Modifier and Type	Interface	Description
`static interface`	`DmrToSegmentsMigrator.PreReplaceProcessor`	Processor that is executed after segments have been generated for the new segment based dmr but before the legacy dmr is replaced in the model.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`needsMigration(org.eclipse.emf.common.util.URI resourceUri)`	Checks whether a view model still contains legacy domain model references that need to be migrated to segments.
`void`	`performMigration(org.eclipse.emf.common.util.URI resourceUri, DmrToSegmentsMigrator.PreReplaceProcessor... preReplaceProcessors)`	Migrates a view model to use segment based DMRs.

- Method Detail
  - needsMigration
```
boolean needsMigration(org.eclipse.emf.common.util.URI resourceUri)
```
    Checks whether a view model still contains legacy domain model references that need to be migrated to segments.
    
    Parameters:
    
    resourceUri - The URI of the view model that should be checked.
    
    Returns:
    
    true, if the view model requires a migration, false otherwise.
  - performMigration
```
void performMigration(org.eclipse.emf.common.util.URI resourceUri,
                      DmrToSegmentsMigrator.PreReplaceProcessor... preReplaceProcessors)
               throws DmrToSegmentsMigrationException
```
    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!
    
    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
