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.

Parameters
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.

Parameters
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.

Return Value: 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.

Parameters
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.

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

Return Value: The ID of the stream store.
