Method Detail

getTypesIndex

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

postEntityCreation

public void postEntityCreation(S state,
                               Class<?> type)

Description copied from interface: TypeRepresentationStrategy

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

Specified by:

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

Parameters:

state - Backing state of entity being created

type - Type of entity being created

count

public long count(Class<?> entityClass)

Specified by:

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

Returns:

number of instances of this class contained in the graph

Specified by:

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

Parameters:

clazz - Type whose instances should be iterated over

Returns:

lazy Iterable over all instances of the given type

getJavaType

public <U> Class<U> getJavaType(S propertyContainer)

Specified by:

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

Returns:

java type that of the node entity of this node

addToTypesIndex

protected void addToTypesIndex(S relationshipOrNode,
                               Class<?> entityClass)
