Need ability to pass global user-configurable platform-specific hints to templates
----------------------------------------------------------------------------------

         Key: TORQUE-27
         URL: http://issues.apache.org/jira/browse/TORQUE-27
     Project: Torque
        Type: Improvement

  Components: Generator  
    Versions: 3.2    
 Environment: Fedora Core 5 Linux, Sun JDK1.4.2_08.
    Reporter: Adrian Price
    Priority: Minor


It would be useful to provide a generic mechanism to enable the user to pass global platform-specific
hints to templates. For example, for MySQL it is desirable to explicitly specify the type
of table to be created, e.g., CREATE TABLE foo (...) Type = InnoDB. Such global hints could
then be specified by the user through platform specific properties or property files, as in:


platform.properties:
mysql.table.hint=Type = InnoDB. 

A matching table.vm template might look something like:

# -----------------------------------------------------------------------
# $table.Name
# -----------------------------------------------------------------------
$generator.parse("$basepath/drop.vm", "", "table", $tbl)
CREATE TABLE $table.Name
(
etc...
) $platform.getProperty('mysql.table.hint');

Without such a capability it is necessary to hard-code the required customizations into the
templates, which is a rather inflexible and inconvenient way of doing it.
