Interface Summary

Interface	Description
DependencyResolver	Find a dependency given a type.
DependencyResolver.SelectionStrategy	Responsible for making the choice between available candidates.
ExecutionPlanDescription	Instances describe single execution steps in a Cypher query execution plan Execution plans form a tree of execution steps.
ExecutionPlanDescription.ProfilerStatistics	Instances describe statistics from the profiler of a particular step in the execution plan.
Expander	Deprecated Deprecated because RelationshipExpander is deprecated.
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.
QueryStatistics	Represents statistics about the effects of a query.
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 graph.
Resource	Resource that should be closed when not needed anymore.
ResourceIterable<T>	Iterable whose iterators have associated resources that need to be released.
ResourceIterator<T>	Closeable Iterator with associated resources.
Result	Represents the result of executing a query.
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

Class	Description
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.
PathExpanderBuilder	A fluent builder for creating specialized path expanders.
PathExpanders	A catalog of convenient PathExpander factory methods.
QueryExecutionType	Signifies how a query is executed, as well as what side effects and results could be expected from the query.

Enum Summary

Enum	Description
Direction	Defines relationship directions used when getting relationships from a node or when creating traversers.
QueryExecutionType.QueryType	Signifies what type of query an QueryExecutionType executes.
Traverser.Order	Defines a traversal order as used by the traversal framework.

Exception Summary

Exception	Description
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.
DatabaseShutdownException
InvalidTransactionTypeException
MultipleFoundException	This exception will be thrown when one or less entities were expected, yet multiple were found.
NotFoundException	This exception will be thrown if a request is made to a node, relationship or property that does not exist.
NotInTransactionException	Thrown when attempting to access or modify the graph outside of a transaction.
QueryExecutionException	This exception is thrown from the execute method when there is an error during the execution of a query.
TransactionFailureException	Signals that a transaction failed and has been rolled back.
TransactionTerminatedException	Signals that the transaction within which the failed operations ran has been terminated with Transaction.terminate().
