CRUD interface for graph repositories, used as base repository for crud operations

Method Summary

long	count() uses the configured TypeRepresentationStrategy, depending on the strategy this number might be an approximation
void	delete(Iterable<? extends T> entities) deletes the given entities by calling their entity.remove() methods
void	delete(T entity) deletes the given entity by calling its entity.remove() method
void	deleteAll() removes all entities of this type, use with care
boolean	exists(Long id)
EndResult<T>	findAll() uses the configured TypeRepresentationStrategy to load all entities, might return a large result
org.springframework.data.domain.Page<T>	findAll(org.springframework.data.domain.Pageable pageable) finder that takes the provided sorting and paging into account NOTE: the sorting is not yet implemented
EndResult<T>	findAll(org.springframework.data.domain.Sort sort) finder that takes the provided sorting into account NOTE: the sorting is not yet implemented
T	findOne(Long id)
Class	getStoredJavaType(Object entity)
EndResult<T>	query(String query, Map<String,Object> params)
<U extends T> Iterable<U>	save(Iterable<U> entities) persists the provided entities by forwarding to their entity.persist() methods

Specified by:

save in interface org.springframework.data.repository.CrudRepository<T,Long>

Parameters:

entity - to be persisted

Returns:

the saved entity (being the same reference as the parameter)

save

@Transactional
<U extends T> Iterable<U> save(Iterable<U> entities)

persists the provided entities by forwarding to their entity.persist() methods

Specified by:

save in interface org.springframework.data.repository.CrudRepository<T,Long>

true if the entity with this id exists

findAll

EndResult<T> findAll()

uses the configured TypeRepresentationStrategy to load all entities, might return a large result

Specified by:

findAll in interface org.springframework.data.repository.CrudRepository<T,Long>

Returns:

all entities of the given type NOTE: please close the iterable if it is not fully looped through

count

long count()

uses the configured TypeRepresentationStrategy, depending on the strategy this number might be an approximation

Specified by:

count in interface org.springframework.data.repository.CrudRepository<T,Long>

Returns:

number of entities of this type in the graph

delete

@Transactional
void delete(T entity)

deletes the given entity by calling its entity.remove() method
