Detailed Description

An interface to report differences between two arbitrary objects.

This interface can be used to report differences between two arbitrary objects by describing a virtual table with three columns. The first column contains the name of the property that is compared, the second column the property value of the one object and the third column the property of the other object.

The rows of this table can have different modes:

• NormalMode The left and right columns show the same property values.
• ConflictMode The left and right columns show conflicting property values.
• AdditionalLeftMode The left column contains a property value that is not available in the right column.
• AdditionalRightMode The right column contains a property value that is not available in the left column.

Example:

// add differences of a contact
const KContacts::Addressee contact1 = ...
const KContacts::Addressee contact2 = ...
 
AbstractDifferencesReporter *reporter = ...
reporter->setPropertyNameTitle( i18n( "Contact fields" ) );
reporter->setLeftPropertyValueTitle( i18n( "Changed Contact" ) );
reporter->setRightPropertyValueTitle( i18n( "Conflicting Contact" ) );
 
// check given name
if ( contact1.givenName() != contact2.givenName() )
  reporter->addProperty( AbstractDifferencesReporter::ConflictMode, i18n( "Given Name" ),
                         contact1.givenName(), contact2.givenName() );
else
  reporter->addProperty( AbstractDifferencesReporter::NormalMode, i18n( "Given Name" ),
                         contact1.givenName(), contact2.givenName() );
 
// check family name
if ( contact1.familyName() != contact2.familyName() )
  reporter->addProperty( AbstractDifferencesReporter::ConflictMode, i18n( "Family Name" ),
                         contact1.givenName(), contact2.givenName() );
else
  reporter->addProperty( AbstractDifferencesReporter::NormalMode, i18n( "Family Name" ),
                         contact1.givenName(), contact2.givenName() );
 
// check emails
const QStringList leftEmails = contact1.emails();
const QStringList rightEmails = contact2.emails();
 
for ( const QString &leftEmail : leftEmails ) {
  if ( rightEmails.contains( leftEmail ) )
    reporter->addProperty( AbstractDifferencesReporter::NormalMode, i18n( "Email" ),
                           leftEmail, leftEmail );
  else
    reporter->addProperty( AbstractDifferencesReporter::AdditionalLeftMode, i18n( "Email" ),
                           leftEmail, QString() );
}
 
for( const QString &rightEmail : rightEmails ) {
  if ( !leftEmails.contains( rightEmail ) )
    reporter->addProperty( AbstractDifferencesReporter::AdditionalRightMode, i18n( "Email" ),
                           QString(), rightEmail );
}
