`static int`	`FLUSH_TRUE`	Constant denoting that queries should flush data to the database automatically whenever OpenJPA determines that relevant modifications have been made and IgnoreCache is `false`.
`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.
