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. |

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
