Method Detail

setValue

public Object setValue(Object entity,
                       Object newVal)

Description copied from interface: FieldAccessor

handles field write modification.

Returns:

the written value or a DoReturn wrapper with the written value or null. DoReturn indicates that the aspect should not proceed to the original field access but instead return immediately.

isWriteable

public boolean isWriteable(Object entity)

Specified by:

isWriteable in interface FieldAccessor

Overrides:

isWriteable in class AbstractNodeRelationshipFieldAccessor<org.neo4j.graphdb.Node,org.neo4j.graphdb.Relationship>

Returns:

false for read only or computed fields, true otherwise

getValue

public Object getValue(Object entity)

Returns:

the value or a DoReturn wrapper with the value for the field. DoReturn indicates that the aspect should not proceed to the original field access but instead return immediately.

getStatesFromEntity

protected Iterable<org.neo4j.graphdb.Relationship> getStatesFromEntity(Object entity)

Specified by:

getStatesFromEntity in class AbstractNodeRelationshipFieldAccessor<org.neo4j.graphdb.Node,org.neo4j.graphdb.Relationship>

obtainSingleRelationship

protected org.neo4j.graphdb.Relationship obtainSingleRelationship(org.neo4j.graphdb.Node start,
                                                                  org.neo4j.graphdb.Relationship end)

Specified by:

obtainSingleRelationship in class AbstractNodeRelationshipFieldAccessor<org.neo4j.graphdb.Node,org.neo4j.graphdb.Relationship>

getState

protected org.neo4j.graphdb.Node getState(Object entity)

Specified by:

getState in class AbstractNodeRelationshipFieldAccessor<org.neo4j.graphdb.Node,org.neo4j.graphdb.Relationship>
