Trellis Application Programming Interfaces

This package provides the core resource abstractions used to describe Trellis resources.

Interface Summary

Interface	Description
AuditService	A service for producing audit-related Quad values for creation, deletion and modification operation.
Binary	The non-RDF content of an LDP NonRDFSource.
BinaryService	The BinaryService provides methods for retrieving, modifying and checking the validity of binary content.
CacheService<K,V>	A generalized caching service for Trellis.
ConstraintService	The ConstraintService defines rules that constrain RDF triples on a graph for a particular resource type.
Event	This represents the data for a server event.
EventSerializationService	A service interface for serializing an Event object into a String suitable for an external notification processor.
EventService	The EventService provides a mechanism by which events can be emitted to a message broker.
IdentifierService	The IdentifierService provides a mechanism for creating new identifiers.
IOService	The IOService defines methods for reading, writing and updating RDF streams to/from a concrete RDF 1.1 syntax.
MementoService	An interface for a Memento subsystem.
NamespaceService	Namespaces may be stored globally across the server, and the NamespaceService provides a mechanism for retrieving and setting namespace values.
RDFaWriterService	A service for generating HTML output from a stream of triples.
Resource	The central resource abstraction for a Trellis-based linked data server.
ResourceService	The ResourceService provides methods for creating, retrieving and manipulating Trellis resources.
RetrievalService<T>	A service that can retrieve resources of some type, featuring optional retrieval by time.
Session	This interface represents a user's session when interacting with a Trellis resource.

Class Summary

Class	Description
BinaryMetadata	The LDP specification divides resources into two categories: RDF resources and non-RDF resources.
BinaryMetadata.Builder	A mutable buillder for a BinaryMetadata.
ConstraintViolation	A class that represents a constraint violation in an RDF graph.
DefaultIdentifierService	The IdentifierService provides a mechanism for creating new identifiers.
Metadata	Metadata values used for resource composition.
Metadata.Builder	A mutable builder for a Metadata object.
NoopAuditService	For use when audit functionality is not desired.
NoopCacheService<K,V>	A no-op (pass-through) cache service for Trellis.
NoopEventSerializationService	For use when event serialization is not desired.
NoopEventService	For use when an event service is not desired.
NoopMementoService	A no-op MementoService implementation.
NoopNamespaceService	A NamespaceService that stores nothing and offers nothing.
NoopResourceService	A no-op resource service that can be used with CDI and proxy objects.
RDFFactory	A factory method for loading and providing the RDF Commons implementation object.
Syntax	Additional RDF Syntax definitions.
TrellisUtils	The TrellisUtils class provides a set of convenience methods related to generating and processing RDF objects.
