    public interface QueryFlushModes

Constants for determining when to flush before queries.

Since:
  0.4.0

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_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.
