org.neo4j.kernel.impl.nioneo.store.PropertyRecord
PropertyRecord is a container for PropertyBlocks. PropertyRecords form a double linked list and each one holds one or more PropertyBlocks that are the actual property key/value pairs. Because PropertyBlocks are of variable length, a full PropertyRecord can be holding just one PropertyBlock.
