Detailed Description

Connectivity contiguously composed of multiple BlockConnectivityImpl.

Author: Willem Deconinck

Container for connectivity tables that are layed out in memory as multiple BlockConnectivities stitched together. This is e.g. the case for a element-node connectivity, with element-types grouped together:

connectivity = [
   # triangles  (block 0)
       1   2   3
       4   5   6
       7   8   9
      10  11  12
   # quadrilaterals (block 1)
      13  14  15  16
      17  18  19  20
      21  22  23  24
]

This class can also be interpreted as a atlas::IrregularConnectivity without distinction between blocks

There are 2 modes of construction:

It wraps existing raw data
It owns the connectivity data

In case ATLAS_HAVE_FORTRAN is defined (which is usually the case), the raw data will be stored with base 1 for Fortran interoperability. The operator(row,col) will then do the conversion to base 0.

In the first mode of construction, the connectivity table cannot be resized. In the second mode of construction, resizing is possible
