typedef Self

Standard class typedefs

typedef Superclass

typedef DataObject shapeworks::Observer::Superclass;

typedef Pointer

typedef itk::SmartPointer<Self> shapeworks::Observer::Pointer;

Public Functions Documentation

function itkNewMacro

itkNewMacro(
    Self 
)

Method for creation through the object factory.

function itkTypeMacro

itkTypeMacro(
    Observer ,
    DataObject 
)

Run-time type information (and related methods).

function DomainAddEventCallback

inline virtual void DomainAddEventCallback(
    Object * ,
    const itk::EventObject & 
)

Reimplemented by: shapeworks::GenericContainerArray::DomainAddEventCallback, shapeworks::GenericContainerArray::DomainAddEventCallback, shapeworks::LegacyShapeMatrix::DomainAddEventCallback, shapeworks::LinearRegressionShapeMatrix::DomainAddEventCallback, shapeworks::MixedEffectsShapeMatrix::DomainAddEventCallback, shapeworks::ShapeGradientMatrix::DomainAddEventCallback, shapeworks::ShapeMatrix::DomainAddEventCallback

Callbacks that may be defined by a subclass. If a subclass defines one of these callback methods, the corresponding flag in m_DefinedCallbacks should be set to true so that the ParticleSystem will know to register the appropriate event with this method.

function TransformSetEventCallback

inline virtual void TransformSetEventCallback(
    Object * ,
    const itk::EventObject & 
)

function PrefixTransformSetEventCallback

inline virtual void PrefixTransformSetEventCallback(
    Object * ,
    const itk::EventObject & 
)

function PositionSetEventCallback

inline virtual void PositionSetEventCallback(
    Object * ,
    const itk::EventObject & 
)

Reimplemented by: shapeworks::LegacyShapeMatrix::PositionSetEventCallback, shapeworks::LinearRegressionShapeMatrix::PositionSetEventCallback, shapeworks::MixedEffectsShapeMatrix::PositionSetEventCallback, shapeworks::ShapeGradientMatrix::PositionSetEventCallback, shapeworks::ShapeMatrix::PositionSetEventCallback

function PositionAddEventCallback

inline virtual void PositionAddEventCallback(
    Object * ,
    const itk::EventObject & 
)

Reimplemented by: shapeworks::GenericContainerArray::PositionAddEventCallback, shapeworks::GenericContainerArray::PositionAddEventCallback, shapeworks::LegacyShapeMatrix::PositionAddEventCallback, shapeworks::LinearRegressionShapeMatrix::PositionAddEventCallback, shapeworks::MixedEffectsShapeMatrix::PositionAddEventCallback, shapeworks::ShapeGradientMatrix::PositionAddEventCallback, shapeworks::ShapeMatrix::PositionAddEventCallback

function PositionRemoveEventCallback

inline virtual void PositionRemoveEventCallback(
    Object * ,
    const itk::EventObject & 
)

Reimplemented by: shapeworks::GenericContainerArray::PositionRemoveEventCallback, shapeworks::GenericContainerArray::PositionRemoveEventCallback, shapeworks::LegacyShapeMatrix::PositionRemoveEventCallback, shapeworks::LinearRegressionShapeMatrix::PositionRemoveEventCallback, shapeworks::MixedEffectsShapeMatrix::PositionRemoveEventCallback, shapeworks::ShapeGradientMatrix::PositionRemoveEventCallback, shapeworks::ShapeMatrix::PositionRemoveEventCallback

function set_suspended

inline void set_suspended(
    bool suspended
)

Stop this observer from reacting to events. The correspondence matrices lay themselves out assuming every shape holds the same number of particles, which is not true while particles are still being spread over a single reference shape. Suspending them until every shape has been populated avoids that, and a later SynchronizePositions() brings them back up to date.

function is_suspended

inline bool is_suspended() const

function PrintSelf

inline void PrintSelf(

) const
