unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) const [inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) [inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

Turn debugging output off.

virtual void itk::Object::DebugOn (  )  const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete (  )  [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

virtual Matrix< double,::itk::GetDimension< TInputImage::PixelType >::Dimension,::itk::GetImageDimension< TInputImage >::ImageDimension > itk::ImageFunction< TInputImage , Matrix< double,::itk::GetDimension< TInputImage::PixelType >::Dimension,::itk::GetImageDimension< TInputImage >::ImageDimension > , TCoordRep >::Evaluate ( const PointType point  )  const [pure virtual, inherited]

virtual OutputType itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::Evaluate ( const PointType point  )  const [inline, virtual]

Evalulate the image derivative by central differencing at non-integer positions.

No bounds checking is done. The point is assume to lie within the image buffer.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.

Command* itk::Object::GetCommand ( unsigned long  tag  )  [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::Object::GetDebug (  )  const [inherited]

Get the value of the debug flag.

) const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::ImageFunction< TInputImage, Matrix< double,::itk::GetDimension< TInputImage::PixelType >::Dimension,::itk::GetImageDimension< TInputImage >::ImageDimension >, TCoordRep >.

virtual void itk::LightObject::PrintTrailer ( std::ostream &  os,
Indent  indent 
) const [protected, virtual, inherited]

Define the type of the reference count according to the target. This allows the use of atomic operations

virtual void itk::Object::Register (  )  const [virtual, inherited]

Increase the reference count (mark as used by another object).

Reimplemented from itk::LightObject.

void itk::Object::RemoveAllObservers (  )  [inherited]

Remove all observers .

void itk::Object::RemoveObserver ( unsigned long  tag  )  [inherited]

Remove the observer with this tag value.

void itk::Object::SetDebug ( bool  debugFlag  )  const [inherited]

Set the value of the debug flag. A non-zero value turns debugging on.

static void itk::Object::SetGlobalWarningDisplay ( bool  flag  )  [static, inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

Referenced by itk::Object::GlobalWarningDisplayOff(), and itk::Object::GlobalWarningDisplayOn().

virtual void itk::ImageFunction< TInputImage , Matrix< double,::itk::GetDimension< TInputImage::PixelType >::Dimension,::itk::GetImageDimension< TInputImage >::ImageDimension > , TCoordRep >::SetInputImage ( const InputImageType *  ptr  )  [virtual, inherited]

Set the input image.

Warning:
this method caches BufferedRegion information. If the BufferedRegion has changed, user must call SetInputImage again to update cached values.
void itk::Object::SetMetaDataDictionary ( const MetaDataDictionary rhs  )  [inherited]
Returns:
Set the MetaDataDictionary
virtual void itk::Object::SetReferenceCount ( int   )  [virtual, inherited]

Sets the reference count (use with care)

Reimplemented from itk::LightObject.

template<class TInputImage , class TCoordRep = float>
virtual void itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::SetUseImageDirection ( bool  _arg  )  [virtual]

The UseImageDirection flag determines whether image derivatives are computed with respect to the image grid or with respect to the physical space. When this flag is ON the derivatives are computed with respect to the coordinate system of physical space. The difference is whether we take into account the image Direction or not. The flag ON will take into account the image direction and will result in an extra matrix multiplication compared to the amount of computation performed when the flag is OFF. The default value of this flag is the same as the CMAKE option ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE (i.e ON by default when ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE is ON, and OFF by default when ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE is OFF).

virtual void itk::Object::UnRegister (  )  const [virtual, inherited]

Decrease the reference count (release by another object).

Reimplemented from itk::LightObject.

template<class TInputImage , class TCoordRep = float>
virtual void itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::UseImageDirectionOff (  )  [virtual]

Standard class typedefs.

template<class TInputImage , class TCoordRep = float>
virtual void itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::UseImageDirectionOn (  )  [virtual]

Standard class typedefs.
