Field Detail

NEVER

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
