Member Enumeration Documentation

◆ LayoutType

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.
