public static interface Graph.Edge
An interface describing an edge in a Graph
. Please
see equals( Object )
for important
information on implementing this interface.
Method Summary | |
---|---|
boolean |
equals(Object object)
Returns whether or not some other object is equal to this one. |
Object |
getHead()
Returns the node which is the head of this Graph.Edge . |
Object |
getOtherEndpoint(Object node)
Returns the node which is at the other end of this Graph.Edge than the specified node. |
Object |
getTail()
Returns the node which is the tail of this Graph.Edge . |
Object |
getUserObject()
Returns the user object contained in this Graph.Edge . |
int |
hashCode()
Returns the hash code for this Graph.Edge . |
boolean |
isDirected()
Returns whether or not this Graph.Edge is
directed. |
void |
setUserObject(Object object)
Sets the user object contained in this Graph.Edge . |

object
- the user object to replace the one in this

ClassCastException
- if the class of
object
prevents it from being added to the
Graph
containing this Graph.Edge

IllegalArgumentException
- if some aspect of
object
prevents it from being added to the
Graph
containing this Graph.Edge
.
IllegalArgumentException
- if object
is
null
and the Graph
containing this
Graph.Edge
does not not permit
null
edges.

- if this method is
not supported by this Graph.Edge

Graph.Edge
than the specified node.
IllegalArgumentException
- if this
Graph.Edge
is not incident on the specified
node.boolean equals(Object object)
Graph.Edges
only be .equals()
when they refer to the same actual edge in the graph.
Which edge this is does not change when the contained
user-defined object changes. In a multigraph, the
endpoints and contained user-defined object are generally
not sufficiently distinguishing characteristics.
Accepting the default implementation from
Object
, which uses reference equality, should
be preferred unless Graph.Edges
are lazily
created on demand.

Since it is mutable, the contained user-defined object
should not be used when computing the hash code.
