Constructor Details

RootContext

public RootContext(ActionConstraints constraints,
 StateMachine sm)

RootContext constructor

Parameters:

constraints - root action constraints (applies to all child contexts)

sm - state machine for root context

RootContext

public RootContext(ActionConstraints constraints,
 StateMachine sm,
 ExecutionType executionType)

RootContext constructor

Parameters:

constraints - root action constraints (applies to all child contexts)

sm - state machine for root context

Method Details

createSimulationRoot

public RootContext createSimulationRoot(StateMachine sm,
 ExecutionType executionType)

RootContext for simulations

Parameters:

sm - state machine for simulation

executionType - execution type for the new root (should be some simulation state)

getNextStepForType

protected Context getNextStepForType()

Description copied from class: Context

Get the next step (i.e., context) to be executed. Returns null if there are no more steps. TODO: remove this method

Overrides:

getNextStepForType in class Context

Returns:

setStatus

public void setStatus(ActionStatus eStatus,
 Justification justification)

Description copied from class: Context

Set the ActionStatus and Justification for the status. NOTE: Classes overriding this method must call super.setStatus(status, justification) inside their overriding method to actually set the status and justification. Using the convenience method setStatus(status) will cause an infinite loop, and also abandon the Justification.

Overrides:

setStatus in class Context

prune

public void prune(long historyLength)

Prune children that are terminated. TODO: use historyLength

Parameters:

historyLength - ms of history to keep

copy

public RootContext copy(Context newParent)

Description copied from class: Context

deep copy of the context, its status, and its children

Specified by:

copy in class Context

Parameters:

newParent - parent to attach the copied context too

Returns:

the copied context
