Method Detail

main

public static void main(java.lang.String[] argv)

Standalone main program. One plan in, one plan out. To specify the initial plan, use the plan command-line argument. The result will be written to the file specified by the output argument. If no output is specified, the user is asked by a dialog.

addHandlers

protected void addHandlers()

Install any built-in issue and activity handlers.

Overrides:

addHandlers in class PlannerBase

plan

public void plan()

Description copied from interface: Planner

Finds a plan that is a completion of this planner's current plan and makes it the new current plan. The precise meaning of "completion" depends on the planner in question, but typically it will mean that all activities in the initial plan that might be expanded into subactions, using refinements in this planner's domain, will be expanded, and that all constraints in the initial plan or introduced by expansion would be satisfied if the plan were executed in a way that respected all of the ordering constraints. (Here, the initial plan is the plan that was current when plan() was called.)

A successful call to plan() leaves this planner in a state in which Planner.replan() can be called.

Specified by:

plan in interface Planner

Overrides:

plan in class PlannerBase

findExecutable

allActivities
