Detailed Description

template<class T>
class elm::concept::PartialComparator< T >

This concept is implemented by objects matching a partial order.

Parameters
TType of compared items.

Member Function Documentation

template<class T >
static int elm::concept::PartialComparator< T >::compare ( const T &  v1,
const T &  v2 
)
static

Perform a soft comparison: any value may be compared.

Parameters
v1Value 1 to compare.
v2Value 2 to compare.
Returns
A bit field composed by EQUAL, LESS, GREATER.
template<class T >
static bool elm::concept::PartialComparator< T >::equals ( const T &  v1,
const T &  v2 
)
static

Test for equality.

Parameters
v1Value 1 to compare.
v2Value 2 to compare.
Returns
True if both values are equals, false else.
template<class T >
static bool elm::concept::PartialComparator< T >::greaterThan ( const T &  v1,
const T &  v2 
)
static

Test for greatness.

Parameters
v1Value 1 to compare.
v2Value 2 to compare.
Returns
True if v1 is greater than v2, false else.
template<class T >
static bool elm::concept::PartialComparator< T >::lessThan ( const T &  v1,
const T &  v2 
)
static

Test for lessness.

Parameters
v1Value 1 to compare.
v2Value 2 to compare.
Returns
True if v1 is less than v2, false else.

Member Data Documentation

template<class T >
const int elm::concept::PartialComparator< T >::EQUAL = 0x001
static

The bit 0 asserts equality relation.

template<class T >
const int elm::concept::PartialComparator< T >::GREATER = 0x100
static

The bit 2 asserts the superioritiy relation.

template<class T >
const int elm::concept::PartialComparator< T >::LESS = 0x010
static

The bit 1 asserts the inferiority relation.

template<class T >
const int elm::concept::PartialComparator< T >::UNCOMP = 0x000
static

All bits to zero shows that both values are uncomparable.
