setAssociationConsistent

public void setAssociationConsistent(boolean consistent)

Sets the association-consistent flag for this Row Set.

Association-consistent mode allows the user to see data that includes changes not yet posted to database, but at the cost of degraded performance.

When association-consistency is on the Row Set will reflect rows with modified foreign keys, newly created rows, and removed (deleted) rows. When association-consistency is off the user must post pending changes to database to make them visible.

This method is relevant only if this Row Set was one returned from a call to an entity association accessor.
