Detailed Description

template<typename Point1, typename Point2, typename Point3, typename Value>
struct Acts::detail::can_interpolate< Point1, Point2, Point3, Value >

check types for requirements needed by interpolation

Template Parameters
Point1type for specifying geometric positions
Point2type for specifying geometric positions
Point3type for specifying geometric positions
Valuetype of values to be interpolated

This helper struct provides compile-time information whether the provided Point and Value types can be used in the Acts::interpolate function.

The following boolean variable

is true if all Point types and Value fulfill the type requirements for being used in the interpolation function, otherwise it is false. This expression can be employed in std::enable_if_t to use SFINAE patterns to enable/disable (member) functions.
