Description

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:

1. -----------------------------------------------------------------------
2. $table.Name
3. -----------------------------------------------------------------------
   $generator.parse("$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.
