Detailed Description

The attachment manager maintains a tree of objects for the state repository class.

These objects are represented as other DtSimObjectStateRepositorys. Objects that need to maintain geometry with respect to some parent geometry use this manager.

Creation of the state repositories for the attached objects is done outside the manager; objects are attached and detached as required. The manager can provide iterators to traverse just the top level SRs it maintains or the entire forest it represents.

virtual

Destructor.

Member Function Documentation

const DtAttachmentManager& DtAttachmentManager::operator=

(

const DtAttachmentManager &

orig

)

Assignment Operator.

virtual DtAttachmentManager* DtAttachmentManager::clone ( ) const

virtual

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

Reimplemented in DtVrfAttachmentManager.

virtual void DtAttachmentManager::attach ( DtSimObjectStateRepository *  obj )

virtual

Attach a part.

virtual void DtAttachmentManager::detach ( DtSimObjectStateRepository *  obj )

virtual

Detach a part.

virtual int DtAttachmentManager::numAttachments ( ) const

virtual

Returns the number of SRs attached.

Referenced by DtRecursiveStateRepositoryIterator::next().

virtual const DtSimObjectStateRepositoryIterator& DtAttachmentManager::iterator ( ) const

virtual

Spawns an iterator that just iterates over the elements in this manager, but does not go down to any of the children.

virtual DtRecursiveStateRepositoryIterator* DtAttachmentManager::spawnRecursiveIterator ( ) const

virtual

Spawns an iterator that iterates over the elements in this manager, and all their children, sub children, etc.

. The caller MUST DELETE the iterator when done using it!

virtual void DtAttachmentManager::parentKinematicsChanged ( )

virtual

tell all elements that the kinematic state of the parent has changed so that they can invalidate cached vectors in the world coord system

virtual void DtAttachmentManager::setCoordinateSystem ( const Coordinate_System *  coordinateSystem )

virtual

const DtList& DtAttachmentManager::elements ( ) const

inline

Referenced by DtRecursiveStateRepositoryIterator::next().

void DtAttachmentManager::emptyList ( )

protected

Clean out the DtList of SR pointers, deleting as we go.

void DtAttachmentManager::copyList ( const DtList &  otherElements )

protected

Copy a list of state repositories.

Each repository is cloned. Used by assignment operator and copy constructor.

static void DtAttachmentManager::simObjectRepositoryAboutToBeDeleted ( DtSimObjectStateRepository *  , void *    )

staticprotected

Callback made when a state rep is deleted, and, if it is still in the list, remove it as removing it when this manager is removed will also delete it.

Safeguard for double deletion
