DGraph (aamwriter 1.0.0 API)

```
public class DGraph
extends Object
```
Classes in aamwriter.modeldesigner package model the topology described in UI. DGraph class is the root of the topology model. It is in charge of reading a description of the topology in json and build the hierarchy of classes. NOTE: The preferred way to set the frontend node of the application is specifying it in the application_requirements element of the json topology. If not specified, it falls back to the first node found with "frontend" property set to true. If not specified, the frontend node is calculated as the first node found without incoming links. This may lead to unexpected behaviour. Due to optimizer constraint, only one frontend node is allowed.
