def
result: histogram.FastMapHistogram
Called when a result is desired by the parent implementation.
Called when a result is desired by the parent implementation.
No guarantees are made that this will only be called after all visitation is complete. As a result, this should return an iterative result as cells are visited for full compatibility.

def
visit(raster: Raster[Tile], col: Int, row: Int): Unit
Called when the visitor requests a unit of computation for the given col and row.
Called when the visitor requests a unit of computation for the given col and row.
The visitor result should be updated within this method as appropriate for the implementation.
- col
The column in the grid being visited
- row
The row in the grid being visited
