All Implemented Interfaces:

Neo4jQueryRepository, Neo4jRepository<S,Long>

public class NamespaceAwareReflectiveNeo4JNodeRepositoryImpl<S>
extends ReflectiveNeo4JNodeRepositoryImpl<S>

Repository that also considers namespaces while handling Neo4J. The functionality is identical to the ReflectiveNeo4JNodeRepository, most of the search methods are EXACT meaning that a node has to have all labels EXCEPT:

findById -> also works up the hierarchy and not just for the exact match of Labels. findBy -> auto-qualifies fields. Ex. Namespace "example" field "field" the full qualifier would be "example_field". If you use ".findBy("field"...) it will automatically replace it with "example_field", but if you use "xxx_field" it WONT be changed.

Method Detail

findBy

public S findBy(String field,
                String value)

Description copied from class: AbstractNeo4JRepository

Find node by a field with a given value

Overrides:

findBy in class AbstractNeo4JRepository<S,Long>

Parameters:

field - name of field that should match

value - value that should be matched to

Returns:

first node that has the given value in the field

findAllBy

public Iterable<S> findAllBy(String field,
                             String value)

Description copied from class: AbstractNeo4JRepository

Find all science.neo4j.nodes by a field with a given value (eg. n.amount = 3)

Overrides:

findAllBy in class AbstractNeo4JRepository<S,Long>

Parameters:

field - name of field that should match

value - value that should be matched to

Returns:

all science.neo4j.nodes that have the given value in the field

findBy

public S findBy(List<Pair<String,Object>> values)

Description copied from class: AbstractNeo4JRepository

Find node by a list of fields that should match a given value

Overrides:

findBy in class AbstractNeo4JRepository<S,Long>

Parameters:

values - Key Value pairs where the key is the fieldname and the value is the value the field should match

Returns:

first node that matches on all fields

findAllBy

public Iterable<S> findAllBy(List<Pair<String,Object>> values)

Description copied from class: AbstractNeo4JRepository

Find science.neo4j.nodes by a list of fields that should match a given value

Overrides:

findAllBy in class AbstractNeo4JRepository<S,Long>

Parameters:

values - Key Value pairs where the key is the fieldname and the value is the value the field should match

Returns:

all science.neo4j.nodes that match fields

findSubtree

public S findSubtree(Long id,
                     int depth,
                     List<String> relationships)

Description copied from interface: Neo4jRepository

Returns the entire subtree of the node with the given id, or null if no such node exists

Specified by:

findSubtree in interface Neo4jRepository<S,Long>

Overrides:

findSubtree in class AbstractNeo4JNodeRepositoyImpl<S>

Parameters:

id - id of node

depth - depth until the subtree will be loaded (-1 is infinite, 0 is node only)

relationships - that will be loaded (all non mentioned will be omitted)

Returns:

node with children up to depth or null

qualifyLabel

protected String qualifyLabel(String label)

setRelationshipOverrides

public void setRelationshipOverrides(Map<String,Class> overrides)

Overrides:

setRelationshipOverrides in class ReflectiveNeo4JNodeRepositoryImpl<S>
