Detailed Description

The QContactRelationship class describes a one-to-one relationship between a locally-stored contact and another (possibly remote) contact.

Each relationship is uniquely identified by the combination of the first contact id, second contact id, and the relationship type.

A relationship should not contain a second contact which is the same as the first contact. Any local contacts which are referenced in the relationship (that is, any source contact, or any second contact whose manager URI is left empty or whose manager URI references the manager that stores the source contact, and in which the relationship will be saved) should exist.

If any of these requirements are not met, validation of the relationship may fail when attempting to save the relationship in a QContactManager.

See also QContactRelationshipFilter.

Member Type Documentation

enum QContactRelationship::Role

Describes the roles that a contact may take in a relationship.

QContactRelationship::Either2The contact is either the first or second contact in the relationship

Member Function Documentation

QContactRelationship::QContactRelationship ()

Constructs a new relationship

QContactRelationship::QContactRelationship ( const QContactRelationship & other )

Creates a copy of the other relationship

This function was introduced in Qt Mobility 1.0.

QContactRelationship::~QContactRelationship ()

Frees the memory in use by the relationship

QContactId QContactRelationship::first () const

Returns the id of the locally-stored contact which has a relationship of the given type with the second contact

This function was introduced in Qt Mobility 1.0.

See also relationshipType(), second(), and setFirst().

QString QContactRelationship::relationshipType () const

Returns the type of relationship which the source contact has with the destination contacts

This function was introduced in Qt Mobility 1.0.

See also setRelationshipType().

QContactId QContactRelationship::second () const

Returns the id of the contact with which the first contact has a relationship of the given type

This function was introduced in Qt Mobility 1.0.

See also setSecond(), relationshipType(), and first().

void QContactRelationship::setFirst ( const QContactId & firstId )

Sets the id of the first contact in the relationship to firstId. This contact must be stored in the manager in which the relationship is stored, and has a relationship of the specified type with the second contact.

This function was introduced in Qt Mobility 1.0.

See also first().

void QContactRelationship::setRelationshipType ( const QString & relationshipType )

Sets the type of relationship that the source contact has with the destination contacts to relationshipType.

This function was introduced in Qt Mobility 1.0.

See also relationshipType().

void QContactRelationship::setSecond ( const QContactId & secondId )

Sets the second contact in the relationship to secondId. The first contact has a relationship of the specified type with this contact.

This function was introduced in Qt Mobility 1.0.

See also second().

bool QContactRelationship::operator!= ( const QContactRelationship & other ) const

Returns true if this relationship is not equal to other, otherwise returns false.

This function was introduced in Qt Mobility 1.0.

QContactRelationship & QContactRelationship::operator= ( const QContactRelationship & other )

Assigns this relationship to be equal to other

This function was introduced in Qt Mobility 1.0.

bool QContactRelationship::operator== ( const QContactRelationship & other ) const

Returns true if this relationship is equal to the other relationship, otherwise returns false.

This function was introduced in Qt Mobility 1.0.

Member Variable Documentation

const QLatin1Constant QContactRelationship::HasManager

The relationship type which identifies the second contact as being the manager of the first contact

const QLatin1Constant QContactRelationship::HasMember

The relationship type which identifies the first contact as being a group which includes the second contact
