public class current_intention
extends DefaultInternalAction

Internal action: .current_intention.

Description: returns a description of the current intention. It is useful for plans that need to inspect the current intention. The description of the intention has the following form:

intention(id,stack of intended means)

where each intended means has the form:

im(plan label,trigger event,plan body term, unification function (a list of maps))

For example:

intention(1,
[
im(l__6[source(self)], {+!g3}, { .current_intention(I); .print(end) }, [map(I, ....)]),
im(l__5[source(self)], {+!g5(10)}, { !g3; .fail }, []),
im(l__4[source(self)], {+!start}, { !g5(X); .print(endg4) }, [map(X, test)]),
...
])

Parameters:

  • - intention (structure): the variable that unifies with the intention description.

Example:

  • .current_intention(X): X unifies with the description of the current intention (i.e. the intention that executed this internal action).

Notes:

  • The internal action .intention(ID,State,Stack,current) can be used in place of .current_intention.
  • In case this internal action is used in the body of a plan, the intention that are executing the plan is used.
  • In case this internal action is used in the context of a plan, the intention that produced the event is used.
