All Superinterfaces:

RecordAccess

All Known Implementing Classes:

public interface DiffRecordAccess
extends RecordAccess

A RecordAccess for use with incremental checking. Provides access to

Node, Relationship, and Property are the only record types one might need a previous version of when checking another type of record.

Getting the new version of a record is an operation that can always be performed without any I/O, therefore these return the records immediately, instead of returning RecordReference objects. New versions of records can be retrieved for changedNode(long) Node}, changedRelationship(long) (long) Relationship}, changedProperty(long) (long) Property}, String property blocks, and Array property blocks, these are the only types of records for which there is a need to get the new version while checking another type of record. The methods returning new versions of records return null if the record has not been changed.
