Detailed Description

A DtTaskMsg is a DtRadioMsg with a pointer to a task.

The type of the taskMsg is just the type of the task.

Constructor & Destructor Documentation

DtTaskMessage::DtTaskMessage

(

)

default constructor

DtTaskMessage::DtTaskMessage

(

const DtTaskMessage &

orig

)

virtual DtTaskMessage::~DtTaskMessage ( )

virtual

Destructor; does not destroy task, unless it created it (copy constructor; assignment operator; or setFromNet()).

Member Function Documentation

const DtTaskMessage& DtTaskMessage::operator= ( DtTaskMessage &  orig )

protected

virtual DtSimTask* DtTaskMessage::task ( ) const

virtual

Returns a pointer to the task this message is conveying.

virtual void DtTaskMessage::setTask ( DtSimTask *  task )

virtual

N.B.

: This function USED TO clone the task passed as an argument. However, for performance reasons, it has been modified to just keep a pointer to the task. This means that it is the caller's responsibility to ensure that the lifetime of the task goes beyond the lifetime of the message. For example, this previously acceptable code will now FAIL:

DtSimTask* task = new DtMoveToTask; DtTaskMessage* message = new DtTaskMessage; task->setControlPtName("A Waypoint"); message->setTask(task); delete task; vrfObject()->radio()->sendToNet(message); ...

virtual bool DtTaskMessage::independentlyTasked ( ) const

virtual

Indicates whether task issued intended to be executed independently by the recipient, or as part of an aggregate.

virtual void DtTaskMessage::setIndependentlyTasked ( bool  yesNo )

virtual

virtual void DtTaskMessage::setTaskId ( int  id )

virtual

Identifier used to associated task complete the original task message.

Each task gets a task ID when it starts being executed. The user should never have to set this manually.

virtual int DtTaskMessage::taskId ( ) const

virtual

Identifier used to associated task complete the original task message.

Each task gets a task ID when it starts being executed. The user should never have to set this manually.

virtual void DtTaskMessage::setSubtaskId ( int  id )

virtual

Deprecated:

As of VR-Forces 3.12. Call setTaskId() and taskId() instead.

virtual int DtTaskMessage::subtaskId ( ) const

virtual

Deprecated:

As of VR-Forces 3.12. Call setTaskId() and taskId() instead.

virtual void DtTaskMessage::setTaskTrackingNumber ( int  n )

virtual

This value is the same as the taskTrackingNumber passed in the original task message that started the task.

This is designed for uses such as an aggregate starting issuing tasks to a subordinate, and providing unique identifiers to the tasks so their completion can be tracked.

Note

This is different from taskId, since taskId is assigned by the entity carrying out the task, can cannot be known at the time of issuing the task.

virtual int DtTaskMessage::taskTrackingNumber ( ) const

virtual

This value is the same as the taskTrackingNumber passed in the original task message that started the task.

This is designed for uses such as an aggregate starting issuing tasks to a subordinate, and providing unique identifiers to the tasks so their completion can be tracked.

Note

This is different from taskId, since taskId is assigned by the entity carrying out the task, can cannot be known at the time of issuing the task.

virtual int DtTaskMessage::contentCategoryType ( ) const

virtual

Returns the string type identifier for the message type, DtTaskMessageType (defined in taskTypes.h).

If you override this class, you should override this member function to return its own unique string type.

Implements DtVrfObjectMessage.

virtual const DtSimTaskMessageType& DtTaskMessage::contentType ( ) const

virtual

Returns

The type of task contained in this message.

virtual DtSimMessage* DtTaskMessage::clone ( ) const

virtual

Required override.

Clones itself and the task it points to. Returns a newly created copy of itself. The contents of the class are cloned from this instance, including the task it contains. Derived classes should override this member function to return a cloned copy of the derived type.

Implements DtSimMessage.

virtual int DtTaskMessage::netRepSize ( ) const

virtual

Overrides the base class DtVrfObjectMessage netRepSize().

This calls down to the base class to get the size of the header created by the base, and then adds any task, set data, or report contents.

Reimplemented from DtVrfObjectMessage.

virtual bool DtTaskMessage::setFromNet ( const char *  networkBuffer, unsigned  contentSize  )

virtual

Extracts the task type, creates the task (using the task factory), and then tells the task to fill itself in from the network buffer.

Reimplemented from DtVrfObjectMessage.

virtual bool DtTaskMessage::setToNet ( )

virtual

Fill in our task type, tell the task to fill itself out, and then copy its buffer into ours.

Reimplemented from DtVrfObjectMessage.

virtual void DtTaskMessage::printDataToString ( DtString &  str )

virtual

Print message.

Reimplemented from DtVrfObjectMessage.

static DtVrfObjectMessage* DtTaskMessage::creator ( )
