Member Function Documentation

addToRelation()

template<typename T >

static bool Akonadi::Server::Entity::addToRelation ( qint64  leftId, qint64  rightId  )

inlinestatic

Adds an entry to a n:m relation table (specified by the template parameter).

Parameters

leftId	Identifier of the left part of the relation.
rightId	Identifier of the right part of the relation.

Definition at line 78 of file entity.h.

clearRelation()

template<typename T >

static bool Akonadi::Server::Entity::clearRelation ( qint64  id, RelationSide  side = Left  )

inlinestatic

Clears all entries from a n:m relation table (specified by the given template parameter).

Parameters

id	Identifier on the relation side.
side	The side of the relation.

Definition at line 103 of file entity.h.

count()

template<typename T >

static int Akonadi::Server::Entity::count ( const QString &  column, const QVariant &  value  )

inlinestatic

Returns the number of records having value in column.

Parameters

column	The name of the key column.
value	The value used to identify the record.

Definition at line 50 of file entity.h.

relatesTo()

template<typename T >

static bool Akonadi::Server::Entity::relatesTo ( qint64  leftId, qint64  rightId  )

inlinestatic

Checks whether an entry in a n:m relation table exists.

Parameters

leftId	Identifier of the left part of the relation.
rightId	Identifier of the right part of the relation.

Definition at line 68 of file entity.h.

remove()

template<typename T >

static bool Akonadi::Server::Entity::remove ( const QString &  column, const QVariant &  value  )

inlinestatic

Deletes all records having value in column.

Definition at line 58 of file entity.h.

removeFromRelation()

template<typename T >

static bool Akonadi::Server::Entity::removeFromRelation ( qint64  leftId, qint64  rightId  )

inlinestatic

Removes an entry from a n:m relation table (specified by the template parameter).

Parameters

leftId	Identifier of the left part of the relation.
rightId	Identifier of the right part of the relation.
