Concept UnsignedIntegerConcept
An integral type without a sign.

Extends IntegerConcept
All Extended AssignableConcept, ComparableConcept, CopyConstructibleConcept, DefaultConstructibleConcept, DestructibleConcept, EqualityComparableConcept, IntegerConcept, LessThanComparableConcept
Defined in <seqan/basic.h>
Signature UnsignedIntegerConcept<T>

Detailed Description

Expects an instance of type T to represent non-negative integral values and to provide the same operations as unsigned int. Every type T that fulfills the IntegerConcept fulfills either the SignedIntegerConcept or the UnsignedIntegerConcept.


//SEQAN_CONCEPT_ASSERT((UnsignedIntegerConcept<int>));                          // fails to compile
SEQAN_CONCEPT_ASSERT((UnsignedIntegerConcept<unsigned short>));

std::cout << Is<UnsignedIntegerConcept<char> >::VALUE << std::endl;             // 0
std::cout << Is<UnsignedIntegerConcept<int> >::VALUE << std::endl;              // 0
std::cout << Is<UnsignedIntegerConcept<unsigned short> >::VALUE << std::endl;   // 1
std::cout << Is<UnsignedIntegerConcept<double> >::VALUE << std::endl;           // 0

Valid Expressions

T a;
unsigned int b;

a = 1u;
b = a;

std::cout << static_cast<T>(0) < static_cast<T>(-1) << std::endl;  // 1
