Class CContactStoreField

class CContactStoreField : public CContactFieldStorage;

Description

Provides access to the binary field data stored in an 8-bit descriptor.

An object of this class can be retrieved using CContactItemField::StoreStorage().

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CContactFieldStorage - Abstract base class for the different types of contact field data storage

• CContactStoreField - Provides access to the binary field data stored in an 8-bit descriptor

Members

Defined in CContactStoreField:

• CContactFieldStorage_Reserved1()
• ExternalizeL()Externalises the field data
• InternalizeL()Internalises the field data
• IsFull()Tests whether the field storage contains data
• RestoreL()Restores the field data
• SetThingL()Sets the field data from an 8-bit descriptor
• SetThingL()Sets the field data from an 8-bit heap descriptor
• SetThingL()Sets the field data from a buffer
• StoreL()Stores the field data
• Thing()Gets a pointer to the binary data stored in the field

Inherited from CBase:

• Delete()Deletes the specified object
• Extension_()Extension function
• operator new()Initialises the object to binary zeroes

virtual TStreamId StoreL(CStreamStore &aStore) const;

Description

Stores the field data.

Parameters

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

Return value

TStreamId The ID of the stream store.

virtual void RestoreL(CStreamStore &aStore, RReadStream &aStream);

Description

Restores the field data.

Parameters

CStreamStore &aStore Reference to the store from which the object is to be restored. RReadStream &aStream Reference to the stream which should be passed to InternalizeL().

IMPORT_C void SetThingL(const TDesC8 &aDes);

Description

Sets the field data from an 8-bit descriptor.

Parameters

const TDesC8 &aDes 8-bit descriptor containing the binary data to copy into the field.

IMPORT_C void SetThingL(const HBufC8 &aDes);

Description

Sets the field data from an 8-bit heap descriptor.

Parameters

const HBufC8 &aDes 8-bit heap descriptor containing the binary data to copy into the field.

IMPORT_C void SetThingL(const CBufBase *aBuf);

Description

Sets the field data from a buffer.

Parameters

const CBufBase *aBuf Buffer containing the binary data to copy into the field.

IMPORT_C HBufC8 *Thing() const;

Description

Gets a pointer to the binary data stored in the field.

Return value

HBufC8 * Pointer to the binary data stored in the field.

virtual void InternalizeL(RReadStream &aStream);

Description

Internalises the field data.

Parameters

RReadStream &aStream Stream from which the the contents of the field should be internalised.

virtual void ExternalizeL(RWriteStream &aStream) const;

Description

Externalises the field data.

Parameters

RWriteStream &aStream Write stream to which the contents of the field should be externalised.

virtual TBool IsFull() const;

Description

Tests whether the field storage contains data.

Return value

TBool True if the field storage contains data, false if not.
