public interface Directive
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:
Jomi Fred Hubner, Rafael H. Bordini, and Michael Wooldridge.
Programming declarative goals using plan patterns.

Method Details
-
begin
called when the directive is declared -
process
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.
-
end
called when the directive ends -
isSingleton
boolean isSingleton()returns true if the same instance will be used by all agents/parsers in the JVM
