Detailed Description

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

This concept is implemented by objects matching a partial order.

Parameters

T	Type of compared items.

Member Function Documentation

compare()

static int compare ( const T &  v1, const T &  v2  )

static

Perform a soft comparison: any value may be compared.

Parameters

v1	Value 1 to compare.
v2	Value 2 to compare.

Returns

A bit field composed by EQUAL, LESS, GREATER.

equals()

static bool equals ( const T &  v1, const T &  v2  )

static

Test for equality.

Parameters

v1	Value 1 to compare.
v2	Value 2 to compare.

Returns

True if both values are equals, false else.

greaterThan()

static bool greaterThan ( const T &  v1, const T &  v2  )

static

Test for greatness.

Parameters

v1	Value 1 to compare.
v2	Value 2 to compare.

Returns

True if v1 is greater than v2, false else.

lessThan()

static bool lessThan ( const T &  v1, const T &  v2  )

static

Test for lessness.

Parameters

v1	Value 1 to compare.
v2	Value 2 to compare.

Returns

True if v1 is less than v2, false else.

Member Data Documentation

EQUAL

const int EQUAL = 0x001

static

The bit 0 asserts equality relation.

GREATER

const int GREATER = 0x100

static

The bit 2 asserts the superioritiy relation.

LESS

const int LESS = 0x010

static

The bit 1 asserts the inferiority relation.

UNCOMP

const int UNCOMP = 0x000

static

All bits to zero shows that both values are uncomparable.
