Class SystemTransformer

java.lang.Object
  ua.gradsoft.termware.AbstractBuildinTransformer
      ua.gradsoft.termware.transformers.sys.SystemTransformer

All Implemented Interfaces:

ITermTransformer

public class SystemTransformer
extends AbstractBuildinTransformer

Transformer for system definiton term. System definition term is term system(name,facts,ruleset,strategy) - which means define into current root domain system with name 'name' and facts 'facts' and ruleset 'ruleste' with strategy 'strategy'. Note, that system term can be a part of domain term - in such way systems can be hierarchically organized by domains.

transform

public Term transform(Term t,
                      TermSystem sys,
                      TransformationContext ctx)
               throws TermWareException

in t must be system definition. Transformer transform one to true and add system to current TermWare instance. If t does not contain system definition - leave it unchanged.

Parameters:

t - - term to transform

sys - - system which give us access to ebvironment.

ctx - - context of transformation.

Returns:

- transformed term.

Throws:

TermWareException

static_transform

public static Term static_transform(Term t,
                                    TermSystem sys,
                                    TransformationContext ctx)
                             throws TermWareException

Throws:

TermWareException
