Member Enumeration Documentation

enum ns3::GridPositionAllocator::LayoutType

Determine whether positions are allocated row first or column first.

Enumerator:

ROW_FIRST	In row-first mode, positions are allocated on the first row until N positions have been allocated. Then, the second row located a yMin + yDelta is used to allocate positions.
COLUMN_FIRST	In column-first mode, positions are allocated on the first column until N positions have been allocated. Then, the second column located a xMin + xDelta is used to allocate positions.
