Detailed Description

A sequence of unique and ordered indices in one segment of an IndexMask. The segment as a whole has an int64_t index offset that is added to each referenced int16_t index.

◆ shift()

IndexMaskSegment blender::index_mask::IndexMaskSegment::shift ( const int64_t shift ) const

inline

Get a new segment where each index is modified by the given amount. This works in constant time, because only the offset value is changed.
