`edge.getId()`

Returns the identifier of the edge.

*Examples*

    arango> v = g.addVertex("v");
    Vertex("v")
    
    arango> e = g.addEdge(v, v, 1, "self");
    Edge(1)
    
    arango> e.getId();
    1

`edge.getInVertex()`

Returns the vertex at the head of the edge.

*Examples*

    arango> v1 = g.addVertex(1);
    Vertex(1)
    
    arango> e = g.addEdge(v, v, 2, "self");
    Edge(2)
    
    arango> e.getInVertex();
    Vertex(1)

`edge.getLabel()`

Returns the label of the edge.

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)
    
    arango> e = g.addEdge(v, v, 2, "knows");
    Edge(2)
    
    arango> e.getLabel();
    knows

`edge.getOutVertex()`

Returns the vertex at the tail of the edge.

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)
    
    arango> e = g.addEdge(v, v, 2, "self");
    Edge(2)
    
    arango> e.getOutVertex();
    Vertex(1)

`edge.getPeerVertex( vertex)`

Returns the peer vertex of the edge and the vertex.

*Examples*

    arango> v1 = g.addVertex("1");
    Vertex("1")
    arango> v2 = g.addVertex("2");
    Vertex("2")
    arango> e = g.addEdge(v1, v2, "1->2", "knows");
    Edge("1->2")
    arango> e.getPeerVertex(v1);
    Vertex(2)

`edge.getProperty( name)`

Returns the property name an edge.

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)

    arango> e = g.addEdge(v, v, 2, "self", { "weight" : 10 });
    Edge(2)

    arango> e.getProperty("weight");
    10

`edge.getPropertyKeys()`

Returns all propety names an edge.

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)
        
    arango> e = g.addEdge(v, v, 2, "self", { weight: 10 })
    Edge(2)
    
    arango> e.getPropertyKeys()
    [ "weight" ]
    
    arango> e.setProperty("name", "Hugo");
    Hugo
    
    arango> e.getPropertyKeys()
    [ "weight", "name" ]

`edge.properties()`

Returns all properties and their values of an edge

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)
    
    arango> e = g.addEdge(v, v, 2, "knows");
    Edge(2)
    
    arango> e.properties();
    { "weight" : 10 }

`edge.setProperty( name, value)`

Changes or sets the property name an edges to value.

*Examples*

    arango> v = g.addVertex(1);
    Vertex(1)
    
    arango> e = g.addEdge(v, v, 2, "self", { weight: 10 })
    Edge(2)
    
    arango> e.getPropert("weight")
    10
    
    arango> e.setProperty("weight", 20);
    20
    
    arango> e.getPropert("weight")
    20
