Detailed Description

template<class Value>
class Eagle::Interpol< Value >

Interpolation of certain values.

Member Function Documentation

getKeyID()

template<class Value >

int Eagle::Interpol< Value >::getKeyID ( double  t ) const

inline

Get the number of the corresponding key frame, given an interpolation value.

Note that this function is slow, as it has to perform a linear search. Using getInterval() is faster if the absolut index is not required.
