Constructor Detail

MongoPersistentEntityIndexResolver

public MongoPersistentEntityIndexResolver(MongoMappingContext mappingContext)

Create new MongoPersistentEntityIndexResolver.

Parameters:

mappingContext - must not be null.

Method Detail

resolveIndexForClass

public List<MongoPersistentEntityIndexResolver.IndexDefinitionHolder> resolveIndexForClass(Class<?> type)

Find and create IndexDefinitions for properties of given type. IndexDefinitions are created for properties and types with Indexed, CompoundIndexes or GeoSpatialIndexed.

Returns:

Empty Iterable in case no IndexDefinition could be resolved for type.

resolveIndexForEntity

public List<MongoPersistentEntityIndexResolver.IndexDefinitionHolder> resolveIndexForEntity(MongoPersistentEntity<?> root)

Resolve the IndexDefinitions for given root entity by traversing MongoPersistentProperty scanning for index annotations Indexed, CompoundIndex and GeospatialIndex. The given root has therefore to be annotated with Document.

Parameters:

root - must not be null.

Returns:

List of MongoPersistentEntityIndexResolver.IndexDefinitionHolder. Will never be null.

Throws:

IllegalArgumentException - in case of missing Document annotation marking root entities.

createCompoundIndexDefinitions

protected List<MongoPersistentEntityIndexResolver.IndexDefinitionHolder> createCompoundIndexDefinitions(String dotPath,
                                                                                                        String fallbackCollection,
                                                                                                        Class<?> type)

Create IndexDefinition wrapped in MongoPersistentEntityIndexResolver.IndexDefinitionHolder for CompoundIndexes of given type.

Parameters:

dotPath - The properties "dot" path representation from its document root.

fallbackCollection -

type -

Returns:

createCompoundIndexDefinition

protected MongoPersistentEntityIndexResolver.IndexDefinitionHolder createCompoundIndexDefinition(String dotPath,
                                                                                                 String fallbackCollection,
                                                                                                 CompoundIndex index)

createIndexDefinition

protected MongoPersistentEntityIndexResolver.IndexDefinitionHolder createIndexDefinition(String dotPath,
                                                                                         String fallbackCollection,
                                                                                         MongoPersistentProperty persitentProperty)

Creates IndexDefinition wrapped in MongoPersistentEntityIndexResolver.IndexDefinitionHolder out of Indexed for given MongoPersistentProperty.

Parameters:

dotPath - The properties "dot" path representation from its document root.

collection -

persitentProperty -

Returns:

createGeoSpatialIndexDefinition

protected MongoPersistentEntityIndexResolver.IndexDefinitionHolder createGeoSpatialIndexDefinition(String dotPath,
                                                                                                   String fallbackCollection,
                                                                                                   MongoPersistentProperty persistentProperty)
