Detailed Description

template<typename T>
struct DGtal::concepts::CDynamicSegmentComputer< T >

Aim: Defines the concept describing a dynamic segment computer,
ie. a model of CSegment that can extend and retract itself (in the direction that is relative to the underlying iterator).

Description of concept 'CDynamicSegmentComputer'

Refinement of CForwardSegmentComputer

Associated types the same as CForwardSegmentComputer

Notation

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

Definitions

Valid expressions and

Name	Expression	Type requirements	Return type	Precondition	Semantics	Post condition	Complexity
Retraction	x.retractBack()		bool		returns 'tru' if ++x.begin() != x.end() (and increments the begin iterator), 'false' otherwise
