GraphType (JGraphT : a free Java graph library)

All Known Implementing Classes:

DefaultGraphType
```
public interface GraphType
```
A graph type.
The graph type describes various properties of a graph such as whether it is directed/undirected or mixed, whether it contain self-loops (edges with the same source and target vertices), whether it contain parallel-edges (multiple edges with the same source and target) and whether it is weighted or not.

- Method Detail
  - isDirected
```
boolean isDirected()
```
    Returns true if all edges of the graph are directed, false otherwise.
    
    Returns:
    
    true if all edges of the graph are directed, false otherwise
  - isUndirected
```
boolean isUndirected()
```
    Returns true if all edges of the graph are undirected, false otherwise.
    
    Returns:
    
    true if all edges of the graph are undirected, false otherwise
  - isMixed
```
boolean isMixed()
```
    Returns true if the graph contain both directed and undirected edges, false otherwise.
    
    Returns:
    
    true if the graph contain both directed and undirected edges, false otherwise
  - isAllowingMultipleEdges
```
boolean isAllowingMultipleEdges()
```
    Returns true if and only if multiple edges are allowed in this graph. The meaning of multiple edges is that there can be many edges going from vertex v1 to vertex v2.
    
    Returns:
    
    true if and only if multiple edges are allowed.
  - isAllowingSelfLoops
```
boolean isAllowingSelfLoops()
```
    Returns true if and only if self-loops are allowed in this graph. A self loop is an edge that its source and target vertices are the same.
    
    Returns:
    
    true if and only if graph self-loops are allowed.
  - isAllowingCycles
```
boolean isAllowingCycles()
```
    Returns true if and only if cycles are allowed in this graph.
    
    Returns:
    
    true if and only if graph cycles are allowed.
  - isWeighted
```
boolean isWeighted()
```
    Returns true if and only if the graph supports edge weights.
    
    Returns:
    
    true if the graph supports edge weights, false otherwise.
  - isSimple
```
boolean isSimple()
```
    Returns true if the graph is simple, false otherwise.
    
    Returns:
    
    true if the graph is simple, false otherwise
  - isPseudograph
```
boolean isPseudograph()
```
    Returns true if the graph is a pseudograph, false otherwise.
    
    Returns:
    
    true if the graph is a pseudograph, false otherwise
  - isMultigraph
```
boolean isMultigraph()
```
    Returns true if the graph is a multigraph, false otherwise.
    
    Returns:
    
    true if the graph is a multigraph, false otherwise
  - isModifiable
```
boolean isModifiable()
```
    Returns true if the graph is modifiable, false otherwise.
    
    Returns:
    
    true if the graph is modifiable, false otherwise
  - asDirected
```
GraphType asDirected()
```
    Create a directed variant of the current graph type.
    
    Returns:
    
    a directed variant of the current graph type
  - asUndirected
```
GraphType asUndirected()
```
    Create an undirected variant of the current graph type.
    
    Returns:
    
    an undirected variant of the current graph type
  - asMixed
```
GraphType asMixed()
```
    Create a mixed variant of the current graph type.
    
    Returns:
    
    a mixed variant of the current graph type
  - asUnweighted
```
GraphType asUnweighted()
```
    Create an unweighted variant of the current graph type.
    
    Returns:
    
    an unweighted variant of the current graph type
  - asWeighted
```
GraphType asWeighted()
```
    Create a weighted variant of the current graph type.
    
    Returns:
    
    a weighted variant of the current graph type
  - asModifiable
```
GraphType asModifiable()
```
    Create a modifiable variant of the current graph type.
    
    Returns:
    
    a modifiable variant of the current graph type
  - asUnmodifiable
```
GraphType asUnmodifiable()
