Member Function Documentation

appendPoint()

template<class T , class U = T>

virtual void TrajColl::Interpolator< T, U >::appendPoint ( const std::pair< double, T > &  point )

pure virtual

Add point.

Parameters

point

time and value

Note

Interpolator::calcCoeff should be called before calling Interpolator::operator().

Implemented in TrajColl::BangBangInterpolator< T, U >, and TrajColl::CubicInterpolator< T, U >.

calcCoeff()

template<class T , class U = T>

virtual void TrajColl::Interpolator< T, U >::calcCoeff ( )

pure virtual

Calculate coefficients.

Implemented in TrajColl::BangBangInterpolator< T, U >, and TrajColl::CubicInterpolator< T, U >.

clearPoints()

template<class T , class U = T>

virtual void TrajColl::Interpolator< T, U >::clearPoints ( )

inlinevirtual

Clear points.

Reimplemented in TrajColl::BangBangInterpolator< T, U >.

Definition at line 33 of file Interpolator.h.

clone()

template<class T , class U = T>

virtual std::shared_ptr<Interpolator<T, U> > TrajColl::Interpolator< T, U >::clone ( ) const

pure virtual

Clone this instance and get shared pointer.

derivative()

template<class T , class U = T>

virtual U TrajColl::Interpolator< T, U >::derivative ( double  t, int  order = 1  ) const

pure virtual

Calculate the derivative of interpolated value.

Parameters

t	time
order	derivative order

It is assumed that interpolateDerivative() returns zero if derivative order is greater than or equal to 2.

Implemented in TrajColl::BangBangInterpolator< T, U >, and TrajColl::CubicInterpolator< T, U >.

endTime()

template<class T , class U = T>

double TrajColl::Interpolator< T, U >::endTime ( ) const

inline

Get end time.

Definition at line 68 of file Interpolator.h.

operator()()

template<class T , class U = T>

virtual T TrajColl::Interpolator< T, U >::operator() ( double  t ) const

pure virtual

Calculate interpolated value.

Parameters

t

time

Implemented in TrajColl::BangBangInterpolator< T, U >, and TrajColl::CubicInterpolator< T, U >.

points()

template<class T , class U = T>

const std::map<double, T>& TrajColl::Interpolator< T, U >::points ( ) const

inline

Get points.

Definition at line 74 of file Interpolator.h.

startTime()

template<class T , class U = T>

double TrajColl::Interpolator< T, U >::startTime ( ) const

inline

Get start time.

Definition at line 62 of file Interpolator.h.
