Field Detail

NEVER

public static final FlushMode NEVER

Deprecated. use MANUAL instead.

The Session is never flushed unless Session.flush() is explicitly called by the application. This mode is very efficient for read only transactions.

MANUAL

The Session is only ever flushed when Session.flush() is explicitly called by the application. This mode is very efficient for read only transactions.

COMMIT

public static final FlushMode COMMIT

The Session is flushed when Transaction.commit() is called.

AUTO

public static final FlushMode AUTO

The Session is sometimes flushed before query execution in order to ensure that queries never return stale state. This is the default flush mode.

ALWAYS

public static final FlushMode ALWAYS

The Session is flushed before every query. This is almost always unnecessary and inefficient.
