(Default) Flushing to occur at query execution.

Usage

From source file:org.grails.datastore.mapping.query.Query.java

/**
 * Default behavior is the flush the session before a query in the case of FlushModeType.AUTO.
 * Subclasses can override this method to disable that.
 *///from  ww  w  .j  a v a 2 s.c o m
protected void flushBeforeQuery() {
    // flush before query execution in FlushModeType.AUTO
    if (session.getFlushMode() == FlushModeType.AUTO) {
        session.flush();
    }
}
