static

DtInteraction * DtInteraction::self ( ) const

inlineprotected

Get rid of const-ness on the "this" pointer in order to access non-const functions from const member functions (such as simple accessors).

This should be used sparingly since it bypasses the const protection. Note: This is essentially like an operator and is non-virtual since can't override based on return type. Allows derived classes to also define this member.

virtual void DtInteraction::setConveyedRegion ( const RTI::Region *  region )

virtual

virtual void DtInteraction::setCustomTag ( const DtString &  a_tag )

virtual

Set the user-defined tag.

void DtInteraction::setEventRetractionHandle ( const RTI::EventRetractionHandle &  handle )

inlinevirtual

Get/Set the EventRetractionHandle.

This value is set if the interaction is sent with TSO. If not this value is undefined.

References myRetractionHandle.

virtual void DtInteraction::setExConn ( DtExerciseConn *  exConn, DtInterClassDesc *  classDesc = 0  )

virtual

Sets the interaction's ExerciseConn and class descriptor.

If classDesc is NULL, derived class's versions choose a reasonable default. Without being told what ExConn or class descriptor to use, many of the HLA-specific functions won't work properly. However, it is usually not necessary for application code to call this function, since it is called by DtExerciseConn::send on the outgoing side, and by the DtInteractionFactory on the incoming side.

Reimplemented in DtUnknownInteraction, and DtInteractionWithEncDec.

virtual void DtInteraction::setFedTime ( const RTI::FedTime &  ft )

virtual

This is used for TSO interactions.

It is set with the value of clock()->simTime() before the interaction is sent. When an interaction is received, If its received with a FedTime this will be set.

virtual void DtInteraction::setFromPhvps ( const RTI::ParameterHandleValuePairSet &  pvList )

pure virtual

Set contents from a parameter handle value pair set.

Implemented in DtInteractionWithEncDec, TestSimpleInteraction, and DtUnknownInteraction.

virtual void DtInteraction::setTag ( const DtString &  tag )

virtual

Set the user-defined tag.

static void DtInteraction::setTagIsAsciiTime ( bool  val )

static

Set/Get flag that tells us whether we're using the RPR FOM convention that the UserDefinedTag in updates and interactions represents a DIS-style timestamp.

virtual void DtInteraction::setTimeStamp ( DtTime  time, DtTimeStampType  type = DtTimeStampRelative  )

virtual

Set the time of validity of the message, and whether this represents relative or absolute time.

Time is in seconds, but only time modulo an hour is stored.

virtual const DtString& DtInteraction::tag ( ) const

virtual

Get the user-defined tag.

static bool DtInteraction::tagIsAsciiTime ( )

static

virtual DtTime DtInteraction::timeStamp ( ) const

virtual

Return the time of validity of the message (in seconds past an hour) as set by setTimeStamp.

virtual DtTimeStampType DtInteraction::timeStampType ( ) const

virtual

Return the type of the time stamp.
