Detailed Description

Abstract base class for the different types of contact field data storage.

CContactTextField, CContactStoreField, CContactAgentField, CContactDateField and CContactNumberField are all derived from this class.

A pointer to the base class can be obtained by calling CContactItemField::Storage(). Pointers to the derived classes can be retrieved by calling CContactItemField::TextStorage(), CContactItemField::StoreStorage() etc.

Member Function Documentation

ExternalizeL ( RWriteStream & )

void

ExternalizeL

(

RWriteStream &

aStream

)

const [pure virtual]

Externalises the field data.

Parameter	Description
aStream	Write stream to which the contents of the field should be externalised.

InternalizeL ( RReadStream & )

void

InternalizeL

(

RReadStream &

aStream

)

[pure virtual]

Internalises the field data.

Parameter	Description
aStream	Stream from which the the contents of the field should be internalised.

IsFull ( )

TBool

IsFull

(

)

const [pure virtual]

Tests whether the field storage contains data.

Returns: True if the field storage contains data, false if not.

RestoreL ( CStreamStore &, RReadStream & )

void	RestoreL	(	CStreamStore &	aStore,
			RReadStream &	aStream
		)	[pure virtual]

Restores the field data.

Parameter	Description
aStore	Reference to the store from which the object is to be restored.
aStream	Reference to the stream which should be passed to InternalizeL().

StoreL ( CStreamStore & )

TStreamId

StoreL

(

CStreamStore &

aStore

)

const [pure virtual]

Stores the field data.

Parameter	Description
aStore	Reference to the stream store to which the field data is written.

Returns: The ID of the stream store.
