Method Detail

save

<S extends T> io.reactivex.Single<S> save(S entity)

Saves a given entity. Use the returned instance for further operations as the save operation might have changed the entity instance completely.

Parameters:

entity - must not be null.

Returns:

the saved entity.

saveAll

<S extends T> io.reactivex.Flowable<S> saveAll(Iterable<S> entities)

Saves all given entities.

Parameters:

entities - must not be null.

Returns:

the saved entities.

Throws:

IllegalArgumentException - in case the given entity is null.

saveAll

<S extends T> io.reactivex.Flowable<S> saveAll(io.reactivex.Flowable<S> entityStream)

Saves all given entities.

Parameters:

entityStream - must not be null.

Returns:

the saved entities.

Throws:

IllegalArgumentException - in case the given Publisher is null.

findById

io.reactivex.Maybe<T> findById(ID id)

Retrieves an entity by its id.

Parameters:

id - must not be null.

Returns:

the entity with the given id or Maybe.empty() if none found.

Throws:

IllegalArgumentException - if id is null.

findById

io.reactivex.Maybe<T> findById(io.reactivex.Single<ID> id)

Retrieves an entity by its id supplied by a Single.

Parameters:

id - must not be null.

Returns:

the entity with the given id or Maybe.empty() if none found.

Throws:

IllegalArgumentException - if id is null.

existsById

io.reactivex.Single<Boolean> existsById(ID id)

Returns whether an entity with the given id exists.

Parameters:

id - must not be null.

Returns:

true if an entity with the given id exists, false otherwise.

Throws:

IllegalArgumentException - if id is null.

existsById

io.reactivex.Single<Boolean> existsById(io.reactivex.Single<ID> id)

Returns whether an entity with the given id, supplied by a Single, exists.

Parameters:

id - must not be null.

Returns:

true if an entity with the given id exists, false otherwise.

Throws:

IllegalArgumentException - if id is null

findAll

io.reactivex.Flowable<T> findAll()

Returns all instances of the type.

Returns:

all entities.

findAllById

io.reactivex.Flowable<T> findAllById(Iterable<ID> ids)

Returns all instances of the type with the given IDs.

Parameters:

ids - must not be null.

Returns:

the found entities.

findAllById

io.reactivex.Flowable<T> findAllById(io.reactivex.Flowable<ID> idStream)

Returns all instances of the type with the given IDs.

Parameters:

idStream - must not be null.

the found entities.

count

io.reactivex.Single<Long> count()

Returns the number of entities available.

Returns:

the number of entities.

deleteById
