- Method Detail
  - addVertex
```
void addVertex(Vertex<V,E> vertex)
```
    Adds a vertex to the graph state
    
    Parameters:
    
    vertex - the vertex to add
  - addEdge
```
void addEdge(Edge<V,E> edge,
             Vertex<V,E> source,
             Vertex<V,E> target)
```
    Adds an edge between given source and target vertex
    
    Parameters:
    
    edge - the edge to add
    
    source - the source vertex
    
    target - the target vertex
    
    Throws:
    
    IllegalStateException - if the vertices were not added before
  - readonly
```
default GraphStateAccessor<V,E> readonly()
```
    Returns a readonly instance of the given graph state
    
    Returns:
    
    the current graph state as ready only representation
