/**
|
|
64 |
* This class is the base class for all nodes. It represents a node that can be inserted in a
|
|
65 |
* {@link Graph}.
|
|
66 |
* <p>
|
|
67 |
* Once a node has been added to a graph, it has a graph-unique {@link #id()}. Edges in the
|
|
68 |
* subclasses are represented with annotated fields. There are two kind of edges : {@link Input} and
|
|
69 |
* {@link Successor}. If a field, of a type compatible with {@link Node}, annotated with either
|
|
70 |
* {@link Input} and {@link Successor} is not null, then there is an edge from this node to the node
|
|
71 |
* this field points to.
|
|
72 |
* <p>
|
|
73 |
* Nodes which are be value numberable should implement the {@link ValueNumberable} interface.
|
|
74 |
*
|
|
75 |
* <h1>Assertions and Verification</h1>
|
|
76 |
*
|
|
77 |
* The Node class supplies the {@link #assertTrue(boolean, String, Object...)} and
|
|
78 |
* {@link #assertFalse(boolean, String, Object...)} methods, which will check the supplied boolean
|
|
79 |
* and throw a VerificationError if it has the wrong value. Both methods will always either throw an
|
|
80 |
* exception or return true. They can thus be used within an assert statement, so that the check is
|
|
81 |
* only performed if assertions are enabled.
