virtual

Get the HLA object based on its name.

virtual void DtHlaObjectManager::localSubscriptionChanged ( RTI::ObjectClassHandle  handle )

virtual

Called when the local subscription information changes.

protectedvirtual

Call DtHlaObject::callReflect().

Provides friendship towards DtHlaObject to derived classes.

virtual const DtHlaObject* DtHlaObjectManager::processDiscoverObject ( DtHlaObject *  hlaObj )

virtual

Same as above, but takes an existing DtHlaObject.

Called on real discovers and when discovering objects that we register locally, if reflecting is on. returns the instance.

virtual void DtHlaObjectManager::processLocalUpdateRequest ( RTI::ObjectClassHandle  hand, const RTI::AttributeHandleSet &  set  )

virtual

When we are reflecting local data, this function is called to let the object manager know that we have locally requested updates for a class/set of attributes.

As a result, we will call processProvideUpdate for all relevant objects.

virtual void DtHlaObjectManager::processProvideUpdate ( RTI::ObjectHandle  id, const RTI::AttributeHandleSet &  theAttributes  )

virtual

Process RTI's provideUpdate service.

virtual void DtHlaObjectManager::processReflectAttributeValues ( const DtStateMsg &  msg )

virtual

Process an update message.

virtual void DtHlaObjectManager::processRemoveObject ( RTI::ObjectHandle  id )

virtual

Process the removal of an object.

Cleans up the object from reflecting. Called on real removals.

virtual void DtHlaObjectManager::processRemoveObject ( DtHlaObject *  obj )

virtual

Same as above, but takes an existing DtHlaObject.

Called on real removals, and on removals from the discovered list of objects that we are deleting locally, if reflecting is on.

virtual

Called when the local publication information changes.

As a result, we call publicationChanged for all DtHlaObjects that may be affected.

const DtList & DtHlaObjectManager::registeredObjects ( ) const

inlinevirtual

Get the list of all HLA objects registered by the federate.

References DtObjectIdHashlist::list(), and myRegObjectList.

virtual DtHlaObject* DtHlaObjectManager::registerHlaObject ( RTI::ObjectClassHandle  classHand, const char *  name, const DtDDMRegionSet *  regionSet = 0  )

virtual

Use this function instead of the RTI's version to create a new HLA object.

This function calls RTI's registerObjectInstance.

virtual void DtHlaObjectManager::registerHlaObjectWithRegion ( RTI::ObjectClassHandle  classHand, const char *  name, const DtDDMRegionSet &  regionSet, RTI::ObjectHandle &  id  )

virtual

virtual void DtHlaObjectManager::removeAllObjects ( )

protectedvirtual

virtual void DtHlaObjectManager::removeDiscoverObjectCallback ( RTI::ObjectClassHandle  handle, DtDiscoverObjectCb  cb, void *  usr  )

virtual

virtual void DtHlaObjectManager::removeKnownObject ( DtHlaObject *  hlaObj )

protectedvirtual

Call whenever an object is to be deleted, either by delete, or remove.

It removes hlaObj from the set of managed objects, and deletes it.

virtual void DtHlaObjectManager::removeRemoveObjectCallback ( RTI::ObjectHandle  id, DtRemoveObjectCb  cb, void *  usr  )

virtual

virtual void DtHlaObjectManager::setNoRegionsForRegister ( )

virtual

virtual void DtHlaObjectManager::setRegionsForRegister ( int  numAttrs, RTI::AttributeHandle *  attrs, RTI::Region **  regions  )

virtual

By calling setRegionsForRegister, you are telling VR-Link that until you call setRegionsForRegister again (or call setNoRegionsForRegister), VR-Link should use the DDM version of registerObjectInstance whenever it registers an object for you.

The specified arguments will be passed to the RTI. (VR-Link typically registers an object from within a DtObjectPublisher constructor). In order to restore VR-Link back to the default state, when registers are done with the non-DDM version of registerObjectInstance, call setNoRegionsForRegister. attrs is an array of numAttrs attribute handles, regions is an array of numAttrs pointers to RTI::regions. The lifetime of the arrays must extend through the time that the register occurs. Deletion of the arrays is the caller's responsibility. JIMK REVISIT – implement DDM
