Method Detail

postEntityCreation

public void postEntityCreation(org.neo4j.graphdb.Node 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<org.neo4j.graphdb.Node>

Parameters:

state - Backing state of entity being created

type - Type of entity being created

findAll

public <U> org.neo4j.helpers.collection.ClosableIterable<org.neo4j.graphdb.Node> findAll(Class<U> clazz)

Specified by:

findAll in interface TypeRepresentationStrategy<org.neo4j.graphdb.Node>

Parameters:

clazz - Type whose instances should be iterated over

Returns:

lazy Iterable over all instances of the given type

count

public long count(Class<?> entityClass)

Specified by:

count in interface TypeRepresentationStrategy<org.neo4j.graphdb.Node>

Returns:

number of instances of this class contained in the graph

getJavaType

public Class<?> getJavaType(org.neo4j.graphdb.Node node)

Specified by:

getJavaType in interface TypeRepresentationStrategy<org.neo4j.graphdb.Node>

Returns:

java type that of the node entity of this node

preEntityRemoval

public void preEntityRemoval(org.neo4j.graphdb.Node state)

Description copied from interface: TypeRepresentationStrategy

Callback for cleaning up type information before removal. If state does not have any state associated, doesn't do anything.

Specified by:

preEntityRemoval in interface TypeRepresentationStrategy<org.neo4j.graphdb.Node>

Parameters:

state - Backing state of entity being removed
