Field Summary

static int	FLUSH_FALSE Constant denoting that queries should never flush data to the database automatically before executing a query, but should instead execute queries in-memory if necessary.

static int	FLUSH_WITH_CONNECTION Constant denoting that queries should flush data to the database automatically when OpenJPA determines that relevant modifications have been made and the current context already has a dedicated connection.
