List of Concepts

See Insight/Code/Common/itkConceptChecking.h.

Index Concept Description
1 DefaultConstructible Concept requiring T to have a default constructor.
2 CopyConstructible Concept requiring T to have a copy constructor.
3 Convertible Concept requiring T1 to be convertible to T2.
4 Assignable Concept requiring T to have operator =.
5 LessThanComparable Concept requiring T1 to have operators < and <= with a right-hand operator of type T2.
6 EqualityComparable Concept requiring T1 to have operators == and != with a right-hand operator of type T2.
7 Comparable Concept requiring T1 to have operators <, >, <=, >=, ==, != with a right-hand operator of type T2.
8 AdditiveOperators Concept requiring T1 to have operators +, -, +=, -= in the form T3 = T1 op T2.
9 MultiplicativeOperators Concept requiring T1 to have operators *, /, *=, /= in the form T3 = T1 op T2.
10 Signed Concept requiring T to be signed.
11 SameType Concept requiring T1 and T2 to be the same type.
12 SameDimension Concept requiring D1 and D2 to be the same dimension.
13 GreaterThanComparable Concept requiring T1 to have operators > and >= with a right-hand operator of type T2.
14 LogicalOperators Concept requiring T1 to have operators &, I, ^, &=, I=, ^= in the form T3 = T1 op T2.
15 NotOperator Concept requiring T to have operator !.
16 IncrementDecrementOperators Concept requiring T to have operators ++ and --.
17 OStreamWritable Concept requiring T to be writable to an ostream.
18 HasNumericTraits Concept requiring T to have NumericTraits.
19 HasPixelTraits Concept requiring T to have PixelTraits.
20 HasJoinTraits Concept requiring T to have JoinTraits.
21 SameDimensionOrMinusOne Concept requiring D1 and D2 to be the same dimension or D2-1 = D2.

Proposed concept additions

Additional concepts for requiring integer or noninteger datatypes should be added to the toolkit. NumericTraits defines static boolean constants

  • is_bounded
  • is_exact
  • is_iec559 (???)
  • is_integer
  • is_modulo
  • is_signed
  • is_specialized
  • tinyness_before

These traits can be used to define concepts in a manner similar to the Signed concept. We should consider separating the concepts of integer, non-integer, floating point so that we can expand our native datatypes to include a fixed point representation.

The concepts below are poorly named. We should not have a concept called Integer since a user could confuse the name of the concept with a datatype. Unfortunately, none of the current concepts have the word concept in their name. We could follow NumericTraits, and make the new concepts called IsInteger.

Index Concept Description
13 Integer Concept requiring T to be an integer.
14 Noninteger Concept requiring T to be noninteger (floating point or fixed point).
15 FloatingPoint Concept requiring T to be floating point (not integer and not fixed point)
16 FixedPoint Concept requiring T to be an ITK fixed point representation (not integer and not floating point)
