Detailed Description

template<class T>
struct Teuchos::OrdinalTraits< T >

This structure defines some basic traits for the ordinal field type.

Ordinal traits are an essential part of templated codes. This structure offers the basic traits of the templated ordinal type, like defining zero and one.

For the general type, or default implementation, an aborting function is defined which should restrict implementations from using ordinal traits other than the defined specializations.

Note

The defined specializations for OrdinalTraits are: int and long int.

Member Function Documentation

template<class T >

static T Teuchos::OrdinalTraits< T >::zero ( )

inlinestatic

Returns representation of zero for this ordinal type.

Definition at line 87 of file Teuchos_OrdinalTraits.hpp.

template<class T >

static T Teuchos::OrdinalTraits< T >::one ( )

inlinestatic

Returns representation of one for this ordinal type.

Definition at line 90 of file Teuchos_OrdinalTraits.hpp.

template<class T >

static T Teuchos::OrdinalTraits< T >::max ( )

inlinestatic

Returns a value designating the maximum value accessible by code using OrdinalTraits.

For a signed ordinal, this will typically be the maximum positive value. However, for an unsigned ordinal, this will typically be one less than the maximum value, because the maximum value will typically be reserved for designating an invalid value.

Examples:

CommandLineProcessor/cxx_main.cpp.

Definition at line 96 of file Teuchos_OrdinalTraits.hpp.

template<class T >

static T Teuchos::OrdinalTraits< T >::invalid ( )

inlinestatic

Returns a value designating an invalid number. For signed types, this is typically negative one; for unsigned types, it is typically the largest value.

Definition at line 99 of file Teuchos_OrdinalTraits.hpp.

template<class T >

static std::string Teuchos::OrdinalTraits< T >::name ( )

inlinestatic

Returns name of this ordinal type.

Definition at line 102 of file Teuchos_OrdinalTraits.hpp.

Member Data Documentation
