public MongoNodeService()

Method Details

save

public void save(NodeWrapperDto nodeWrapper)

Persists the given wrapped node metadata.

This implementation simply delegates to CrudRepository.save(Object) after mapping the DTO to the persistence entity.

Specified by:

save in interface NodeService

Parameters:

nodeWrapper - the node wrapper to store

findById

public NodeWrapperDto findById(String nodeId)

Retrieves the stored node wrapper by its identifier.

Specified by:

findById in interface NodeService

Parameters:

nodeId - the Alfresco node identifier

Returns:

the stored NodeWrapperDto

Throws:

NodeNotFoundOnVaultException - if the node does not exist

findByArchiveDateRange

public org.springframework.data.domain.Page<NodeWrapperDto> findByArchiveDateRange(Instant from,
 Instant to,
 org.springframework.data.domain.Pageable pageable)

Retrieves node wrappers archived within the specified date range using pagination. Both bounds are inclusive. Passing null for one of the parameters will make the range open-ended on that side.

Specified by:

findByArchiveDateRange in interface NodeService

Parameters:

from - the lower bound of the archive date range, inclusive

to - the upper bound of the archive date range, inclusive

pageable - pagination information

Returns:

page of NodeWrapperDto

findNotarized

public org.springframework.data.domain.Page<NodeWrapperDto> findNotarized(org.springframework.data.domain.Pageable pageable)

Retrieves notarized node wrappers using pagination.

This implementation delegates to MongoNodeRepositoryImpl.findNotarized(Pageable).

Specified by:

findNotarized in interface NodeService

Parameters:

pageable - pagination information

Returns:

page of notarized NodeWrapperDto

countNotarized

public long countNotarized()

Description copied from interface: NodeService

Counts nodes that have already been notarized.

Specified by:

countNotarized in interface NodeService

Returns:

number of notarized nodes

findNotarizedRandom

public List<NodeWrapperDto> findNotarizedRandom(int size)

Description copied from interface: NodeService

Retrieves a random sample of notarized nodes.

Specified by:

findNotarizedRandom in interface NodeService

Parameters:

size - maximum number of nodes to return

Returns:

random notarized nodes

findByNtx

public Iterable<NodeWrapperDto> findByNtx(String ntx)

Retrieves all node wrappers having the given notarization transaction ID. A null transaction ID is used to select nodes that have not yet been notarized.

Specified by:

findByNtx in interface NodeService

Parameters:

ntx - the notarization transaction ID to filter by

Returns:

iterable collection of NodeWrapperDto

findByKv

public Iterable<NodeWrapperDto> findByKv(int kv)

Retrieves all node wrappers associated with the specified encryption key version.

Specified by:

findByKv in interface NodeService

Parameters:

kv - the encryption key version to filter by

Returns:

iterable collection of NodeWrapperDto

findAll

public Iterable<NodeWrapperDto> findAll()

Retrieves all stored node wrappers.

The returned iterable is backed by the underlying repository and reflects the current state of the vault.

Specified by:

findAll in interface NodeService

Returns:

iterable collection of NodeWrapperDto

deleteById

public void deleteById(String nodeId)

Deletes the node wrapper identified by the given ID.

Specified by:

deleteById in interface NodeService

Parameters:

nodeId - the Alfresco node identifier
