Method Detail

get

public CompletionStage<? extends Resource> get(IRI identifier)

Description copied from interface: RetrievalService

Get a resource by the given identifier.

Specified by:

get in interface RetrievalService<Resource>

Parameters:

identifier - the resource identifier

Returns:

the resource

replace

public CompletionStage<Void> replace(Metadata metadata,
                                     Dataset data)

Description copied from interface: ResourceService

Replace a resource in the server.

Specified by:

replace in interface ResourceService

Parameters:

metadata - metadata for the resource

data - the dataset to be persisted

Returns:

a new completion stage that, when the stage completes normally, indicates that the supplied data were successfully stored in the corresponding persistence layer. In the case of an unsuccessful write operation, the CompletionStage will complete exceptionally and can be handled with CompletionStage.handle(java.util.function.BiFunction<? super T, java.lang.Throwable, ? extends U>), CompletionStage.exceptionally(java.util.function.Function<java.lang.Throwable, ? extends T>) or similar methods.

delete

public CompletionStage<Void> delete(Metadata metadata)

Description copied from interface: ResourceService

Delete a resource from the server.

Specified by:

delete in interface ResourceService

Parameters:

metadata - metadata for the resource

Returns:

a new completion stage that, when the stage completes normally, indicates that the resource was successfully deleted from the corresponding persistence layer. In the case of an unsuccessful delete operation, the CompletionStage will complete exceptionally and can be handled with CompletionStage.handle(java.util.function.BiFunction<? super T, java.lang.Throwable, ? extends U>), CompletionStage.exceptionally(java.util.function.Function<java.lang.Throwable, ? extends T>) or similar methods.

add

public CompletionStage<Void> add(IRI identifier,
                                 Dataset newData)

Specified by:

add in interface ResourceService

Parameters:

identifier - the identifier under which to persist a dataset

newData - a dataset to persist

Returns:

a new completion stage that, when the stage completes normally, indicates that the supplied data were successfully stored in the corresponding persistence layer. In the case of an unsuccessful write operation, the CompletionStage will complete exceptionally and can be handled with CompletionStage.handle(java.util.function.BiFunction<? super T, java.lang.Throwable, ? extends U>), CompletionStage.exceptionally(java.util.function.Function<java.lang.Throwable, ? extends T>) or similar methods.

touch

public CompletionStage<Void> touch(IRI identifier)

Description copied from interface: ResourceService

Update the modification date of the provided resource.

Specified by:

touch in interface ResourceService

Parameters:

identifier - the identifier of the resource

Returns:

a new completion stage that, when the stage completes normally, indicates that the identified resource has been updated with a new modification date.

supportedInteractionModels

public Set<IRI> supportedInteractionModels()

Description copied from interface: ResourceService

Return a collection of interaction models supported by this Resource Service.

Specified by:

supportedInteractionModels in interface ResourceService

Returns:

a set of supported interaction models

generateIdentifier

public String generateIdentifier()

Description copied from interface: ResourceService

An identifier generator.

Specified by:

generateIdentifier in interface ResourceService

Returns:

a new identifier
