RecordAggregate

public RecordAggregate()

visitContainedRecords

public abstract void visitContainedRecords(RecordAggregate.RecordVisitor rv)

Visit each of the atomic BIFF records contained in this RecordAggregate in the order that they should be written to file. Implementors may or may not return the actual Records being used to manage POI's internal implementation. Callers should not assume either way, and therefore only attempt to modify those Records after cloning
