PK_redundant_merge_t

typedef int PK_redundant_merge_t;

Used in:

PK_TOPOL_delete_redundant_2_o_t
PK_TOPOL_identify_redundant_o_t

This datatype defines the scope of identifying/removing redundant topologies
from a topological set called 'topols'. It has three values:

PK_redundant_merge_in_c  : Consider only redundant topologies whose removal
                           would not change any neighbouring topology.

PK_redundant_merge_on_c  : Consider only redundant topologies whose removal
                           would not merge any supplied 'topols' with
                           neighbouring topology.

PK_redundant_merge_out_c : Consider any rendundant topology associated with
                           the supplied 'topols', including those whose
                           removal would result in 'topols' being merged with
                           neighbouring topology.

A neighbouring topology is one that is connected to the topology in
'topols', but is neither in 'topols' itself nor is a sub-topology of a
topology in 'topols'.
