void flush()
```
    Flushes all pending changes to the database.
  - saveAndFlush
```
<S extends T> S saveAndFlush(S entity)
```
    Saves an entity and flushes changes instantly.
    
    Parameters:
    
    entity - entity to be saved. Must not be null.
    
    Returns:
    
    the saved entity
  - saveAllAndFlush
```
<S extends T> List<S> saveAllAndFlush(Iterable<S> entities)

  - deleteInBatch
```
@Deprecated
default void deleteInBatch(Iterable<T> entities)
```
    Deprecated. Use deleteAllInBatch(Iterable) instead.
    
    Deletes the given entities in a batch which means it will create a single query. This kind of operation leaves JPAs first level cache and the database out of sync. Consider flushing the EntityManager before calling this method.
    
    Parameters:
    
    entities - entities to be deleted. Must not be null.
  - deleteAllInBatch
```
void deleteAllInBatch(Iterable<T> entities)
```
    Deletes the given entities in a batch which means it will create a single query. This kind of operation leaves JPAs first level cache and the database out of sync. Consider flushing the EntityManager before calling this method.
    
    Parameters:
    
    entities - entities to be deleted. Must not be null.
    
    Since:
    
    2.5
  - deleteAllByIdInBatch
```
void deleteAllByIdInBatch(Iterable<ID> ids)
```
    Deletes the entities identified by the given ids using a single query. This kind of operation leaves JPAs first level cache and the database out of sync. Consider flushing the EntityManager before calling this method.
    
    Parameters:
    
    ids - the ids of the entities to be deleted. Must not be null.
    
    Since:
    
    2.5
  - deleteAllInBatch
```
void deleteAllInBatch()
```
    Deletes all entities in a batch call.
  - getOne
```
@Deprecated
T getOne(ID id)
```
    Deprecated. use JpaRepository#getReferenceById(ID) instead.
    
    Returns a reference to the entity with the given identifier. Depending on how the JPA persistence provider is implemented this is very likely to always return an instance and throw an EntityNotFoundException on first access. Some of them will reject invalid identifiers immediately.
    
    Parameters:
    
    id - must not be null.
    
    Returns:
    
    a reference to the entity with the given identifier.
    
    See Also:
    
    for details on when an exception is thrown.
  - getById
```
@Deprecated
T getById(ID id)
```
    Deprecated. use JpaRepository#getReferenceById(ID) instead.
    
    Returns a reference to the entity with the given identifier. Depending on how the JPA persistence provider is implemented this is very likely to always return an instance and throw an EntityNotFoundException on first access. Some of them will reject invalid identifiers immediately.
    
    Parameters:
    
    id - must not be null.
    
    Returns:
    
    a reference to the entity with the given identifier.
    
    Since:
    
    2.5
    
    See Also:
    
    for details on when an exception is thrown.
  - getReferenceById
```
T getReferenceById(ID id)
```
    Returns a reference to the entity with the given identifier. Depending on how the JPA persistence provider is implemented this is very likely to always return an instance and throw an EntityNotFoundException on first access. Some of them will reject invalid identifiers immediately.
    
    Parameters:
    
    id - must not be null.
    
    Returns:
    
    a reference to the entity with the given identifier.
    
    Since:
    
    2.7
