Method Detail

needsMigration

public boolean needsMigration(org.eclipse.emf.common.util.URI resourceUri)

Description copied from interface: DmrToSegmentsMigrator

Checks whether a view model still contains legacy domain model references that need to be migrated to segments.

Specified by:

needsMigration in interface DmrToSegmentsMigrator

Parameters:

resourceUri - The URI of the view model that should be checked.

Returns:

true, if the view model requires a migration, false otherwise.

needsMigration

protected boolean needsMigration(org.eclipse.emf.ecore.resource.Resource resource)

Checks whether a view model still contains legacy domain model references that need to be migrated to segments. The resource must be loaded before handing it into this method.

Parameters:

resource - The loaded resource

Returns:

true, if the view model requires a migration, false otherwise.

performMigration

public void performMigration(org.eclipse.emf.common.util.URI resourceUri,
                             DmrToSegmentsMigrator.PreReplaceProcessor... preReplaceProcessors)
                      throws DmrToSegmentsMigrationException

Description copied from interface: DmrToSegmentsMigrator

Migrates a view model to use segment based DMRs. This replaces all legacy DMRs from the view model and replaces them with segment based DMRs. This is not undoable!

Specified by:

performMigration in interface DmrToSegmentsMigrator

Parameters:

resourceUri - The URI of the view model that should be migrated.

preReplaceProcessors - DmrToSegmentsMigrator.PreReplaceProcessor which are executed just before a legacy dmr is replaced with the corresponding segment dmr. The processors are always executed in the given order

Throws:

DmrToSegmentsMigrationException - if the migration fails

performMigration

protected void performMigration(org.eclipse.emf.ecore.resource.Resource resource,
                                DmrToSegmentsMigrator.PreReplaceProcessor... preReplaceProcessors)
                         throws DmrToSegmentsMigrationException

Migrates all legacy domain model references in the given resource. The resource must be loaded before handing it into this method.

Parameters:

resource - The loaded resource

preReplaceProcessors - The PreReplaceProcessors

Throws:

DmrToSegmentsMigrationException - if the migration fails
