Class Neo4jTemplate

All Implemented Interfaces:

@Deprecated
public class Neo4jTemplate
extends Object
implements Neo4jOperations, InitializingBean

Spring Data template for Neo4j, which is an implementation of Neo4jOperations. Indeed, framework users are encouraged to favour coding against the Neo4jOperations interface rather than the Neo4jTemplate directly, as the interface API will be more consistent over time and enhanced proxy objects of the interface may actually be created by Spring for auto-wiring instead of this template. Please note also that all methods on this class throw a DataAccessException if any underlying Exception is thrown. Since DataAccessException is a runtime exception, this is not documented at the method level.

Neo4jTemplate

public Neo4jTemplate()

Deprecated.

Create a new Neo4jTemplate instance.

Neo4jTemplate

@Autowired
public Neo4jTemplate(org.neo4j.ogm.session.SessionFactory sessionFactory)

Deprecated.

Constructs a new Neo4jTemplate based on the given Neo4j OGM SessionFactory.

Parameters:

sessionFactory - The Neo4j OGM SessionFactory upon which to base the template

Method Detail

setSessionFactory

public void setSessionFactory(org.neo4j.ogm.session.SessionFactory sessionFactory)

Deprecated.

getSessionFactory

public org.neo4j.ogm.session.SessionFactory getSessionFactory()

Deprecated.

afterPropertiesSet

public void afterPropertiesSet()

Deprecated.

Specified by:

afterPropertiesSet in interface InitializingBean

execute

public <T> T execute(Neo4jCallback<T> action)
              throws DataAccessException

Deprecated.

Description copied from interface: Neo4jOperations

Execute the action specified by the given action object within a Session.

Application exceptions thrown by the action object get propagated to the caller (can only be unchecked). OGM exceptions are transformed into appropriate DAO ones. Allows for returning a result object, that is a domain object or a collection of domain objects.

Note: Callback code is not supposed to handle transactions itself! Use an appropriate transaction manager like Neo4jTransactionManager. Generally, callback code must not touch any Session lifecycle methods, like close, disconnect, or reconnect, to let the template do its work.

Specified by:

execute in interface Neo4jOperations

Parameters:

action - callback object that specifies the OGM action

Returns:

a result object returned by the action, or null

Throws:

DataAccessException

Each of the resultant maps corresponds to a "row" in the result set and the key set in each map contains all the names contained in the RETURN clause of the given query.

Specified by:

query in interface Neo4jOperations

Parameters:

cypher - The Cypher query to execute

parameters - The parameter to merge into the cypher query or an empty Map if the given query isn't parameterised

Returns:

A Query containing an Iterable map representing query results and QueryStatistics if applicable.

queryForObjects

public <T> Iterable<T> queryForObjects(Class<T> objectType,
                                       String cypher,
                                       Map<String,?> parameters)

Deprecated.

Description copied from interface: Neo4jOperations

Runs the specified Cypher query with the given parameters against the underlying Neo4j database and returns the result marshalled as a group of objects of the requested type.

Specified by:

queryForObjects in interface Neo4jOperations

Parameters:

objectType - The Class denoting the type of entity to return

cypher - The Cypher query to execute

parameters - The parameter to merge into the Cypher query or an empty Map if the query's not parameterised

Returns:

An Iterable over the entities found by executing the query or an empty Iterable if nothing is found by the query, never null

query

public org.neo4j.ogm.model.Result query(String cypher,
                                        Map<String,?> parameters,
                                        boolean readOnly)

Deprecated.

Description copied from interface: Neo4jOperations

Given a cypher statement this method will return a Query object containing a collection of Map's which represent Neo4j objects as properties, along with query statistics if applicable. Each element of the query result is a map which you can access by the name of the returned field TODO: Are we going to use the neo4jOperations conversion method to cast the value object to its proper class?

Specified by:

query in interface Neo4jOperations

Parameters:

cypher - The parametrisable cypher to execute.

parameters - Any parameters to attach to the cypher.

readOnly - true if the query is readOnly, false otherwise

Returns:

A Query of Iterables with each entry representing a neo4j object's properties.

queryForObject

public <T> T queryForObject(Class<T> objectType,
                            String cypher,
                            Map<String,?> parameters)

Deprecated.

Description copied from interface: Neo4jOperations

Specified by:

queryForObject in interface Neo4jOperations

Parameters:

objectType - The Class denoting the type of entity to return

cypher - The Cypher query to execute

parameters - The parameter to merge into the Cypher query or an empty Map if the query's not parameterised

Returns:

An instance of T that corresponds to the entity found by executing the query or null if nothing is found by the query

count

public long count(Class<?> entityClass)

Deprecated.

Description copied from interface: Neo4jOperations
