The n'th node with 0 <= n < arity.
The n'th node with 0 <= n < arity.
Number of nodes linked by this Edge.
Number of nodes linked by this Edge. At least two nodes are linked. In case of a hook, the two nodes are identical. Hyperedges may link more than two nodes.

It is a prerequisite for edge-classes to implement this method.
It is a prerequisite for edge-classes to implement this method. Otherwise
they cannot be passed to a Graph.
Graph calls this method internally to obtain a new instance of the
edge passed to Graph with nodes of the type of the inner class NodeT
which itself contains the outer node.

true if any source end of this edge fulfills pred.
true if node is a source of this edge.
true if node is a source of this edge. In case this edge is undirected this method maps to isAt.
true if any target end of this edge fulfills pred.
true if any target end of this edge fulfills pred.
true if node is a target of this edge.
true if node is a target of this edge. In case this edge is undirected this method maps to isAt.

true if node is incident with this edge.

true if this is a hyperedge that is it may have more than two ends.
true if this edge is labeled.
true if this edge is labeled. See also label.
true if this edge produces a self-loop.
true if this edge produces a self-loop.
In case of a non-hyperedge, a loop is given if the incident nodes are equal.
In case of a directed hyperedge, a loop is given if the source is equal to
any of the targets.
In case of an undirected hyperedge, a loop is given if any pair of incident
nodes has equal nodes.
Same as undirected.

A function to determine whether the arity of the passed Product
of nodes (that is the number of edge ends) is valid.
A function to determine whether the arity of the passed Product
of nodes (that is the number of edge ends) is valid.
This function is called on every edge-instantiation
by validate that throws EdgeException if this method returns false.
This method may be overridden to enforce additional validation at edge creation time.
This method may be overridden to enforce additional validation at edge
creation time. Be careful to call super.isValidCustom when overriding.

Iterator for the nodes (end-points) of this edge.
The label of this edge.
The label of this edge. If Graph's edge type parameter has been inferred or set
to a labeled edge type all contained edges are labeled. Otherwise you should
assert, for instance by calling isLabeled, that the edge instance is labeled
before calling this method.
Note that label is normally not part of the edge key (hashCode). As a result,
edges with different labels connecting the same nodes will be evaluated as equal
and thus added once and only once to the graph.
In case you need multi-edges based on different labels
you should either make use of a predefined key-labeled edge type such as LDiEdge
or define a custom edge class that mixes in ExtendedKey and adds label to
keyAttributes.
UnsupportedOperationException if the edge is non-labeled.

Performs basic, inevitable edge validation.
Performs basic, inevitable edge validation. Among others, ensures
that nodes ne null and no edge end eq null.
This validation method must be called in the constructor of any edge class
that directly extends or mixes in EdgeLike. To perform additional custom
validation isValidCustom is to be overridden.
EdgeException if any of the basic validations or of eventually
supplied additional validations fails.
The weight of this edge with a default of 1.
The weight of this edge with a default of 1.
Note that weight is normally not part of the edge key (hashCode). As a result,
edges with different weights connecting the same nodes will be evaluated as equal
and thus added once and only once to the graph.
In case you need multi-edges based on different weights
you should either make use of a predefined key-weighted edge type such as WDiEdge
or define a custom edge class that mixes in ExtendedKey and adds weight to
keyAttributes.
For weight types other than Long you may either convert then to Long
prior to edge creation or define a custom edge class that includes the
weight of the appropriate type and overrides def weight to provide the
required conversion to Long.
