TAiwGenericParam Class Reference

class TAiwGenericParam

Generic parameter class for passing data between applications. A generic parameter is a pair of semantic ID and variant value. The semantic ID tells the purpose of the parameter, for example a file name, URL or phone number. The variant value contains the data format and actual value. This class does not implement any consistency checks between the semantic ID and value's data format. So one semantic ID can be expressed as alternative data formats.

Member Functions Documentation

CleanupDestroy(TAny *)

voidCleanupDestroy(TAny *aObj)[private, static]

Callback for operator TCleanupItem().

Parameters

TAny * aObj

CopyLC(const TAiwGenericParam &)

voidCopyLC(const TAiwGenericParam &aParam)[private]

Copies aParam to this parameter. Takes an own copy of the value held in aParam.

Parameters

const TAiwGenericParam & aParam

Destroy()

voidDestroy()[private, inline]

Releases any dynamic data owned by this parameter.

ExternalizeL(RWriteStream &)

voidExternalizeL(RWriteStream &aStream)const [private]

Externalizes this parameter to aStream.

Parameters

RWriteStream & aStream

InternalizeL(RReadStream &)

voidInternalizeL(RReadStream &aStream)[private]

Internalizes this parameter from aStream.

Parameters

RReadStream & aStream

Reset()

voidReset()[inline]

Resets the semantic ID and the value of this parameter.

SemanticId()

TGenericParamId SemanticId()const [inline]

Returns the semantic ID of this parameter.

SetSemanticId(TGenericParamId)

voidSetSemanticId(TGenericParamIdaSemanticId)[inline]

Sets the semantic ID. Possibly set previous ID is overwritten.

Parameters

TGenericParamId aSemanticIdThe semantic ID of the parameter.

Size()

TInt Size()const [private]

Returns the maximum externalized size of this parameter.

Value()

TAiwVariant &Value()[inline]

Returns the value of this parameter.

Value()

const TAiwVariant &Value()const [inline]

Returns the const value of this parameter.

operator TCleanupItem()

operator TCleanupItem()[private]

Returns a cleanup item that will call Destroy to this object when PopAndDestroy'ed.
