Method Summary

Modifier and Type	Method	Description
RecoveryGoalContext	copy(Context newParent)	Make a copy of this node in the execution tree for simulation purposes
ParameterizedAction	getRecoveryAction()
protected void	resetConcreteContext()	This resets fields specific to concrete sub-classes and should be overridden by inheriting classes if additional resetting needs to happen.
boolean	setStatus(ActionStatus eStatus, Justification justification)	Overriding setStatus to "catch" failures when a recovery operation should take place, and also to convert un-caught failures to FAIL_RECOVERY so the parent goal context can handle recovery failures differently from regular goal/action failures.
void	setupNextStep()	If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

 ExecutionType executionType,
 Recovery recovery)

Method Details

setupNextStep

public void setupNextStep()

Description copied from class: Context

If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

Overrides:

setupNextStep in class GoalContext

resetConcreteContext

protected void resetConcreteContext()

Description copied from class: Context

This resets fields specific to concrete sub-classes and should be overridden by inheriting classes if additional resetting needs to happen.

Overrides:

resetConcreteContext in class GoalContext

setStatus

public boolean setStatus(ActionStatus eStatus,
 Justification justification)

Overriding setStatus to "catch" failures when a recovery operation should take place, and also to convert un-caught failures to FAIL_RECOVERY so the parent goal context can handle recovery failures differently from regular goal/action failures. TODO: This method is synchronized to handle canceling. Is there a better way to handle this?

Overrides:

setStatus in class GoalContext

Parameters:

eStatus - the execution status of the currently running event

justification - the reason for the context's execution status

getRecoveryAction

public ParameterizedAction getRecoveryAction()

copy

public RecoveryGoalContext copy(Context newParent)

Make a copy of this node in the execution tree for simulation purposes

Overrides:

copy in class GoalContext

Parameters:

newParent - new parent context

Returns:
