typedef SharedObj VRS::SharedObj::VRS_ThisClass

Member Function Documentation

virtual bool VRS::SharedObj::isEqual ( const SharedObj *  other  )  const [virtual]

The isEqual() method can be used to compare for object equality.

< The constructor sets initially the reference counter to zero and assigns the current time stamp to the object. Two objects should be considered equal if they are located at the same address (if they are identical) or if all there state member variables have equal state. Override the "operator==" in derived classes to refine/define the equality definition for the corresponding class.

static bool VRS::SharedObj::IsEqual ( const SharedObj *  obj1,
const SharedObj *  obj2 
) [static]

bool VRS::SharedObj::operator== ( const SharedObj &  other  )  const

static const ClassInfo* VRS::SharedObj::ClassInfoVRS (  )  [static]

Reimplemented in VRS::SceneSpy.

virtual const ClassInfo* VRS::SharedObj::classInfoVRS (  )  const [virtual]

For internal use in VRS.

Reimplemented in VRS::SceneSpy.

static const ID& VRS::SharedObj::ClassNameVRS (  )  [static]

Reimplemented in VRS::SceneSpy.

const ID& VRS::SharedObj::classNameVRS (  )  const

bool VRS::SharedObj::isA ( const ID &  id  )  const

Shared objects provide runtime type information. The static method `ClassName' returns the (unique) class name string. `className' returns the class name of an object. `isA' returns true if the given name corresponds to one of the subclasses.

void VRS::SharedObj::ref ( const void *  debugPointerHolder = NULL  )  const

void VRS::SharedObj::unref ( const void *  debugPointerHolder = NULL  )  const

long VRS::SharedObj::references (  )  const

Shareable objects maintain a reference counter. Objects which hold a reference or pointer to a shareable object increment its reference counter. If the object is not refered any more, the reference counter must be decremented. If the reference counter gets zero, the object is deleted.

void VRS::SharedObj::trackReferences (  ) 

void VRS::SharedObj::outputReferences (  )  const

static void VRS::SharedObj::outputAllTrackedObjectReferences (  )  [static]

!!! DEBUG mode only !!! trackReferences() marks an object for tracking the source code locations of all pointers referencing the object. ouputReferences() outputs the stored locations to the error output stream. outputAllTrackedObjectReferences() outputs the stored locations of all tracked objects to the error output stream. !!! DEBUG mode only !!!

void VRS::SharedObj::setObjectName ( const char *  objName  ) 

void VRS::SharedObj::setObjectName ( const std::string &  objName  ) 

std::string VRS::SharedObj::getObjectName (  )  const

static SO<SharedObj> VRS::SharedObj::getObjectByName ( const std::string &  objName  )  [static]

Objects can be assigned a textual name. If an object has no name an empty string is returned by the method getObjectName(). The named objects can be retrieved again by calling the static method getObjectByName(), which returns the last object that got "objName" assigned or NULL if no object with such a name exists.

void VRS::SharedObj::setClientData ( void *  clientData  ) 

void* VRS::SharedObj::getClientData (  )  const

Objects can be assigned unspecified client data.

virtual const TransactionNo& VRS::SharedObj::lastTransactionNo (  )  const [virtual]

Reimplemented in VRS::GuardedCastIterator< TO, FROM >, VRS::IndexedIterator< T, INDEX >, VRS::RepeatIterator< T >, VRS::ReplicateIterator< T >, VRS::ReverseIterator< T >, VRS::SkipIterator< T >, VRS::SubIterator< T >, VRS::TypeCastIterator< TO, FROM >, and VRS::DecoratedImage.

static const TransactionNo& VRS::SharedObj::currentTransactionNo (  )  [static]

VRS maintains a global system wide transaction number. Each modification applied to a shared object increments this counter. Each shared object stores the transaction number of its last modification. This way, we can determine if an object has been modified before another object. 'modified' assigns the current transaction number to the object and increments the transaction number. 'lastTransactionNo' returns transaction number of the last modification of the object. 'currentTransactionNo' returns the current transaction number.

void VRS::SharedObj::unregisterDestructionCB ( SO< Callback1< SharedObj * > >  cb  ) 

void VRS::SharedObj::unregisterModificationCB ( SO< Callback1< SharedObj * > >  cb  ) 

`Callback' objects can observe object modifications and the destruction of a shared object. In all cases, the `callback' method of the corresponding registered callbacks will be called. The argument for the callback is a pointer to the shared object which has been modified/is going to be destructed. The destruction-callback will be called immediately BEFORE object-destruction, so all member-data can still be inspected!

bool VRS::SharedObj::unregisterCB ( const ID &  service,

Unregisters the given callback for the given service. Returns, if the given callback was registered for the service.
