Class getContext

java.lang.Object
  jason.asSemantics.DefaultInternalAction
      jildt.getContext

All Implemented Interfaces:

jason.asSemantics.InternalAction, java.io.Serializable

public class getContext
extends jason.asSemantics.DefaultInternalAction

Internal action to get the current context of a plan. When a plan has an empty context, a "true" atom is returned.

Use:
jildt.getCurrentCtxt(P,C)

Parameters:

• + plan label (Atom): the label of the plan which will be returned the context.
  
• +/- context (Atom): the context of the plan. true if the context is empty.
  

Examples: Given the next plan: @put_label +!put(X,Y) : clear(X) & clear(Y) <- move(X,Y).

• jildt.getCurrentCtxt(put_label,C): C unifies with the atom (clear(X) & clear(Y)).
• jildt.getCurrentCtxt(put_label,true): Returns false.
• jildt.getCurrentCtxt(put_label,(clear(X) & clear(Y))): Returns true.
• jildt.getCurrentCtxt(put_label, C, B): Throws an exception due to only two arguments are needed for executing the internal action.
• jildt.getCurrentCtxt(put_label(X,Y), C): Throws an exception because the first argument must be an atom.
• jildt.getCurrentCtxt(put, 5): Throws an exception because the second argument must be either an atom or an unbounded variable.
