Detailed Description

Provide the ability to use a recorded DIS stream (playback files) as an input stream.

Entities that are created from this device are a sort of hybrid entity. In many regards they are treated as local entities, that is they have Entity State PDU's written to output streams. But their motion comes from Entity State PDU's read from the file (so they are like 'external' entities in this regard).

This was initially created so we could read DIS recording files produced by SLAMEM. It has a good traffic model and it was easier to simply read the generated data rather than trying to replicate what they do.

Note: : At the current time only Entity State PDU's are used from the file. All other PDU's are ignored.

Member Function Documentation

◆ EntityDeleted()

void WsfDisPlaybackDevice::EntityDeleted ( const DisEntityId & aEntityId )

static

Update the list of deleted entities. This is called by WsfDisInterface::DeletePlatform() whenever a platform is deleted.

References IsPlaybackEntity().

◆ GetPdu()

DisPdu * WsfDisPlaybackDevice::GetPdu ( DisPduFactory * aPduFactoryPtr )

overridevirtual

Reimplemented from WsfDisDevice.

◆ IsPlaybackEntity()

bool WsfDisPlaybackDevice::IsPlaybackEntity ( const DisEntityId & aEntityId )

inlinestatic

the supplied entity ID associated with a playback entity.

References cMAX_PLAYBACK_SITE, and cMIN_PLAYBACK_SITE.

Referenced by EntityDeleted(), WsfDisInterface::ExtrapolatePlatformState(), WsfDisPlatform::PlatformInitialized(), WsfDisEntityState::Process(), WsfDisPlatform::SetEntityState(), WsfDisMover::Update(), and WsfDisPlatform::WsfDisPlatform().

◆ PreparePlaybackPlatform()

void WsfDisPlaybackDevice::PreparePlaybackPlatform	(	double	aSimTime,
		WsfPlatform *	aPlatformPtr,
		DisEntityState *	aEntityPtr )

static

Prepare a playback platform for use.

This is called by WsfDisInterface::AddExternalPlatform after the platform has been instantiated but before it is added to the simulation.

Parameters

aSimTime	The current simulation time.
aPlatformPtr	The platform about to be added to the simulation.
aEntityPtr	The entity state that is associated with the platform.
