public interface AssociationVisitationStrategy
```
Strategy for walking associations as defined by the Hibernate metamodel. Is essentially a callback listener for interesting events while walking a metamodel graph
start() and finish() are called at the start and at the finish of the process.
Walking might start with an entity or a collection depending on where the walker is asked to start. When starting with an entity, startingEntity(org.hibernate.persister.walking.spi.EntityDefinition)/finishingEntity(org.hibernate.persister.walking.spi.EntityDefinition) ()} will be the outer set of calls. When starting with a collection, startingCollection(org.hibernate.persister.walking.spi.CollectionDefinition)/finishingCollection(org.hibernate.persister.walking.spi.CollectionDefinition) will be the outer set of calls.

- Method Detail
  - start
```
void start()
```
    Notification we are preparing to start visitation.
  - finish
```
void finish()
```
    Notification we are finished visitation.
  - startingEntity
```
void startingEntity(EntityDefinition entityDefinition)
```
    Notification we are starting to walk an entity.
    
    Parameters:
    
    entityDefinition - The entity we are preparing to walk
  - finishingEntity
```
void finishingEntity(EntityDefinition entityDefinition)
```
    Notification we are finishing walking an entity.
    
    Parameters:
    
    entityDefinition - The entity we are finishing walking.
  - startingEntityIdentifier
```
void startingEntityIdentifier(EntityIdentifierDefinition entityIdentifierDefinition)
```
    Notification we are starting to walk the identifier of an entity.
    
    Parameters:
    
    entityIdentifierDefinition - The identifier we are preparing to walk
  - finishingEntityIdentifier
```
void finishingEntityIdentifier(EntityIdentifierDefinition entityIdentifierDefinition)
```
    Notification we are finishing walking an entity.
    
    Parameters:
    
    entityIdentifierDefinition - The identifier we are finishing walking.
  - startingCollection
```
void startingCollection(CollectionDefinition collectionDefinition)
```
    Notification that we are starting to walk a collection
    
    Parameters:
    
    collectionDefinition - The collection we are preparing to walk
  - finishingCollection
```
void finishingCollection(CollectionDefinition collectionDefinition)
```
    Notification that we are finishing walking a collection
    
    Parameters:
    
    collectionDefinition - The collection we are finishing
  - startingCollectionIndex
```
void startingCollectionIndex(CollectionIndexDefinition collectionIndexDefinition)
```
    Notification that we are starting to walk the index of a collection (List/Map). In the case of a Map, if the indices (the keys) are entities this will be followed up by a call to startingEntity(org.hibernate.persister.walking.spi.EntityDefinition)
    
    Parameters:
    
    collectionIndexDefinition - The collection index we are preparing to walk.
  - finishingCollectionIndex
```
void finishingCollectionIndex(CollectionIndexDefinition collectionIndexDefinition)
```
    Notification that we are finishing walking the index of a collection (List/Map).
    
    Parameters:
    
    collectionIndexDefinition - The collection index we are finishing
  - startingCollectionElements
```
void startingCollectionElements(CollectionElementDefinition elementDefinition)
```
    Notification that we are starting to look at the element definition for the collection. If the collection elements are entities this will be followed up by a call to startingEntity(org.hibernate.persister.walking.spi.EntityDefinition)
    
    Parameters:
    
    elementDefinition - The collection element we are preparing to walk..
  - finishingCollectionElements
```
void finishingCollectionElements(CollectionElementDefinition elementDefinition)
```
    Notification that we are finishing walking the elements of a collection (List/Map).
    
    Parameters:
    
    elementDefinition - The collection element we are finishing
  - startingComposite
```
void startingComposite(CompositionDefinition compositionDefinition)
```
    Notification that we are preparing to walk a composite. This is called only for:
    - top-level composites for entity attributes. composite entity identifiers do not route through here, see startingEntityIdentifier(org.hibernate.persister.walking.spi.EntityIdentifierDefinition) if you need to hook into walking the top-level cid composite.
    - All forms of nested composite paths
    Parameters:
    
    compositionDefinition - The composite we are preparing to walk.
  - finishingComposite
```
void finishingComposite(CompositionDefinition compositionDefinition)
```
    Notification that we are done walking a composite. Called on the back-end of the situations listed on startingComposite(org.hibernate.persister.walking.spi.CompositionDefinition)
    
    Parameters:
    
    compositionDefinition - The composite we are finishing
  - startingAttribute
```
boolean startingAttribute(AttributeDefinition attributeDefinition)
```
    Notification that we are preparing to walk an attribute. May be followed by calls to startingEntity(org.hibernate.persister.walking.spi.EntityDefinition) (one-to-one, many-to-one), startingComposite(org.hibernate.persister.walking.spi.CompositionDefinition), or startingCollection(org.hibernate.persister.walking.spi.CollectionDefinition).
    
    Parameters:
    
    attributeDefinition - The attribute we are preparing to walk.
    
    Returns:
    
    true if the walking should continue; false if walking should stop.
  - finishingAttribute
```
void finishingAttribute(AttributeDefinition attributeDefinition)
```
    Notification that we are finishing walking an attribute.
    
    Parameters:
    
    attributeDefinition - The attribute we are done walking
  - foundAny
```
void foundAny(AnyMappingDefinition anyDefinition)
```
  - associationKeyRegistered
```
void associationKeyRegistered(AssociationKey associationKey)
```
  - registeredFetchSource
```
FetchSource registeredFetchSource(AssociationKey associationKey)
```
  - foundCircularAssociation
```
void foundCircularAssociation(AssociationAttributeDefinition attributeDefinition)
```
  - isDuplicateAssociationKey
