class Geo::IdentDataCompare

Comparison class for std::sort.

Compares the data in the DataArray byte by byte (one DataStride chunk at the time), ignoring bytes that have a value of 0 in the DataByteMask.

Variables

Name	Description
const u8 * m_DataArray	Array with data buffer.
const u8 * m_DataByteMask	Byte mask array with size of at least m_DataStride. Any non-zero value.
s32 m_DataStride	Size of a data element in bytes.

Functions

Name	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
