Class	Description
BlankNodeId	Functions related to blank nodes, and the implementation.
Capabilities	Interface for expressing capabilities.
FrontsNode	HasNode - interface for objects that front a Node in some context.
FrontsTriple	FrontsTriple (see also FrontsNode) is an interface for things that can be seen as wrappers round triples.
Graph	The interface to be satisfied by implementations maintaining collections of RDF triples.
GraphEventManager	The component of a graph responsible for managing events and listeners.
GraphEvents	GraphEvents is the base class for Jena general graph events.
GraphListener	Interface for listening to graph-level update events.
GraphListenerBase	A GraphListener that converts "add" and "delete" operations to GraphListenerBase.addEvent(org.apache.jena.graph.Triple) and GraphListenerBase.deleteEvent(org.apache.jena.graph.Triple) together with optional GraphListenerBase.startRead() and GraphListenerBase.finishRead().
GraphMemFactory	A factory class for creating memory Graphs.
GraphUtil	An ad-hoc collection of useful code for graphs
JenaNodeException
Node	A Node has subtypes: Node_Blank, Node_URI, Node_Literal, Node_Triple for RDF terms.
Node_ANY	A Node_ANY (there should be only one) is a meta-node that is used to stand for any other node in a query.
Node_Blank	RDF blank nodes.
Node_Ext<X>	Extension to the RDF Data model.
Node_Graph	RDF Graphs as RDF terms.
Node_Literal	An RDF node holding a literal value.
Node_Marker	Marker special nodes for datastructures.
Node_Triple	RDF triples as RDF terms for RDF-star quoted triples.
Node_URI	RDF nodes with a global identity given by a URI.
Node_Variable	"variable" nodes; these are outside the RDF specification
Node.NotLiteral	Exception thrown if a literal-access operation is attempted on a non-literal node.
NodeFactory
NodeVisitor	The NodeVisitor interface is used by Node::visitWith so that an application can have type-dispatch on the class of a Node.
TextDirection
TransactionHandler	Preliminary interface for graphs supporting transactions.
Triple	Triples are the basis for RDF statements; they have a subject, predicate, and object field (all nodes) and express the notion that the relationship named by the predicate holds between the subject and the object.
Triple.Field	A Field is a selector from Triples; it allows selectors to be passed around as if they were functions.
TripleIterator	An extended iterator that can return its next element as a Triple.
