Member Enumeration Documentation

◆ 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.

Definition at line 117 of file position-allocator.h.
