Interface Summary

DependencyResolver	Find a dependency given a type.
Expander	This interface is an extension of the RelationshipExpander interface that makes it possible to build customized versions of an Expander.
GraphDatabaseService	The main access point to a running Neo4j instance.
Lock	An acquired lock on an entity for a transaction, acquired from Transaction.acquireWriteLock(PropertyContainer) or Transaction.acquireReadLock(PropertyContainer) this lock can be released manually using Lock.release().
Node	A node in the graph with properties and relationships to other entities.
Path	Represents a path in the graph.
PathExpander<STATE>	An expander of relationships.
PropertyContainer	Defines a common API for handling properties on both nodes and relationships.
Relationship	A relationship between two nodes in the graph.
RelationshipExpander	Deprecated. in favor or PathExpander.
RelationshipType	A relationship type is mandatory on all relationships and is used to navigate the node space.
ReturnableEvaluator	Deprecated. because of the introduction of a new traversal framework, see more information at TraversalDescription and Traversal and the new traversal framework's equivalent Predicate.
StopEvaluator	Deprecated. because of the introduction of a new traversal framework, see more information at TraversalDescription and Traversal and the new traversal framework's equivalent Evaluator.
Transaction	A programmatically handled transaction.
TraversalPosition	Encapsulates information about the current traversal position.
Traverser	Deprecated. because of an unnatural and too tight coupling with Node.

Class Summary

DynamicRelationshipType

A dynamically instantiated and named RelationshipType.

Enum Summary

Direction	Defines relationship directions used when getting relationships from a node or when creating traversers.
Traverser.Order	Defines a traversal order as used by the traversal framework.

Exception Summary

NotFoundException	This exception will be thrown if a request is made to a node, relationship or property that does not exist.
NotInTransactionException	An exception that is thrown whenever an API operation that requires a transaction is executed but no transaction is running.
TransactionFailureException	Signals that a transaction failed and has been rolled back.
