public interface Directive

Interface for all compiler directives (e.g. include and goal patterns).

There are two kinds of directives: single directive and begin/end directive. The single directive does not have inner plans, as, for instance, the include:
...
{ include("a.asl") }
...

begin/end directives have inner plans, as used in goal patterns:
...
{ begin ebdg(g) }
+!g : bel <- action1.
+!g <- action2.
{ end }
...

This pattern will change these two plans to:
+!g : g.
+!g : not (p__1(g)) & bel <- +p__1(g); action1; ?g.
+!g : not (p__2(g)) <- +p__2(g); action2; ?g.
-!g <- !g.
+g <- -p__1(g); -p__2(g); .dropGoal(g,true).

Goal patterns are proposed in the paper:

Method Detail

process

Agent process(Pred directive,
              Agent outerContent,
              Agent innerContent)
This method is called to process the directive.

Parameters:
directive - the directive as defined in the source (e.g. "include("bla.asl")")
outerContent - the representation of the agent where the directive is being processed (the method should not change this agent state)
innerContent - the content (plans, beliefs, ...) inside the begin/end directive (as in goal patterns)
Returns:
the agent (plans, bels, ...) with the result of the directive.
