Class NeoStore

          org.neo4j.kernel.impl.nioneo.store.NeoStore

public class NeoStore
extends AbstractStore

This class contains the references to the "NodeStore,RelationshipStore, PropertyStore and RelationshipTypeStore". NeoStore doesn't actually "store" anything but extends the AbstractStore for the "type and version" validation performed in there.

This default implementation does nothing.

Overrides:

initStorage in class CommonAbstractStore

closeStorage

protected void closeStorage()

Closes the node,relationship,property and relationship type stores.

Overrides:

closeStorage in class CommonAbstractStore

flushAll

public void flushAll()

Overrides:

flushAll in class CommonAbstractStore

getTypeDescriptor

public String getTypeDescriptor()

Description copied from class: CommonAbstractStore

Returns the type and version that identifies this store.

Specified by:

getTypeDescriptor in class CommonAbstractStore

Returns:

This store's implementation type and version identifier

getIdGeneratorFactory

public IdGeneratorFactory getIdGeneratorFactory()

getRecordSize

public int getRecordSize()

Description copied from class: AbstractStore
