NAContext | The analysis and problem definition container. |
Remarks
The INAContextEdit interface is used to set up some of the internal references to objects and to manage edit operations within the NAClasses.
You must call Bind after calling CreateContext on NASolver. Solvers must call Initialize when they create the NAContext. If updating NALocationObjects outside of ArcMap, the methods to perform edits within an edit operation can be used. However, if edits are being done within ArcMap, it is recommended that the edit operation methods on the NAWindow's INAWindow be used instead so ArcMap's undo/redo stack remains in sync.
The Result and Solver properties should only be set from within a custom solver.
