Remarks

You must call the assert method on the same tier, usually the server tier, that the corresponding CodeAccessPermission::demand method is called on before the protected API is executed. Call a method on the server tier from one of the following:

• A server static method
• A class instance method that is set to run on the server by using the RunOn class property.

The following example deletes data from the xRefNames table. The assert method is called to declare that the code can then instantiate the AsciiIo class that is used to read and write data to a file.

{ 
    DictTable dictTable = new DictTable(tablenum(xRefNames)); 
    str sqlTableName; 
    SqlDataDictionary sqlTable; 
    if (dictTable && dictTable.enabled()) 
    { 
        sqlTableName = dictTable.name(DbBackend::Sql); 
        sqlTable = new SqlDataDictionary(); 
        // Try to truncate only if the table does exist 
        // in the SQL database. 
        if (sqlTable.tableExist(sqlTableName)) 
        { 
            new SqlDataDictionaryPermission( 
                methodstr(SqlDataDictionary, tableTruncate)).assert(); 
            sqlTable.tableTruncate(tablenum(xRefNames)); 
            CodeAccessPermission::revertAssert(); 
        } 
    } 
}
