Description

Interface Summary

DependencyResolver	Find a dependency given a type.
DependencyResolver.SelectionStrategy<T>	Responsible for making the choice between available candidates.
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.
Label	A label is a grouping facility for Node where all nodes having a label are part of the same group.
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.
ResourceIterable<T>
ResourceIterator<T>
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

DependencyResolver.Adapter	Adapter for DependencyResolver which will select the first available candidate by default for DependencyResolver.Adapter.resolveDependency(Class).
DynamicLabel	A dynamically instantiated and named Label.
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

ConstraintViolationException	Thrown when the database is asked to modify data in a way that violates one or more constraints that it is expected to uphold.
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.
