NetworkAnalyst (Oracle Spatial and Graph Java API Reference)

java.lang.Object
- oracle.spatial.network.lod.NetworkAnalyst

```
public class NetworkAnalyst
extends java.lang.Object
```
This class is the single entry point to all the network analysis operations supported by NDM LOD. To get an instance of this class, use
```
    NetworkAnalyst analyst = LODNetworkManager.getNetworkAnalyst(networkIO);
  
```
where networkIO is an NetworkIO object for the network of interest.
Users can define their own link cost calculators or node cost calculators. Note that if you choose to use your own link or node cost calculators, you must set both link and node cost calculators in pairs, that is, there must be the same number of link cost calculators as that of the node cost calculators, and the ith link cost calculator must correspond to the ith node cost calculator.
