Member Function Documentation

virtual void DtPlan::init ( )

virtual

The init function must be called after any non-copy constructor!

virtual DtPlan* DtPlan::clone ( const DtString &  name, const DtString &  planName, DtReaderWriterRegistry *  parentRegistry = NULL  ) const

virtual

Returns a newly created copy of ourself.

name is the DtReaderWriter name of the plan.

DtPlan& DtPlan::operator=

(

const DtPlan &

orig

)

Note: this will NOT copy the DtSimPlanManager pointer, and will only copy the planName if *this is not currently registered with a DtSimPlanManager (because either the DtSimPlanManager pointer is NULL or the current planName is empty).

virtual bool DtPlan::operator== ( const DtPlan &  orig ) const

virtual

Equality operator.

virtual DtString DtPlan::planName ( ) const

virtual

virtual void DtPlan::setPlanName ( const DtString &  name )

virtual

virtual const DtString& DtPlan::objectName ( ) const

virtual

Get/set the object name of entity associated with this plan.

virtual void DtPlan::setObjectName ( const DtString &  objectName )

virtual

virtual bool DtPlan::objectNameSpecified ( ) const

virtual

true if the object name was specified in the RW structure.

virtual void DtPlan::setPlanExecutor ( DtPlanExecutor *  planExecutor )

virtual

Get a pointer to the sim manager.

virtual DtPlanExecutor* DtPlan::planExecutor ( ) const

virtual

virtual void DtPlan::enableExecutionState ( )

virtual

Enable/disable plan execution state.

Plan will not start or advance through statements unless execution state is enabled.

virtual void DtPlan::disableExecutionState ( )

virtual

virtual bool DtPlan::executionState ( ) const

virtual

virtual void DtPlan::awaitingTask ( )

virtual

Sets our awaiting task flag (it will be handled in processAwaitingTask(), called from tick if/when plan execution state is enabled.

virtual bool DtPlan::isAwatingTask ( ) const

virtual

Returns

the current value of myAwaitingTaskFlag.

virtual void DtPlan::pushExecutionStack ( )

virtual

When a retasking trigger fires, it first calls pushExecutionStack on the DtPlan.

This has the effect of duplicating the currentStmt index at the top of the stack. It does not, of itself, cause any new statements to get executed or sent to the entity. It is assumed that this call will be followed by a call to executeTrigger(), or at least setCurrentStmt().

virtual void DtPlan::popExecutionStack ( bool  forceStep = false )

virtual

When a retasking trigger completes, it calls popExecutionStack on the DtPlan.

This has the effect of popping the execution stack back to the statement that was interrupted by the trigger. If the forceStep parameter is true, this will step to the statement following the one on the stack. If false, then the plan will check to see if the new top statement is still executing. If so, it will continue with that statement, otherwise it will step to the next statement.

virtual void DtPlan::executeTrigger ( DtWhenBlock *  whenBlock )

virtual

When a DtSimTrigger gets executed, it calls the executeTrigger function which begins execution of the whenBlock.

virtual void DtPlan::executeBlock ( DtSimBlock *  block )

virtual

Begin execution of a block of tasks.

virtual bool DtPlan::taskRequestPending ( ) const

virtual

Get the TaskRequestPending flag.

virtual void DtPlan::setTaskRequestPending ( bool  newValue = true )

Uses myPlanExecutor to evaluate the conditional expression.

False is returned if there is not plan executor.

virtual

Returns

True if the plan has been abandoned.

Note

The plan will also return true of isComplete() if it has been abandoned.

virtual void DtPlan::setIsAbandoned ( bool  v )

virtual

Member Data Documentation

DtRwBoolean DtPlan::myTaskRequestPending

protected

The TaskRequestPending flag is set to true when an Entity requests a new task, and is cleared when a new task is sent by the Plan engine.

There may be any number of non-task statements processed between these two events. Further processing of the entity's plan is paused when this flag is cleared.

DtPlanBlock* DtPlan::myMainBlock

protected

The main Block is the top-level Block of the plan and is the only Block that is considered to be "owned" by this DtPlan object.

DtList DtPlan::myExecutionStack

protected

The top of the execution stack is the Plan's current statement (fetched with currentStmt()).

Whenever a retasking trigger fires, it pushes this stack down so that the Plan can pick up where it left off at the end of the trigger.

DtRwBoolean DtPlan::myIsComplete

protected

myIsComplete Disables awaitingTask() and causes it to emit continuous Wait tasks.

DtRwBoolean DtPlan::myAbandoned

protected
