This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).
The newest version!

/**
* A builder for constructing instances of {@link MutableGraph} or {@link ImmutableGraph} with
* user-defined properties.
*
* A {@code Graph} built by this class has the following default properties:
*
*
* - does not allow self-loops
*
- orders {@link Graph#nodes()} in the order in which the elements were added (insertion
* order)
*
*
* {@code Graph}s built by this class also guarantee that each collection-returning accessor
* returns a (live) unmodifiable view; see the external
* documentation for details.
*
*
Examples of use:
*
*
{@code
* // Building a mutable graph
* MutableGraph graph = GraphBuilder.undirected().allowsSelfLoops(true).build();
* graph.putEdge("bread", "bread");
* graph.putEdge("chocolate", "peanut butter");
* graph.putEdge("peanut butter", "jelly");
*
* // Building an immutable graph
* ImmutableGraph immutableGraph =
* GraphBuilder.undirected()
* .allowsSelfLoops(true)
* .immutable()
* .putEdge("bread", "bread")
* .putEdge("chocolate", "peanut butter")
* .putEdge("peanut butter", "jelly")
* .build();
* }
*
* @author James Sexton
* @author Joshua O'Madadhain
* @param The most general node type this builder will support. This is normally {@code Object}
* unless it is constrained by using a method like {@link #nodeOrder}, or the builder is
* constructed based on an existing {@code Graph} using {@link #from(Graph)}.
* @since 20.0
