/root/tmp/opm-verteq-release-2015.10-final/opm/verteq/utility/runlen.hpp

Regards a set of (member) variables as a run-length encoded matrix.

Each column can have a variable number of rows. Although the values of the matrix can be changed, its sparsity cannot, i.e. one cannot remove or add new elements to a column.

Use this class to access and iterate over a run-length encoded matrix in the format that is used by UnstructuredGrid without having to worry about getting the indexing right.

Template Parameters

T	Datatype for the extra data that should be stored for each element, e.g. double.

RunLenView <int> faces_in_cell (
    g.number_of_cells,
    g.cell_facepos,
    g.cell_faces
);

int num_local_faces = faces_in_cell.size (cellno);
int first_local_face = faces_in_cell [cellno] [0];

Notice if you want to loop through every item and know where you are (because you intend to use this as an index in another matrix), you can do:
