esriNAODCostMatrixType Constants

OD cost matrix type.

Constant	Value	Description
esriNAODCostMatrixNone	0	No cost matrix.
esriNAODCostMatrixFull	1	Full cost matrix.
esriNAODCostMatrixUpdate	2	Updated cost matrix, with removal of unused origins and destinations.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.

The values within this enumeration are used to indicate the type of matrix to be populated.

The esriNAODCostMatrixType enumeration has the following values:

esriNAODCostMatrixNone - this value indicates that no cost matrix should be populated
esriNAODCostMatrixFull - this value indicates that a cost matrix is created and fully populated each time the solve is called
esriNAODCostMatrixUpdate - this value indicates that subsequent solves of a cost matrix update the existing matrix based on the changes to the origins, destinations, and list of cost attributes. The solver will not check on changes due to other aspects such as barriers or hierarchy settings.
