(TMdETimeRange &aLastModifiedDateRange)const

Gets the last modified date range which a relation must match.

Parameters

TMdETimeRange & aLastModifiedDateRangereference where last modified date range will be stored

LeftL()

IMPORT_C CMdELogicCondition &LeftL()

Returns the conditions for the object on the left side of the relation.

TRelationConditionSideaSide = ERelationConditionSideEither,
const CMdERelationDef *aRelationDef = NULL,
const TMdEIntRange *aParameterRange = NULL
)[static]

Parameters
