CContactItemViewDef Class Reference

class CContactItemViewDef : public CBase

A view definition for a contact item.

When reading or opening a contact item using the CContactDatabase class, a view definition may be specified to indicate which field data should be retrieved. See for instance CContactDatabase::ReadContactL().

A view definition for a contact item contains an array of field types, a use (CContactItemViewDef::TUse) and a mode (CContactItemViewDef::TMode). The use indicates whether the field types contained in the view definition should be included in or excluded from the view. The mode indicates whether fields with the hidden attribute should be included or excluded.

AddL(TFieldType)

IMPORT_C void

AddL

(

TFieldType

aFieldType

)

Appends a field type to the view definition's array of field types.

Parameters

TFieldType aFieldType

The field type to append to the array of field types.

Contains(const CContactItem &)

IMPORT_C TBool

Contains

(

const CContactItem &

aItem

)

Tests whether a contact item complies with the view definition.

This indicates whether or not the item will be included in the view.

Parameters

const CContactItem & aItem

The contact item to test.

Count()

TInt

Count

(

)

const [inline]

Gets the number of field types in the view definition.

ExternalizeL(RWriteStream &)

IMPORT_C void

ExternalizeL

(

RWriteStream &

aStream

)

const

Externalises the item view definition to a write stream. The presence of this function means that the standard templated operator<<() (defined in s32strm.h) is available to externalise objects of this class.

Parameters

RWriteStream & aStream

Stream to which the item view definition should be externalised.

Find(const CContentType &)

IMPORT_C TInt

Find

(

const CContentType &

aContentType

)

const

Searches the view definition for any field type contained in the specified content type.

Parameters

const CContentType & aContentType

Content type containing the field types to search for.

Find(TFieldType)

IMPORT_C TInt

Find

(

TFieldType

aFieldType

)

const

Searches the view definition for the specified field type.

Parameters

TFieldType aFieldType

The field type to search for.

InternalizeL(RReadStream &)

IMPORT_C void

InternalizeL

(

RReadStream &

aStream

)

Internalises the item view definition from a read stream. The presence of this function means that the standard templated operator>>() (defined in s32strm.h) is available to internalise objects of this class.

Parameters

RReadStream & aStream

Stream from which the item view definition should be internalised.

MatchesAll()

IMPORT_C TBool

MatchesAll

(

)

const

Tests whether the view definition contains a field type with the value KUidContactFieldMatchAll.

If this is the case, all fields in the contact item are retrieved, regardless of the other field types specified in the view definition.

Mode()

TMode

Mode

(

)

const [inline]

Gets the view definition's mode.

NewL(TUse, TMode)

IMPORT_C CContactItemViewDef *	NewL	(	TUse	aUse,
			TMode	aMode
		)	[static]

Allocates and constructs a new CContactItemViewDef, with a use and a mode.

Parameters

TUse aUse	Specifies whether to include or exclude specified fields.
TMode aMode	Specifies whether to include or exclude hidden fields.

NewLC(TUse, TMode)

IMPORT_C CContactItemViewDef *	NewLC	(	TUse	aUse,
			TMode	aMode
		)	[static]

Allocates and constructs a new CContactItemViewDef, specifying a use and a mode, leaving the object on the cleanup stack.

Parameters

TUse aUse	Specifies whether to include or exclude specified fields.
TMode aMode	Specifies whether to include or exclude hidden fields.

NewLC(RReadStream &)

CContactItemViewDef *

NewLC

(

RReadStream &

aStream

)

[static]

Allocates and constructs a new CContactItemViewDef based on a RReadStream, specifying a use and a mode, leaving the object on the cleanup stack.

Parameters

RReadStream & aStream

RReadStream containing object to internalize.

Remove(TFieldType)

IMPORT_C void

Remove

(

TFieldType

aFieldType

)

Removes a field type, identified by its UID.

Parameters

TFieldType aFieldType

The field type to remove from the list. This must be present in the CContactItemViewDef object, or the function raises a panic.

Remove(TInt)

IMPORT_C void

Remove

(

TInt

aIndex

)

Removes a field type, identified by its index into the array of field types.

Parameters

TInt aIndex

The index of the element to delete. The position is relative to zero. This value must not be negative and must not be greater than the number of elements currently in the list, or the function raises a panic.

Reset()

void

Reset

(

)

[inline]

Deletes all field types from the view definition's field type array.

SetMode(TMode)

void

SetMode

(

TMode

aMode

)

[inline]

Sets the view definition's mode.

Parameters

TMode aMode

The new TMode setting.

SetUse(TUse)

void

SetUse

(

TUse

aUse

)

[inline]

Sets the view definition's use.

Parameters

TUse aUse

The new TUse setting.

Use()

TUse

Use

(

)

const [inline]

Gets the view definition's use.

operator[](TInt)

TUid

operator[]

(

TInt

aIndex

)

const [inline]

Gets the field type located at a specified index position within the field type array.

Parameters

TInt aIndex

The position of the field type in the array, relative to zero. It must be non-negative and less than the number of objects in the array otherwise the function raises a panic.
