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. |

Sort comparison predicate.
std::sort compliant comparison operator

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
