Detailed Description

Description: Objects may contain a collection of other objects, such as overlays or pseudo-aggregate entities.

This class defines an interface for maintaining a collection of these subObjects. What's actually stored is a DtList of the object DtEntityIdentifiers. The iterator that can be spawned will iterate through DtEntityIdentifiers, look up the objects in the object mgr. and return pointers to them.

const DtSubordinateManager& DtSubordinateManager::operator=

orig

)

Assignment Operator.

virtual DtSubordinateManager* DtSubordinateManager::clone ( ) const

virtual

Creates a new manager calling the copy constructor and returns the result.

Reimplemented in DtVrfSubordinateManager.

virtual bool DtSubordinateManager::addSubordinate ( DtVrfObject *  subordinate, int  designator = 0  )

virtual

All adding subordinate calls will fail if the specified designator is already in use.

0 is the only designator which is allowed for multiple subordinates. (0 implies no designator). Adds an object as a subordinate.

virtual bool DtSubordinateManager::addSubordinateBefore ( DtVrfObject *  subordinate, DtVrfObject *  beforeObject, int  designator = 0  )

virtual

virtual bool DtSubordinateManager::addSubordinateAfter ( DtVrfObject *  subordinate, DtVrfObject *  afterObject, int  designator = 0  )

virtual

note that if the afterObject is not found, the object is added to the end of the list

virtual void DtSubordinateManager::removeSubordinate ( DtVrfObject *  subordinate )

virtual

Removes given object as a subordinate.

virtual void DtSubordinateManager::removeAllSubordinates ( )

virtual

note that if the beforeObject is not found, the object is added to the end of the list

virtual int DtSubordinateManager::numSubordinates ( ) const

virtual

Returns the number of subrodinates managed by this object.

virtual DtVrfObject* DtSubordinateManager::firstSubordinate ( ) const

virtual

useful to be able to get the first or last in the list without needed to spawn an iterator.

virtual DtVrfObject* DtSubordinateManager::lastSubordinate ( ) const

virtual

virtual bool DtSubordinateManager::isSubordinate ( const DtEntityIdentifier &  id ) const

virtual

Returns true if this object is listed in this subordinate manager.

virtual bool DtSubordinateManager::isSubordinate ( DtVrfObject *  simObj ) const

virtual

const DtKeyedVrfObjectIterator& DtSubordinateManager::iterator

(

)

const

allocates and returns an iterator to iterate over this subObject list.

It is the responsibility of the caller to delete this iterator when finished with it.

virtual int DtSubordinateManager::designatorForSubordinate ( DtVrfObject *  subordinate ) const

virtual

Returns the designator number for a subordinate in the list.

Note that 0 is the only designator more than one entity can have.

virtual int DtSubordinateManager::designatorForSubordinate ( const DtEntityIdentifier &  id ) const

virtual

virtual DtVrfObject* DtSubordinateManager::subordinateForDesignator ( int  designator ) const

virtual

Returns the subordinate with a particular designator.

Does not work for designator = 0

virtual bool DtSubordinateManager::setDesignator ( const DtEntityIdentifier &  id, int  designator  )

virtual

Sets the designator of a subordinate to the specified value.

This call will fail (and return false) if the specified designator is already in use. 0 is the only designator that can be used by more that one subordinate.

virtual bool DtSubordinateManager::setDesignator ( DtVrfObject *  subordinate, int  designator  )

virtual

virtual int DtSubordinateManager::firstAvailableDesignator ( int  start = 1 ) const

virtual

Returns the lowest unused designator.

virtual int DtSubordinateManager::maxUsedDesignator ( ) const

virtual

Returns the highest used designator.

(there may be holes in the sequence)

virtual void DtSubordinateManager::reorderToDesignatorOrder ( )

virtual

Causes the order of the subordinate list to be in ascending designator order.

Any with no designator (designator = 0) will appear in an undefined order at the end of the list.

virtual void DtSubordinateManager::designatorOrderedList ( std::vector< DtEntityIdentifier > &  designatorOrderedList ) const

virtual

Returns list of DtEntityIdentifiers, ordered from lowest to highest designator.

virtual void DtSubordinateManager::setSubordinateOrder ( const std::vector< DtEntityIdentifier > &  orderedList )

virtual

Removes all subordinates from the subordinate manager and then adds new subordinates in the order given by orderedList.

virtual void DtSubordinateManager::addSubordinatesChangedCallback ( DtSubordinateManagerCallbackFcn  fcn, void *  userData  )

virtual

Registers callback for notification of any change to the subordinates (addition, removal, reordering).

virtual void DtSubordinateManager::removeSubordinatesChangedCallback ( DtSubordinateManagerCallbackFcn  fcn, void *  userData  )

virtual

Removes callback for notification of any change to the subordinates (addition, removal, reordering).

virtual int DtSubordinateManager::nextAvailableDesignator ( int  cur = 0 ) const

virtual

Returns the highest next designator based on the designator table and the current designator assigned.

void DtSubordinateManager::copySubordinateList ( const DtList &  list )

void DtSubordinateManager::emptySubordinateList ( )

DtListItem* DtSubordinateManager::findSubordinateItem ( const DtEntityIdentifier &  id ) const

DtList DtSubordinateManager::mySubordinateList

protected

The list of entity id's is kept since order is important.

DtEntityIdIntAssociationList DtSubordinateManager::myDesignatorTable

protected

The table of entity id's and designators is used to associate a designator with each entity.

Mutator functions in this class ensure that an entity appears in both lists.

std::vector<DtSubordinateManagerCallbackInfo> DtSubordinateManager::mySubordinatesChangedCallbackList

protected

List of DtSubordinateCallbackFcn*s.

Clients register callback functions on this list for notification when the list of subordinates changed for some reason (addition, removal, list ordering).
