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.
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.
Notification	Representation for notifications found when executing a query.
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.
RelationshipType	A relationship type is mandatory on all relationships and is used to navigate the graph.
Result	Represents the result of executing a query.
Result.ResultRow	Describes a row of a result.
Result.ResultVisitor<VisitationException extends Exception>	This is the visitor interface you need to implement to use the Result.accept(ResultVisitor) method.
Transaction	A programmatically handled transaction.

Class Summary

Class	Description
DependencyResolver.Adapter	Adapter for DependencyResolver which will select the first available candidate by default for DependencyResolver.Adapter.resolveDependency(Class).
DynamicLabel	Deprecated use Label.label(String) instead
DynamicRelationshipType	Deprecated use RelationshipType.withName(String) instead
InputPosition	An input position refers to a specific point in a query string.
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.
SeverityLevel	SeverityLevel indicates to a client the severity of a notification.

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().
TransientDatabaseFailureException	Indicates that the database is in, or meanwhile a unit of work was executing, got into an intermediate state where the unit of work, and potentially other units of work as well, couldn't complete successfully.
TransientFailureException	Indicates a type of failure that is intermediate and, in a way benign.
TransientTransactionFailureException	Indicates that a transaction couldn't complete successfully due to an intermediate failure.
