Graph (telekom-workflow-engine 1.2.7 API)

All Known Implementing Classes:

GraphImpl
```
public interface Graph
```
A Graph corresponds to a workflow definition. It has a set of Nodes, which correspond to actions that need to be taken for the workflow to complete. It also has a set of Transitions which define the order of execution between the nodes.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`boolean`	`getKeepHistory()`
`String`	`getName()` Returns the graph's name, which should be unique.
`Node`	`getNode(int id)` Returns the graph's node with the given id.
`Collection<Node>`	`getNodes()` Returns the list of all nodes in the graph.
`List<Transition>`	`getOutputTransitions(Node node)` Returns a list of transitions which have the given node as their starting point.
`Transition`	`getOutputTransitions(Node node, String name)` Returns the transition which has the given node as their starting point and the given name, or `null` if no such transition exists.
`Node`	`getStartNode()` Returns the graph's start node.
`List<Transition>`	`getTransitions()` Returns the list of all transitions in the graph.
`int`	`getVersion()` Returns the version number of the graph.

- Method Detail
  - getName
```
String getName()
```
    Returns the graph's name, which should be unique. Different versions with the same name may exist, but each of them should have a unique version number.
    
    Returns:
    
    the graph's name
  - getVersion
```
int getVersion()
```
    Returns the version number of the graph. Different versions of a graph may exists. Newer versions of the graph should have higher version numbers than older versions. A graph can be uniquely identified by name and version number.
    
    Returns:
    
    the graph's version
  - getKeepHistory
```
boolean getKeepHistory()
```
  - getStartNode
```
Node getStartNode()
```
    Returns the graph's start node. The start node is the node where to start execution when creating a new GraphInstance. A non-empty graph must define a start node.
    
    Returns:
    
    the node at which to start a workflow instance
  - getNode
```
Node getNode(int id)
```
    Returns the graph's node with the given id. Every node within a graph must be have a unique id.
    
    Returns:
    
    the graph's node with the given id or null if the graph does not contain a node with the given id.
  - getNodes
```
Collection<Node> getNodes()
```
    Returns the list of all nodes in the graph.
    
    Returns:
    
    list of all nodes in the graph
  - getTransitions
```
List<Transition> getTransitions()
```
    Returns the list of all transitions in the graph.
    
    Returns:
    
    list of all transitions in the graph
  - getOutputTransitions
```
List<Transition> getOutputTransitions(Node node)
```
    Returns a list of transitions which have the given node as their starting point. The list may be empty but will never be null.
    
    Parameters:
    
    node - A node belonging to this graph
    
    Returns:
    
    A list of transitions
  - getOutputTransitions
```
Transition getOutputTransitions(Node node,
                                String name)
```
    Returns the transition which has the given node as their starting point and the given name, or null if no such transition exists.
    
    Parameters:
    
    node - A node belonging to this graph
    
    name - A transition name
    
    Returns:
    
    A list of transitions
