Constructor & Destructor Documentation

ShapePositionFunctor()

template<typename TShape >

DGtal::functors::ShapeGeometricFunctors::ShapePositionFunctor< TShape >::ShapePositionFunctor ( ConstAlias< Shape >  aShape = 0 )

inline

Constructor. A shape may also be attached at construction.

Parameters

aShape

the shape of interest. The alias can be secured if a some counted pointer is handed.

Definition at line 77 of file ShapeGeometricFunctors.h.

: myShape( aShape ) {}

attach()

template<typename TShape >

void DGtal::functors::ShapeGeometricFunctors::ShapePositionFunctor< TShape >::attach ( ConstAlias< Shape >  aShape )

inline

Attach a shape.

Parameters

aShape

the shape of interest. The alias can be secured if a some counted pointer is handed.
