Method Detail

getTypesIndex

public org.neo4j.graphdb.index.Index<S> getTypesIndex()

writeTypeTo

public void writeTypeTo(S state,
                        StoredEntityType type)

Description copied from interface: TypeRepresentationStrategy

Callback for setting up and/or storing type information after creation.

Specified by:

writeTypeTo in interface TypeRepresentationStrategy<S extends org.neo4j.graphdb.PropertyContainer>

Parameters:

state - Backing state of entity being created

type - Type of entity being created
