Description

operator()(s32, s32)

Sort comparison predicate.

OrderData(s32, s32)

Order two indices.

 

bool Geo::IdentDataCompare::operator()

public: bool operator()
(
    s32 i0,
    s32 i1
) const

Sort comparison predicate.

std::sort compliant comparison operator

 

s32 Geo::IdentDataCompare::OrderData

public: s32 OrderData
(
    s32 i0,
    s32 i1
) const

Order two indices.

Given two indices, return -1 if v[i0]<v[i1], 0 if v[i0]==v[i1] and 1 if v[i0]>v[u1]. This is the same as the C qsort comparison function. If allows us to identify == explicitly
