Detailed Description

An Akonadi Tag.

Definition at line 25 of file tag.h.

Member Enumeration Documentation

CreateOption

enum Akonadi::Tag::CreateOption

Describes the options that can be passed to access attributes.

Enumerator
AddIfMissing	Creates the attribute if it is missing.
DontCreate	Does not create an attribute if it is missing (default)

Definition at line 114 of file tag.h.

Constructor & Destructor Documentation

Tag()

Tag::Tag ( const QString &  name )

explicit

Creates a PLAIN tag.

Definition at line 36 of file tag.cpp.

Member Function Documentation

addAttribute()

void Tag::addAttribute

(

Attribute *

attribute

)

Adds an attribute to the entity.

If an attribute of the same type name already exists, it is deleted and replaced with the new one.

Parameters

attribute

The new attribute.

Note

The entity takes the ownership of the attribute.

Definition at line 98 of file tag.cpp.

attribute() [1/3]

template<typename T >

const T * Akonadi::Tag::attribute

inline

Returns the attribute of the requested type or 0 if it is not available.

Definition at line 225 of file tag.h.

attribute() [2/3]

const Attribute * Tag::attribute

(

const QByteArray &

name

)

const

Returns the attribute of the given type name if available, 0 otherwise.

Definition at line 123 of file tag.cpp.

attribute() [3/3]

template<typename T >

T * Akonadi::Tag::attribute ( CreateOption  option = DontCreate )

inline

Returns the attribute of the requested type.

If the entity has no attribute of that type yet, a new one is created and added to the entity.

Parameters

option

The create options.

Definition at line 206 of file tag.h.

attributes()

Attribute::List Tag::attributes

(

)

const

Returns a list of all attributes of the entity.

Definition at line 113 of file tag.cpp.

clearAttributes()

void Tag::clearAttributes

(

)

Removes and deletes all attributes of the entity.

Definition at line 118 of file tag.cpp.

genericTag()

Tag Tag::genericTag ( const QString &  name )

static

Returns a GENERIC tag with the given name and a valid gid.

Definition at line 219 of file tag.cpp.

hasAttribute() [1/2]

template<typename T >

bool Akonadi::Tag::hasAttribute

inline

Returns whether the entity has an attribute of the requested type.

Definition at line 246 of file tag.h.

hasAttribute() [2/2]

bool Tag::hasAttribute

(

const QByteArray &

name

)

const

Returns true if the entity has an attribute of the given type name, false otherwise.

Definition at line 108 of file tag.cpp.

id()

Tag::Id Tag::id

(

)

const

Returns the unique identifier of the tag.

Definition at line 139 of file tag.cpp.

isImmutable()

bool Tag::isImmutable

(

)

const

Returns true if the tag is immutable (cannot be modified after creation).

Note that the immutability does not affect the attributes.

Definition at line 207 of file tag.cpp.

removeAttribute() [1/2]

template<typename T >

void Akonadi::Tag::removeAttribute

inline

Removes and deletes the attribute of the requested type.

Definition at line 239 of file tag.h.

removeAttribute() [2/2]

void Tag::removeAttribute

(

const QByteArray &

name

)

Removes and deletes the attribute of the given type name.

Definition at line 103 of file tag.cpp.

setId()

void Tag::setId

(

Tag::Id

identifier

)

Sets the unique identifier of the tag.

Definition at line 134 of file tag.cpp.

url()

QUrl Tag::url

(

)

const

Returns the url of the tag.

Definition at line 87 of file tag.cpp.

Member Data Documentation

GENERIC

const char Akonadi::Tag::GENERIC = "GENERIC"

static

The GENERIC type has the following properties:

• mutable
• gid is RFC 4122 compatible
• no hierarchy (no parent)

GENERIC tags are general purpose tags, that are used, if you can change tag name.

Definition at line 49 of file tag.h.

PLAIN

const char Akonadi::Tag::PLAIN = "PLAIN"

static

The PLAIN type has the following properties:

• gid == displayName
• immutable
• no hierarchy (no parent)

PLAIN tags are general purpose tags that are easy to map by backends.

Definition at line 39 of file tag.h.
