Value Members

  1. def result: Array[histogram.StreamingHistogram]

    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.

    returns

  2. def visit(raster: Raster[MultibandTile], 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
