Detailed Description

template<typename T>
struct DGtal::CBidirectionalSegmentComputer< T >

Aim: Defines the concept describing a bidirectional segment computer, ie. a model of CSegment that can extend itself in the two possible directions.

Description of concept 'CBidirectionalSegmentComputer'

Refinement of CForwardSegmentComputer

Associated types : the same as CForwardSegmentComputer

Notation

• X : A type that is a model of CBidirectionalSegmentComputer
• x : object of type X

Definitions
