Examples of org.apache.derby.iapi.store.raw.RecordHandle

org.apache.derby.iapi.store.raw.RecordHandle
A handle to a record within a container. This interface does not provide an information about the data of the record, it is only used to perform updates, deletes and allow ordered record manipulation. MT - immutable @see Page
