Description copied from interface: ISystemTransformer

Destructively update the syntax tree ast. Also modify the in-memory represention of the Bogor-configuration file (configuration), to remove old config data useful for the system before this transformation, and insert new configuration directives appropriate to the post-state.

Specified by:

transformSystem in interface ISystemTransformer

Parameters:

ast - the incoming syntax tree. This should be modified in-place.
