List of assertSupport() Examples

Examples of assertSupport()

org.apache.openjpa.jdbc.sql.DBDictionary.assertSupport()
Assert that the given dictionary flag is true. If it is not true, throw an error saying that the given setting needs to return true for the current operation to work.

Examples of org.apache.openjpa.jdbc.sql.DBDictionary.assertSupport()

        // exception, then just return without locking
        DBDictionary dict = _store.getDBDictionary();
        JDBCFetchConfiguration fetch = _store.getFetchConfiguration();
        if (dict.simulateLocking)
            return;
        dict.assertSupport(dict.supportsSelectForUpdate, "SupportsSelectForUpdate");


        Object id = sm.getObjectId();
        ClassMapping mapping = (ClassMapping) sm.getMetaData();


        List<SQLBuffer> sqls = getLockRows(dict, id, mapping, fetch, _store.getSQLFactory());
