Detailed Description

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

Aim: Represents types for which a std::back_insert_iterator can be constructed with std::back_inserter. Back Insertion Sequence are refinements of CBackInsertable. They require more services than CBackInsertable, for instance read services or erase services.

Description of concept 'CBackInsertable'

Refinement of

Associated types :

• value_type: the type of object that can be inserted at the back.

Notation

• X : A type that is a model of CBackInsertable
• x : object of type X
• e : object of type value_type

Definitions

Valid expressions and semantics

Name	Expression	Type requirements	Return type	Precondition	Semantics	Post condition	Complexity
Add to back	x.push_back( e )				adds the element e at the end of object x

Invariants

Models

• Most standard linear containers: std::vector, std::list, std::deque
• CPositiveIrreducibleFraction is a refinement of CBackInsertable
• hence fractions: SternBrocot::Fraction, LighterSternBrocot::Fraction, LightSternBrocot::Fraction

Notes

Template Parameters:

T	the type that should be a model of CBackInsertable.
