To say whether arrays etc are owned by CoinSnapshot. More... |
It is designed to be snapshot of a problem at a node in tree
The class may or may not own the arrays - see owned_
Querying a problem that has no data associated with it will result in zeros for the number of rows and columns, and NULL pointers from the methods that return arrays.
