Class BehaviorWorkExecutor

java.lang.Object

cz.cuni.amis.pogamut.sposh.executor.BehaviorWorkExecutor

All Implemented Interfaces:

ILogicWorkExecutor, IWorkExecutor

public class BehaviorWorkExecutor
extends Object
implements ILogicWorkExecutor

Executor for posh plans that will execute annotated methods on the object.

You put behavior objects into this IWorkExecutor that have some methods annotated with SPOSHAction or SPOSHSense. Names of these methods are used stored as primitives. There can't be two behavior methods with same names, (e.g. testMethod() from behavior object A and testMethod() from object B or testMethod(String) from object A). If such sitation occurs, BehaviorWorkExecutor#addBehavior(java.lang.Object) will throw IllegalArgumentException.

When PoshEngine asks to execute some primitive, this executor will look in list of primitives it is capable to execute (names of annotated methods from behavior objects) and if it has some behavior method with same name, it executed it and returns value.

Constructor Detail

BehaviorWorkExecutor

public BehaviorWorkExecutor()

Create BehaviorWorkExecutor with no methods.

BehaviorWorkExecutor

public BehaviorWorkExecutor(JavaBehaviour behavior)

Create BehaviorWorkExecutor with primitives from behavior.

Parameters:

behavior - object from which we will add primitives into this worker.

Method Detail

addBehavior

public void addBehavior(JavaBehaviour behavior)

Take the behavior object, find its methods annotated with either SPOSHAction or SPOSHSense and add them as primitives this work executor can process.

Parameters:

behavior -

Throws:

IllegalArgumentException - if behavior contains primitive method with same name, that is already contained in primitives of this worker.

executeSense

public Object executeSense(String primitive,
                  VariableContext ctx)

Uses executePrimitive(String, VariableContext).

Specified by:

executeSense in interface IWorkExecutor

Parameters:

primitive - name of primitive

ctx - variable context for sense containing possible parameters

Returns:

result of executed primitive

executeAction

public ActionResult executeAction(String primitive,
                         VariableContext ctx)

Uses executePrimitive(String, VariableContext).

Specified by:

executeAction in interface IWorkExecutor

Parameters:

primitive - name of primitive

ctx - variable context for action containing possible parameters

Returns:

result of executed primitive

logicAfterPlan

public void logicAfterPlan()

Description copied from interface: ILogicWorkExecutor

Method that is triggered every time the plan for executor is evaluated. It is triggered right after the plan evaluation.

Specified by:

logicAfterPlan in interface ILogicWorkExecutor

logicBeforePlan

public void logicBeforePlan()

Description copied from interface: ILogicWorkExecutor

Method that is triggered every time the plan for executor is evaluated. It is triggered right before the plan evaluation.

Specified by:

logicBeforePlan in interface ILogicWorkExecutor
